Pickardj79: /* Update players score */

{{Studio_Framework_Navigation}}

This is the main file for your game interface. Here you will define:

* Which actions on the page will generate calls to the server.
* What happens when you get a notification for a change from the server and how it will show in the browser.

== File structure ==

The details of how the file is structured are described below with comments on the code skeleton provided to you.

Here is the basic structure:

* '''constructor''': here you can define global variables for your whole interface.
* '''setup''': this method is called when the page is refreshed, and sets up the game interface.
* '''onEnteringState''': this method is called when entering a new game state. You can use it to customize the view for each game state.
* '''onLeavingState''': this method is called when leaving a game state.
* '''onUpdateActionButtons''': called when entering a new state, in order to add action buttons to the status bar.
* ''(utility methods)'': this is where you can define your utility methods.
* ''(player's actions)'': this is where you can write your handlers for player actions on the interface (example: click on an item).
* '''setupNotifications''': this method associates notifications with notification handlers. For each game notification, you can trigger a javascript method to handle it and update the game interface.
* ''(notification handlers)'': this is where you define the notifications handlers associated with notifications in '''setupNotifications''', above.

== General tips ==

; this.player_id
: ID of the player on whose browser the code is running.

; this.isSpectator
: Flag set to true if the user at the table is a spectator (not a player).
: Note: This is a variable, not a function.
: Note: If you want to hide an element from spectators, you should use [[Game_interface_stylesheet:_yourgamename.css#spectatorMode|CSS 'spectatorMode' class]].

; this.gamedatas
: Contains the initial set of data to init the game, created at game start or by game refresh (F5).
: You can update it as needed to keep an up-to-date reference of the game on the client side if you need it. (Most of the time this is unnecessary).

; this.isCurrentPlayerActive()
: Returns true if the player on whose browser the code is running is currently active (it's his turn to play).

; this.getActivePlayerId()
: Return the ID of the active player, or null if we are not in an "activeplayer" type state.

; this.getActivePlayers()
: Return an array with the IDs of players who are currently active (or an empty array if there are none).

; this.bRealtime
: Return true if the game is in realtime. Note that having a distinct behavior in realtime and turn-based should be exceptional.

; typeof g_replayFrom != 'undefined'
: Returns true if the game is in instant replay mode (replay during the game)

; g_archive_mode
: Returns true if the game is in archive mode (advanced replay after the game has ended)

---

You may consider making a function like this, to detect if the game is in a read-only state:

// Returns true for spectators, instant replay (during game), archive mode (after game end)
isReadOnly: function () {
return this.isSpectator || typeof g_replayFrom != 'undefined' || g_archive_mode;
}

== Dojo framework ==

BGA uses the [http://dojotoolkit.org/ Dojo Javascript framework].

The Dojo framework allows us to do complex things more easily. The BGA framework uses Dojo extensively.

To implement a game, you only need to use a few parts of the Dojo framework. All the Dojo methods you need are described on this page.

== Javascript minimization (before July 2020) ==

For performance reasons, when deploying a game the js code is minimized using ShrinkSafe (based on ECMASCRIPT version 3). Some advanced syntax may not be compatible with this process. In particular:
* You should not use reserved keywords from the javascript language as variables.
* You should not declare default argument values in function declarations. The following syntax is invalid for ShrinkSafe: '''function myFunc(requiredArg, optionalArg = 'defaultValue') {}'''
* You should not use '''let''' or '''const''' to declare variables.

'''Tip:''' a developer encountering some problems with this has successfully used [http://plugins.netbeans.org/plugin/58580/jshint JSHint] on NetBeans to evaluate code to make it compatible for ECMAScript 3. With the plugin installed, set the below options in '''.jshintrc''' file, and then open '''Action Items''' window (in NetBeans):<pre>{ "maxerr": 999, "esversion": 3 }</pre>

'''Tip:''' some online tools also allow to convert between different versions of javascript, such as https://www.typescriptlang.org/play or https://babeljs.io/ or https://extendsclass.com/javascript-fiddle.html

== Javascript minimization (after July 2020) ==

For performance reasons, when deploying a game the javascript code is minimized using '''terser''' (https://github.com/terser/terser). This minifier works with modern javascript syntax. From your project "Manage game" page, you can now test a minified version of jour javascript on the studio (and revert to the original).

== Accessing and manipulating the DOM ==

'''$('some_html_element_id')'''

The $() function is used to get an HTML element using its "id" attribute.

Example 1: modify the content of a "span" element:

<pre>
In your HTML code:
<span id="a_value_in_the_game_interface">1234</span>

In your Javascript code:
$('a_value_in_the_game_interface').innerHTML = "9999";
</pre>

Note: $() is the standard method to access some HTML element with the BGA Framework. You should not use the '''getElementById''' function.

'''dojo.style'''

With dojo.style you can modify the CSS property of any HTML element in your interface.

Examples:

<pre>
// Make an element disappear
dojo.style( 'my_element', 'display', 'none' );

// Give an element a 2px border
dojo.style( 'my_element', 'borderWidth', '2px' );

// Change the background position of an element
// (very practical when you are using CSS sprites to transform an element to another)
dojo.style( 'my_element', 'backgroundPosition', '-20px -50px' );
</pre>

Note: you must always use dojo.style to modify the CSS properties of HTML elements.

Note²: if you have to modify several CSS properties of an element, or if you have a complex CSS transformation to do, you should consider using dojo.addClass/dojo.removeClass (see below).

'''dojo CSS classes manipulation'''

In many situations, many small CSS property updates can be replaced by a CSS class change (i.e., you add a CSS class to your element instead of applying all modifications manually).

Advantages are:
* All your CSS stuff remains in your CSS file.
* You can add/remove a list of CSS modifications with a simple function and without error.
* You can test whether you applied the CSS to an element with the '''dojo.hasClass''' method.

Example from ''Reversi'':

<pre>
// We add "possibleMove" to an element
dojo.addClass( 'square_'+x+'_'+y, 'possibleMove' );

// In our CSS file, the class is defined as:
.possibleMove {
background-color: white;
opacity: 0.2;
filter:alpha(opacity=20); /* For IE8 and earlier */
cursor: pointer;
}

// So we've applied 4 CSS property changes in one line of code.

// ... and when we need to check if a square is a possible move on the client side:
if( dojo.hasClass( 'square_'+x+'_'+y, 'possibleMove' ) )
{ ... }

// ... and if we want to remove all possible moves in one line of code (see "dojo.query" method):
dojo.query( '.possibleMove' ).removeClass( 'possibleMove' );
</pre>

Conclusion: We encourage you to use '''dojo.addClass''', '''dojo.removeClass''' and '''dojo.hasClass''' to make your life easier :)

'''dojo.query'''

With dojo.query, you can query a bunch of HTML elements with a single function, with a "CSS selector" style.

Example:
<pre>
// All elements with class "possibleMove":
var elements = dojo.query( '.possibleMove' );

// Count number of tokens (i.e., elements of class "token") on the board (i.e., the element with id "board"):
dojo.query( '#board .token' ).length;
</pre>

But what is really cool with dojo.query is that you can combine it with almost all methods above.

Examples:
<pre>
// Trigger a method when the mouse enter in any element with class "meeple":
dojo.query( '.meeple' ).connect( 'onmouseenter', this, 'myMethodToTrigger' );

// Hide all meeples who are on the board
dojo.query( '#board .meeple' ).style( 'display', 'none' );
</pre>

'''dojo.place'''

dojo.place is the best function to insert HTML code somewhere in your game interface without breaking something. It is much better to use than the '''innerHTML=''' method if you must insert HTML tags and not only values.

<pre>
// Insert your HTML code as a child of a container element
dojo.place( "<your html code>", "your_container_element_id" );

// Replace the container element with your new html
dojo.place( "<your html code>", "your_container_element_id", "replace" );

</pre>

The third parameter of dojo.place can take various interesting values:

"replace" : (see description above).

"first" : Places the node as a child of the reference node. The node is placed as the first child.

"last" (default) : Places the node as a child of the reference node. The node is placed as the last child.

"before" : places the node right before the reference node.

"after" : places the node right after the reference node.

"only" : replaces all children of the reference node with the node.

positif integer : This parameter can be a positif integer. In this case, the node will be placed as a child of the reference node with this number (counting from 0). If the number is more than number of children, the node will be appended to the reference node making it the last child.

See also full doc on dojo.place : [https://dojotoolkit.org/reference-guide/1.7/dojo/place.html]

Usually, when you want to insert some piece of HTML in your game interface, you should use "[[Game_layout:_view_and_template:_yourgamename.view.php_and_yourgamename_yourgamename.tpl#Javascript_templates|Javascript templates]]".

'''addStyleToClass: function( cssClassName, cssProperty, propertyValue )'''

Same as dojo.style(), but for all the nodes set with the specified cssClassName

=== Animations ===

'''Dojo Animations'''

BGA animations is based on Dojo Animation ([http://dojotoolkit.org/documentation/tutorials/1.8/animation/ see tutorial here]).

However, most of the time, you can just use methods below, which are built on top of Dojo Animation.

Note: one interesting method from Dojo that could be useful from time to time is "Dojo.Animation". It allows you to make any CSS property "slide" from one value to another.

Note 2: the slideTo methods are not compatible with CSS transform (scale, zoom, rotate...). If possible, avoid using CSS transform on nodes that are being slided. Eventually, the only possible solution to make these 2 compatible is to disable all CSS transform properties, use slideToObjectPos/placeOnObjectPos, and then apply them again.

'''this.slideToObject( mobile_obj, target_obj, duration, delay )'''

You can use slideToObject to "slide" an element to a target position.

Sliding element on the game area is the recommended and the most used way to animate your game interface. Using slides allow players to figure out what is happening on the game, as if they were playing with the real boardgame.

The parameters are:
* mobile_obj: the ID of the object to move. This object must be "relative" or "absolute" positioned.
* target_obj: the ID of the target object. This object must be "relative" or "absolute" positioned. Note that it is not mandatory that mobile_obj and target_obj have the same size. If their size are different, the system slides the center of mobile_obj to the center of target_obj.
* duration: (optional) defines the duration in millisecond of the slide. The default is 500 milliseconds.
* delay: (optional). If you defines a delay, the slide will start only after this delay. This is particularly useful when you want to slide several object from the same position to the same position: you can give a 0ms delay to the first object, a 100ms delay to the second one, a 200ms delay to the third one, ... this way they won't be superposed during the slide.

BE CAREFUL: The method returns an dojo.fx animation, so you can combine it with other animation if you want to. It means that you have to call the "play()" method, otherwise the animation WON'T START.

Example:
<pre>
this.slideToObject( "some_token", "some_place_on_board" ).play();
</pre>

'''this.slideToObjectPos( mobile_obj, target_obj, target_x, target_y, duration, delay )'''

This method does exactly the same as "slideToObject", except than you can specify some (x,y) coordinates. This way, "mobile_obj" will slide to the specified x,y position relatively to "target_obj".

Example: slide a token to some place on the board, 10 pixels to the bottom:
<pre>
this.slideToObjectPos( "some_token", "some_place_on_board", 0, 10 ).play();
</pre>

'''this.slideTemporaryObject( mobile_obj_html, mobile_obj_parent, from, to, duration, delay )'''

This method is useful when you want to slide a temporary HTML object from one place to another. As this object does not exists before the animation and won't remain after, it could be complex to create this object (with dojo.place), to place it at its origin (with placeOnObject) to slide it (with slideToObject) and to make it disappear at the end.

slideTemporaryObject does all of this for you:
* mobile_obj_html is a piece of HTML code that represent the object to slide.
* mobile_obj_parent is the ID of an HTML element of your interface that will be the parent of this temporary HTML object.
* from is the ID of the origin of the slide.
* to is the ID of the target of the slide.
* duration/delay works exactly like in "slideToObject"

Example:
<pre>
this.slideTemporaryObject( '<div class="token_icon"></div>', 'tokens', 'my_origin_div', 'my_target_div' );
</pre>

'''this.slideToObjectAndDestroy: function( node, to, time, delay )'''

This method is a handy shortcut to slide an existing HTML object to some place then destroy it upon arrival. It can be used for example to move a victory token or a card from the board to the player panel to show that the player earns it, then destroy it when we don't need to keep it visible on the player panel.

It works the same as this.slideToObject and takes the same arguments.

Example:
<pre>
this.slideToObjectAndDestroy( "some_token", "some_place_on_board", 1000, 0 );
</pre>

'''this.fadeOutAndDestroy( node, duration, delay )'''

This function fade out the target HTML node, then destroy it.

Example:
<pre>
this.fadeOutAndDestroy( "a_card_that_must_disappear" );
</pre>

CAREFUL: the HTML node still exists until during few milliseconds, until the fadeOut has been completed.

'''Rotating elements'''

You can check here [http://jimfulton.info/demos/dojo-animated-rotate.html an example of use] of Dojo to make an element rotate.

This example combines "Dojo.Animation" method and a CSS3 property that allow you to rotate the element.

IMPORTANT: to asses browser compatibility, you must select the CSS property to use just like in the example (see sourcecode below):

<pre>
var transform;
dojo.forEach(
['transform', 'WebkitTransform', 'msTransform',
'MozTransform', 'OTransform'],
function (name) {
if (typeof dojo.body().style[name] != 'undefined') {
transform = name;
}
});
// ... and then use "transform" as the name of your CSS property for rotation
</pre>

'''Animation Callbacks'''

If you wish to run some code only after an animation has completed you can do this by linking a callback method.

<pre>
var animation_id = this.slideToObject( mobile_obj, target_obj, duration, delay );
dojo.connect(animation_id, 'onEnd', dojo.hitch(this, 'callback_function', parameters));
animation_id.play();

…

callback_function: function(params) {
// this will be called after the animation ends
},
</pre>

If you wish to call a second animation after the first (rather than general code) then you can use a dojo animation chain (see tutorial referenced above).

=== Moving elements ===

'''this.placeOnObject( mobile_obj, target_obj )'''

placeOnObject works exactly like "slideToObject", except that the effect is immediate.

This is not really an animation, but placeOnObject is frequently used before starting an animation.

Example:
<pre>
// (We just created an object "my_new_token")

// Place the new token on current player board
this.placeOnObject( "my_new_token", "overall_player_board_"+this.player_id );

// Then slide it to its position on the board
this.slideToObject( "my_new_token", "a_place_on_board" ).play();
</pre>

'''this.placeOnObjectPos( mobile_obj, target_obj, target_x, target_y )'''

This method works exactly like placeOnObject, except than you can specify some (x,y) coordinates. This way, "mobile_obj" will be placed to the specified x,y position relatively to "target_obj".

'''this.attachToNewParent( mobile_obj, target_obj )'''

With this method, you change the HTML parent of "mobile_obj" element. "target_obj" is the new parent of this element. The beauty of
attachToNewParent is that the mobile_obj element DOES NOT MOVE during this process.

Note: what happens is that the method calculate a relative position of mobile_obj to make sure it does not move after the HTML parent changes.

Why using this method?

Changing the HTML parent of an element can be useful for the following reasons:
* When the HTML parent moves, all its child are moving with them. If some game elements is no more linked with a parent HTML object, you may want to attach it to another place.
* The z_order (vertical order of display) depends on the position in the DOM, so you may need to change the parent of some game elements when they are moving in your game area.

CAREFUL: this function destroys original object and places a clone onto a new parent, this will break all references to this HTML element (ex: dojo.connect).

== Players input ==

'''dojo.connect'''

Used to associate a player event with one of your notification method.

Example: associate a click on an element ("my_element") with one of our method ("onClickOnMyElement"):
<pre>
dojo.connect( $('my_element'), 'onclick', this, 'onClickOnMyElement' );
</pre>

Note: this is the only possible correct way to associate a player input event to your code, and you must not use anything else.

'''this.checkAction( "my_action_name" )'''

Usage: checkAction: function( action, nomessage )

Check if player can do the specified action by taking into account:
* current game state
* interface locking (a player can't do any action if an action is already in progress)

Restricted arguments names (please don't use them):

* "action"
* "module"
* "class"
return true if action is authorized (ie: the action is listed as a "possibleaction" in current game state).

return false and display an error message if not (display no message if nomessage parameter is true). The displayed error message could be either "This move is not allowed at this moment" or "An action is already in progress".

Example:
<pre>
function onClickOnGameElement( evt )
{
if( this.checkAction( "my_action" ) )
{
// Do the action
}
}
</pre>

'''this.checkPossibleActions( "my_action_name" )'''

Usage: checkPossibleActions: function( action, nomessage )

* this is independent of the player being active, so can be used instead of this.checkAction(). This is particularly useful for multiplayer states when the player is not active in a 'player may like to change their mind' scenario.

Check if player can do the specified action by taking into account:
* current game state
* interface locking (a player can't do any action if an action is already in progress)

Restricted arguments names (please don't use them):
* "action"
* "module"
* "class"

'''this.ajaxcall( url, parameters, obj_callback, callback, callback_error )'''

This method must be used to send a player input to the game server.

* url: the url of the action to perform. For a game, it must be: "/<mygame>/<mygame>/myAction.html"
* parameters: an array of parameter to send to the game server. Note that "lock:true" must always be specified in this list of parameter in order the interface can be locked during the server call.
* obj_callback: must be set to "this".
* callback: a function to trigger when the server returns and everything went fine.
* callback_error: (optional and rarely used) a function to trigger when the server returns an error. if no error this function is called with parameter value false.

Usage:
<pre>
this.ajaxcall( '/mygame/mygame/myaction.html', { lock: true,
arg1: myarg1,
arg2: myarg2,
...
}, this, function( result ) {
// Do some stuff after a successful call
} );
</pre>

'''this.confirmationDialog()'''

Display a confirmation dialog with a yes/no choice.

We advice you to NOT use this function unless the player action is really critical and could ruins the game, because it slows down the game and upset players.

Usage: this.confirmationDialog( "Question to displayed", callback_function_if_click_on_yes );

Example:
<pre>
this.confirmationDialog( _('Are you sure to use this bonus (points penalty at the end of the game) ?'),
dojo.hitch( this, function() {
this.ajaxcall( '/seasons/seasons/useBonus.html',
{ id:bonus_id, lock:true }, this, function( result ) {} );
} ) );
</pre>

; addEventToClass: function( cssClassName, eventName, functionName )
: Same as dojo.connect(), but for all the nodes set with the specified cssClassName

'''this.addActionButton( id, label, method, (opt)destination, (opt)blinking, (opt)color )'''

You can use this method to add an action button in the main action status bar.

Arguments:
* id: an element ID that should be unique in your HTML DOM document.
* label: the text of the button. Should be translatable (use _() function).
* method: the name of your method that must be triggered when the player clicks on this button.
* destination (optional): deprecated, do not use this. Use '''null''' as value if you need to specify other arguments.
* blinking (optional): if set to '''true''', the button is going blink to catch player's attention. Please don't abuse of blinking button.
* color: could be '''blue''' (default), '''red''' or '''gray'''.

You should only use this method in your "onUpdateActionButtons" method. Usually, you use it like this (from Hearts example):

<pre>
onUpdateActionButtons: function( stateName, args ) {

if (this.isCurrentPlayerActive()) {
switch( stateName ) {
case 'giveCards':
this.addActionButton( 'giveCards_button', _('Give selected cards'), 'onGiveCards' );
break;
}
}
},
</pre>

In the example above, we are adding a "Give selected cards" button in the case we are on game state "giveCards". When player clicks on this button, it triggers our "onGiveCards" method.

Example using blinking red button:
<pre>
this.addActionButton( 'commit_button', _('Confirm'), 'onConfirm', null, true, 'red');
</pre>

Note: at least in studio example above will make button huge, because it sets it display of blinking things to '''block''',
if you don't like it you have to change css display value
of the button to inline-block (the id of the button is the first argument, i.e 'commit_button' in example above)

== Translations ==

See [[Translations]]

== Notifications ==

When something happens on the server side, your game interface Javascript logic received a notification.

Here's how you can handle these notifications on the client side.

=== Subscribe to notifications ===

Your Javascript "setupNotifications" method is the place where you can subscribe to notifications from your PHP code.

Here's how you associate one of your Javascript method to a notification "playDisc" (from Reversi example):

<pre>
// In setupNotifications method:
dojo.subscribe( 'playDisc', this, "notif_playDisc" );
</pre>

Note: the "playDisc" corresponds to the name of the notification you define it in your PHP code, in your "notifyAllPlayers" or "notifyPlayer" method.

Then, you have to define your "notif_playDisc" method:

<pre>
notif_playDisc: function( notif )
{
// Remove current possible moves (makes the board more clear)
dojo.query( '.possibleMove' ).removeClass( 'possibleMove' );

this.addDiscOnBoard( notif.args.x, notif.args.y, notif.args.player_id );
},
</pre>

In a notification handler like our "notif_playDisc" method, you can access to all notifications arguments with "notif.args".

Example:
<pre>
// If you did this on PHP side:
self::notifyAllPlayers( "myNotification", '', array( "myArgument" => 3 ) );

// On Javascript side, you can access the "myArgument" like this:
notif_myNotification: function( notif )
{
alert( "myArgument = " + notif.args.myArgument );
}
</pre>

=== Synchronous notifications ===

When several notifications are received by your game interface, these notifications are processed immediately, one after the other, in the same exact order they have been generated in your PHP game logic.

However, sometimes, you need to give some time to the players to figure out what happened on the game before jumping to the next notification. Indeed, in many games, they are a lot of automatic actions, and the computer is going to resolve all these actions very fast if you don't tell it not to do so.

As an example, for Reversi, when someone is playing a disc, we want to wait 500 milliseconds before doing anything else in order the opponent player can figure out what move has been played.

Here's how we do this, right after our subscription:
<pre>
dojo.subscribe( 'playDisc', this, "notif_playDisc" );
this.notifqueue.setSynchronous( 'playDisc', 500 ); // Wait 500 milliseconds after executing the playDisc handler
</pre>

=== Pre-defined notification types ===

'''tableWindow''' - This defines notification to display [[Game_interface_logic:_yourgamename.js#Scoring_dialogs|Scoring Dialogs]], see below.

'''message''' - This defines notification that shows on players log and have no other effect

// You can call this on php side without doing anything on client side
self::notifyAllPlayers( 'message', 'hello', array( ) );

== Tooltips ==

'''this.addTooltip( nodeId, _( helpString ), _( actionString ), delay )'''

Add a simple text tooltip to the DOM node.

Specify 'helpString' to display some information about "what is this game element?".
Specify 'actionString' to display some information about "what happens when I click on this element?".

You must specify both helpString and actionString. Most of the time, you should use only one and specify a void string ("") for the other one.

Usually, _() must be used for the text to be marked for translation.

"Delay" is an optional parameter. Usually, it is primarily used to specify a zero delay for some game element when the tooltip gives really important information for the game - but remember: no essential information must be placed in tooltips as they won't be displayed in some browsers (see [[BGA_Studio_Guidelines|Guidelines]]).

Example:
<pre>
this.addTooltip( 'cardcount', _('Number of cards in hand'), '' );
</pre>

'''this.addTooltipHtml( nodeId, html, delay )'''

Add an HTML tooltip to the DOM node (for more elaborate content such as presenting a bigger version of a card).

'''this.addTooltipToClass( cssClass, _( helpString ), _( actionString ), delay )'''

Add a simple text tooltip to all the DOM nodes set with this cssClass.

IMPORTANT: all concerned nodes must have IDs to get tooltips.

'''this.addTooltipHtmlToClass( cssClass, html, delay )'''

Add an HTML tooltip to to all the DOM nodes set with this cssClass (for more elaborate content such as presenting a bigger version of a card).

IMPORTANT: all concerned nodes must have IDs to get tooltips

'''this.removeTooltip( nodeId )'''

Remove a tooltip from the DOM node.

== Dialogs, warning messages, confirmation dialogs, ... ==

=== Warning messages ===

Sometimes, there is something important that is happening on the game and you have to make sure all players get the message. Most of the time, the evolution of the game situation or the game log is enough, but sometimes you need something more visible.

Ex: someone fulfill one of the end of the game condition, so this is the last turn.

'''this.showMessage( msg, type )'''

showMessage shows a message in a big rectangular area on the top of the screen of current player.

* "msg" is the string to display. It should be translated.
* "type" can be set to "info" or "error". If set to "info", the message will be an informative message on a white background. If set to "error", the message will be an error message on a red background.

Important: the normal way to inform players about the progression of the game is the game log. "showMessage" is intrusive and should not be used often.

=== Confirmation dialog ===

'''confirmationDialog( message, yesHandler, noHandler )'''

When an important action with a lot of consequences is triggered by the player, you may want to propose a confirmation dialog.

CAREFUL: the general guidelines of BGA is to AVOID the use of confirmation dialog. Confirmation dialogs slow down the game and bother players. The players knows that they have to pay attention about each move when they are playing online.

The situation where you should use a confirmation dialog are the following:
* It must not happen very often during a game.
* It must be linked to an action that can really "kill a game" if the player do not pay attention.
* It must be something that can be done by mistake (ex: a link on the action status bar).

How to display a confirmation dialog:
<pre>
this.confirmationDialog( _('Are you sure you want to bake the pie?'), dojo.hitch( this, function() {
this.bakeThePie();
} ) );
return; // nothing should be called or done after calling this, all action must be done in the handler
</pre>

=== Multiple choice dialog ===
You can use this dialog to give user a choice with small amount of options:
<pre>
var keys = [1,5,10];
this.multipleChoiceDialog(
_('How many bugs to fix?'), keys,
dojo.hitch(this, function(choice) {
var bugchoice = keys[choice];
console.log('dialog callback with '+bugchoice);
this.ajaxcall( '/mygame/mygame/fixBugs.html', { bugs: bugchoice}, this, function( result ) {} ); }));
</pre>

=== Dialogs ===

As a general rule, you shouldn't use dialogs windows.

BGA guidelines specify that all game elements should be displayed on the main screen. Players can eventually scroll down to see game elements they don't need to see anytime, and you may eventually create anchors to move between game area section. Of course dialogs windows are very practical, but the thing is: all players know how to scroll down, and not all players know how to show up your dialog window. In addition, when the dialog shows up, players can't access the other game components.

Sometimes although, you need to display a dialog window. Here is how you do this:

// Create the new dialog over the play zone. You should store the handler in a member variable to access it later
this.myDlg = new ebg.popindialog();
this.myDlg.create( 'myDialogUniqueId' );
this.myDlg.setTitle( _("my dialog title to translate") );
this.myDlg.setMaxWidth( 500 ); // Optional

// Create the HTML of my dialog.
// The best practice here is to use [[Game_layout:_view_and_template:_yourgamename.view.php_and_yourgamename_yourgamename.tpl#Javascript_templates|Javascript templates]]
var html = this.format_block( 'jstpl_myDialogTemplate', {
arg1: myArg1,
arg2: myArg2,
...
} );

// Show the dialog
this.myDlg.setContent( html ); // Must be set before calling show() so that the size of the content is defined before positioning the dialog
this.myDlg.show();

// Now that the dialog has been displayed, you can connect your method to some dialog elements
// Example, if you have an "OK" button in the HTML of your dialog:
dojo.connect( $('my_ok_button'), 'onclick', this, function(evt){
evt.preventDefault();
this.myDlg.destroy();
} );

If necessary, you can remove the default top right corner 'close' icon, or replace the function called when it is clicked:
// Removes the default close icon
this.myDlg.hideCloseIcon();

// Replace the function call when it's clicked
this.myDlg.replaceQuitCallback( function() { ... } );

=== Scoring dialogs ===

Sometimes at the end of a round you want to display a big table that details the points wins in each section of the game.

Example: in Hearts game, we display at the end of each round the number of "heart" cards collected by each player, the player who collected the Queen of Spades, and the total number of points loose by each player.

Scoring dialogs are managed entirely on '''PHP side''', but they are described here as their effects are visible only on client side.

Displaying a scoring dialog is quite simple and is using a special notification type: "tableWindow":
<pre>
// on PHP side:
$this->notifyAllPlayers( "tableWindow", '', array(
"id" => 'finalScoring',
"title" => clienttranslate("Title of the scoring dialog"),
"table" => $table
) );
</pre>

The "table" argument is a 2 dimensional PHP array that describe the table you want to display, line by line and column by column.

Example: display an 3x3 array of strings
<pre>
$table = array(
array( "one", "two", "three" ), // This is my first line
array( "four", "five", "six" ), // This is my second line
array( "seven", "height", "nine" ) // This is my third line
);
</pre>

As you can see above, in each "cell" of your array you can display a simple string value. But you can also display a complex value with a template and associated arguments like this:
<pre>
$table = array(
array( "one", "two", array( "str" => clienttranslate("a string with an ${argument}"), "args" => array( 'argument' => 'argument_value' ) ) ),
array( "four", "five", "six" ),
array( "seven", "height", "nine" )
);
</pre>

This is especially useful when you want to display player names with colors. Example from "Hearts":
<pre>
$firstRow = array( '' );
foreach( $players as $player_id => $player )
{
$firstRow[] = array( 'str' => '${player_name}',
'args' => array( 'player_name' => $player['player_name'] ),
'type' => 'header'
);
}
$table[] = $firstRow;
</pre>

You can also use three extra attributes in the parameter array for the notification:

<pre>
$this->notifyAllPlayers( "tableWindow", '', array(
"id" => 'finalScoring',
"title" => clienttranslate("Title of the scoring dialog"),
"table" => $table,
"header" => array('str' => clienttranslate('Table header with parameter ${number}'),
'args' => array( 'number' => 3 ),
),
"footer" => '<div>Some footer</div>',
"closing" => clienttranslate( "Closing button label" )
) );
</pre>

*'''header''': the content for this parameter will display before the table (also, the html will be parsed and player names will be colored according to the current game colors).
*'''footer''': the content for this parameter will display after the table (no parsing for coloring the player names)
*'''closing''': if this parameter is used, a button will be displayed with this label at the bottom of the popup and will allow players to close it (more easily than by clicking the top right 'cross' icon).

=== Scoring animated display ===

Sometimes (Terra Mystica final scoring for example), you may want to display a score value over an element to make the scoring easier to follow for the players.
You can do it with:

<pre>
this.displayScoring( anchor_id, color, score, duration );
</pre>

'''anchor_id''': ID of the element to place the animated score onto (without the '#')

'''color''': hexadecimal RGB representation of the color (should be the color of the scoring player), but without a leading '#'. For instance, 'ff0000' for red.

'''score''': numeric score to display, prefixed by a '+'

'''duration''': animation duration in milliseconds

Note: if you want to display successively each score, you can use ''this.notifqueue.setSynchronous()'' function.

=== Speech bubble ===

For better interactivity in some games (Love Letter for example), you may use comic book style speech bubbles to express the players voices.
This is done with:

<pre>
this.showBubble( anchor_id, text, delay, duration, custom_class )
</pre>

delay in milliseconds is optional (default 0)

duration in milliseconds is optional (default 3000)

custom_class is optional, if you need to override the default bubble style

'''Warning''': if your bubble could overlap other active elements of the interface (buttons in particular), as it stays in place even after disappearing, you should use a custom class to give it the style "pointer-events: none;" in order to intercept click events.

== Update players score ==

The column player_score from the player table is automatically loaded into this.scoreCtrl and therefore into the stars location on the player board. This occurs sometime after the <gamename>.js setup() function. However this score must be updated as the game progresses through player notifications (notifs).

Increase a player score (with a positive or negative number):

<pre>
this.scoreCtrl[ player_id ].incValue( score_delta );
</pre>

Set a player score to a specific value:

<pre>
this.scoreCtrl[ player_id ].setValue( new_score );
</pre>

Set a player score to a specific value with animation :

<pre>
this.scoreCtrl[ player_id ].toValue( new_score );
</pre>

== Players panels ==

=== Adding stuff to player's panel ===

At first, create a new "JS template" string in your template (tpl) file:

(from Gomoku example)
<pre>
var jstpl_player_board = '\<div class="cp_board">\
<div id="stoneicon_p${id}" class="gmk_stoneicon gmk_stoneicon_${color}"></div><span id="stonecount_p${id}">0</span>\
</div>';
</pre>

Then, you add this piece of code in your JS file to add this template to each player panel:

<pre>
// Setting up player boards
for( var player_id in gamedatas.players )
{
var player = gamedatas.players[player_id];

// Setting up players boards if needed
var player_board_div = $('player_board_'+player_id);
dojo.place( this.format_block('jstpl_player_board', player ), player_board_div );
}
</pre>

(Note: the code above is of course from your "setup" function in your Javascript).

Very often, you have to distinguish current player and others players. In this case, you just have to create another JS template (ex: jstpl_otherplayer_board) and use it when "player_id" is different than "this.player_id".

=== Player's panel disabling/enabling ===

'''this.disablePlayerPanel( player_id )'''

Disable given player panel (the panel background become gray).

Usually, this is used to signal that this played passes, or will be inactive during a while.

Note that the only effect of this is visual. There are no consequences on the behaviour of the panel itself.

'''this.enablePlayerPanel( player_id )'''

Enable a player panel that has been disabled before.

'''this.enableAllPlayerPanels()'''

Enable all player panels that has been disabled before.

== Image loading ==

See also [[Game_art:_img_directory]].

'''Be careful''': by default, ALL images of your img directory are loaded on a player's browser when he loads the game. For this reason, don't let in your img directory images that are not useful, otherwise it's going to slowdown the game load.

'''dontPreloadImage( image_file_name )'''

Using dontPreloadImage, you tell the interface to not preload a specific image in your img directory.

Example of use:
<pre>
this.dontPreloadImage( 'cards.png' );
</pre>

This is particularly useful if for example you have 2 different themes for a game. To accelerate the loading of the game, you can specify to not preload images corresponding to the other theme.

Another example of use: in "Gosu" game with Kamakor extension, you play with 5 sets of cards among 10 available. Cards images are organized by sets, and we only preload the images corresponding to the 5 current sets with '''ensureSpecificGameImageLoading( image_file_names_array )'''.
<pre>
// By default, do not preload anything
this.dontPreloadImage( 'cards.png' );
this.dontPreloadImage( 'clan1.png' );
this.dontPreloadImage( 'clan2.png' );
this.dontPreloadImage( 'clan3.png' );
this.dontPreloadImage( 'clan4.png' );
this.dontPreloadImage( 'clan5.png' );
this.dontPreloadImage( 'clan6.png' );
this.dontPreloadImage( 'clan7.png' );
this.dontPreloadImage( 'clan8.png' );
this.dontPreloadImage( 'clan9.png' );
this.dontPreloadImage( 'clan10.png' );
var to_preload = [];
for( i in this.gamedatas.clans )
{
var clan_id = this.gamedatas.clans[i];
to_preload.push( 'clan'+clan_id+'.png' );
}
if( to_preload.length == 5 )
{
this.ensureSpecificGameImageLoading( to_preload );
}
</pre>

'''Note:''' You don't need to specify to not preload game box images (game_box.png, game_box75.png...) since they are not preloaded by default.

== Other useful stuff ==

'''dojo.hitch'''

With dojo.hitch, you can create a callback function that will run with your game object context whatever happen.

Typical example: display a BGA confirmation dialog with a callback function created with dojo.hitch:

<pre>
this.confirmationDialog( _('Are you sure you want to make this?'), dojo.hitch( this, function() {
this.ajaxcall( '/mygame/mygame/makeThis.html', { lock:true }, this, function( result ) {} );
} ) );
</pre>

In the example above, using dojo.hitch, we ensure that the "this" object will be set when the callback is called.

; updateCounters(counters)
: Useful for updating game counters in the player panel (such as resources).
: 'counters' arg is an associative array [counter_name_value => [ 'counter_name' => counter_name_value, 'counter_value' => counter_value_value], ... ]
: All counters must be referenced in this.gamedatas.counters and will be updated.
: DOM objects referenced by 'counter_name' will have their innerHTML updated with 'counter_value'.

'''onScreenWidthChange()'''
This function can be overridden in your game to manage some resizing on the client side when the browser window is resized. This function is also triggered at load time, so it can be used to adapt to the viewport size at the start of the game too.

'''updatePageTitle()'''
This function allows to update the current page title and turn description according to the game state. If the current game state description this.gamedatas.gamestate.descriptionmyturn is modified before calling the function, it allows to update the turn description without changing state.

Example from Terra Mystica:
<pre>
onClickFavorTile: function( evt )
{
[...]

if ( ... ) {

this.gamedatas.gamestate.descriptionmyturn = _('Special action: ') + _('Advance 1 space on a Cult track');
this.updatePageTitle();
this.removeActionButtons();

this.addActionButton( 'action_confirm1', _("Fire"),
function() { ... }
);
this.addActionButton( 'action_confirm2', _("Water"),
function() { ... }
);
this.addActionButton( 'action_confirm3', _("Earth"),
function() { ... }
);
this.addActionButton( 'action_confirm4', _("Air"),
function() { ... }
);

this.addActionButton( 'action_cancel', _("Cancel"), function() { ... }, false, false, 'gray'
);

return;
}

[...]

}
</pre>

== BGA GUI components ==

BGA framework provides some useful ready-to-use components for the game interface:

[[Studio#BGA_Studio_game_components_reference]]

Note that each time you are using an additional component, you must declare it at the top of your Javascript file in the list of modules used.

Example if you are using "ebg.stock":
<pre>
define([
"dojo","dojo/_base/declare",
"ebg/core/gamegui",
"ebg/counter",
"ebg/stock" /// <=== we are using ebg.stock module
],
</pre>

== Sounds ==

Add a custom sound and make it load with your interface:

Add this in your template (.tpl) file:
<pre>
<audio id="audiosrc_<gamename>_<yoursoundname>" src="{GAMETHEMEURL}img/<filename>.mp3" preload="none" autobuffer></audio>
<audio id="audiosrc_o_<gamename>_<yoursoundname>" src="{GAMETHEMEURL}img/<filename>.ogg" preload="none" autobuffer></audio>
</pre>

Note: this is a requirement to provide both a mp3 and a ogg file.

Play the sound (from your .js file):

<pre>
playSound('<gamename>_<yoursoundname>');
</pre>

Disable the standard "move" sound for this move (to replace it with your custom sound):

Add this to your notification handler:

<pre>
this.disableNextMoveSound();
</pre>

Note: it only disable the sound for the next move.

Tools and tips of BGA Studio

2020-08-18T21:05:24Z

Pickardj79:

{{Studio_Framework_Navigation}}

== Server Tools and Tips ==
=== Starting a game in one click ===

To start a game:
* Go to Play now and configure game type: Simple game -> Turn-based -> Manual
* Select your game and click on "Create".
* If you want to play a game with 3 players, specify that you want a maximum of 3 players at this table.
* Click on "Express Start".

=== Stopping a game in one click ===

* Click on the "quit" icon on the top right of the screen.
* Click on "Express Stop".

=== Switching between users ===

When running a game on Studio, you can use the little red arrow near each player's name to open a new tab with this player's perspective.

=== Access to game database and Logs ===

At the bottom of the game area, there is section without a title containing 3 useful links:

Go to game database • BGA request&SQL logs • BGA unexpected exceptions logs

* "Go to game database" link is an immediate access to the PhpMyAdmin tool to view/edit the tables of the current game
* BGA request&SQL logs - link to your studio PHP log - all tables, all severities. Anything you print using debugging and tracing functions from PHP and some framework logs
* BGA unexpected exceptions logs - same log as above but only severity warning and higher

See [[Practical debugging]] for more info about it.

=== Save & restore state ===

Using links of this section, you can save the complete current (database) state of your game, then restore it later.

This is particularly useful when you want to develop a part of the game that is difficult to reproduce: you just have to save the situation just before, and then restore it until this part works fine.

We provide you 3 "slots": 1, 2 and 3. This way, you can save 3 different game situations.

Limits:
* the "restore" function does not work anymore when the game is over.
* a saved situation from a given table cannot be restored in another table.
* when you "restore" a situation, the current browser page is refreshed to reflect the updated game situation, but you have to refresh you other tabs/pages manually.

=== Input/Output debugging section ===

This section shows you:
* The AJAX calls made by your game interface to the game server. AJAX calls (outputs) begins with ">"
* The notifications received by your game interface. Notifications (inputs) begins with "<".

Note: if you click on some notification title, you can resend it immediately to the user interface.

=== Run PHP functions from the chat ===

On BGA Studio, you can directly run a PHP method from the table chat.

For example, if on your PHP you have this method:

function giveMoneyToPlayer($player_id, $amount) { ... }

You can call this method directly from the chat like this:

giveMoneyToPlayer(2564,2)

Note: this is not a real php statement, you cannot use self::, you cannot use ";" at the end and you cannot use quotes,
if you need to pass a string skip the quotes, like this

giveToActivePlayer(money,2)

=== Stopping Hanging Game ===

If game is hanging and you cannot enter it to stop you can type this URL (replace 12345 with your table number),
which should bring you to a place where you can stop it without entering:

<nowiki>http://en.studio.boardgamearena.com/#!table?table=12345</nowiki>

== Desktop and Web Tools ==
=== Code Editors and IDEs ===
==== Eclipse For PHP Developers ====

Eclipse PHP package can be starting point for development you need. You may also want to
install Tern JS plugins to understand dojo style JS. All desktops.
https://projects.eclipse.org/projects/tools.pdt

==== Visual Studio Code ====

Microsoft Visual Studio Code is light weight IDE/Editor. All desktops.
https://code.visualstudio.com

==== Gedit (Ubuntu) ====
'''Edit TPL'''
To edit TPL with HTML code highlightings in Gedit under Ubuntu:

find gtksourceview directory in /usr/share, depending on your version (2.0, 3.0,...).
<br>
Here it's 3.0, then type in a terminal window:
<pre>
sudo gedit /usr/share/gtksourceview-3.0/language-specs/html.lang
</pre>

then find 'globs' section, and change:

<pre>
<property name="globs">*.html;*.htm;*.tpl</property>
</pre>

=== File Sync ===

==== File Sync on Windows ====

Install [http://winscp.net/ WinSCP]. Map a remote directory to a local one and enable continuous sync (one way). You need SFTP password you get when you registered dev account.

==== File Sync on Linux ====

===== Option 1 - Nautilus (file manager) =====
You can just use Nautilus "connect to a server" function with URL sftp://1.studio.boardgamearena.com
Then you'll get a mounted local folder mapping your studio folder and you can use any editor you like without further need for sync. Downside - if connection goes down you cannot work on source code, no local copy.

===== Option 2 - sftp and rsync =====
<pre>
#!/bin/bash
BASEDIR=`dirname $0`
REMOTE=$BASEDIR/remote
LOCAL=$BASEDIR/workspace
GAME=mygamenamehere

#mount remote
fusermount -u $REMOTE #this unmounts dir
echo LongDevPassword | sshfs -o password_stdin myusernamehere@1.studio.boardgamearena.com: $REMOTE

#this starts auto-sync from local to remote mount
killall lsyncd
lsyncd -delay 1 -rsync $LOCAL/$GAME/ $REMOTE/$GAME
</pre>

This can be able run on startup, so you don't have to do anything manually. However sshfs is not very stable you
have to kill and restart it sometimes. And remote goes away sometimes due to connection issues with studio.
In this case its handy to have a local copy, which is what lsyncd for.

You can also sync on demand (from a build script or editor command) using
rsync -vlrt $LOCAL/$GAME/ $REMOTE/$GAME

===== Option 3 - lftp =====

[https://lftp.yar.ru/ lftp] is a fast command-line file transfer program. It's a much better choice than rsync for BGA Studio since it supports parallel threads, transferring multiple files at a time.

* Linux: Install using your package manager, for example: '''sudo apt-get install lftp'''
* Mac: Install [https://brew.sh/ Homebrew], then install lftp using '''brew install lftp'''

To upload your project to BGA studio, use the "mirror" command like this:

'''lftp sftp://<span style="color:blue">myuser</span>:<span style="color:red">mypassword</span>@1.studio.boardgamearena.com/ -e "mirror --reverse --parallel=10 --delete <span style="color:orange">/local/path/to/myproject</span>/ <span style="color:green">myproject</span>/; exit"

Be sure to include the trailing '''/''' after both directory names.

By default, if a file already exists on BGA Studio with the same time + size it assumed to be the same and won't be transferred. This makes the transfer process much quicker after the first time. If you're working with multiple developers on the same project and you find that it is transfers all files every time, you may want to add the option '''--ignore-time''' (if a file already exist on BGA Studio with the same size it is assumed to be the same and won't be transferred). Read [https://lftp.yar.ru/lftp-man.html the manual] for more details.

==== File Sync using VSCode ====
You might rely on your IDE to sync the files with the SFTP server. Each time you "save" a file with your modifications, the IDE will also submit it to the sFTP server. These are instructions for VS Code

* '''Install this extension''' https://marketplace.visualstudio.com/items?itemName=liximomo.sftp (File->Preferences->Extensions ... type SFTP and Install)

* '''Open VSCode on an empty folder''' that will be the local root of your project.

* Execute Ctrl+Shift+P on Windows/Linux or Cmd+Shift+P on Mac to open the command palette, and the type/run : '''"SFTP: config"''' - the edit will open with json config

* '''Update the json''' as below:

<pre>
{
"name": "BGA",
"host": "1.studio.boardgamearena.com",
"protocol": "sftp",
"port": 22,
"username": "<your SFTP username>",
"password": "<your SFTP password>",
"remotePath": "/<your project name>/",
"uploadOnSave": true,
"ignore": [
".vscode",
".git",
".DS_Store"
]
}
</pre>

- Execute Ctrl+Shift+P on Windows/Linux or Cmd+Shift+P on Mac to open the command palette, and the type/run : '''"SFTP: Download Project"'''.

This will download all the files locally, and each time you modify/save a file in VSCode, it will upload it to the SFTP Server.

=== Debuggers ===

Browser is the best tool for JS/HTML5 debugging, see [[Practical debugging]] for details.

=== Version Control ===
Studio providers svn for you code on server, there are some limited abilities there to see history and restore. I recommend to keep your code in another repository. I suggest to use git with local repo, which you can sync to cloud or backup.
Other option is to host source code on github, if you do use this convention github.com/<yourname>/bga-<yourgame>. In such case make sure you '''don't post high-res publisher graphics''' only web resources, and post a separate license for graphics files. Also, '''don't include a file with your sftp password''' (github is automatically crawled for passwords by hackers; a hacking attempt occurred on BGA studio for this reason in June 2020).

=== PHP CLI ===
Its handy to have php cli (command line) tools install to run php locally, so you can test some stuff without deployment cycle, or create some scripts that generate code or markup.

=== Image Manipulation ===
==== ImageMagick ====
Handy set of image manipulation '''command line''' tools, useful to for example to stitch together bunch of images and re-size, to use as sprite (in Stock component for example). I.e. you got a graphics file from publisher where every tile is 600x600 PNG file in separate file. You want .jpg instead of .png to make it not like 20Mb, and combine all images in one column and re-size to 128x128:

(Linux example)
/usr/bin/montage `ls Tiles*.png` -tile 1 -geometry 128x128+0+0 out/tiles128.jpg

https://www.imagemagick.org/script/download.php

==== Gimp ====

GUI tool, very complex but will do ALL what you possibly need to do with game graphics

https://www.gimp.org/

==== Shrinking ====

Shrink images without loss of quality https://tinypng.com/ or http://www.iloveimg.com/

==== PDF Scrapper ====
extract images from PDF file (i.e. game rulebook) :

https://www.ilovepdf.com/

http://www.extractpdf.com/

==== Rename/Copy project ====

There is a script available in sharedcode project to do the renaming which can be called in command line if you have php command line installed.
You need to have php clt (command line interface) installed, then you can download script and run it.

https://github.com/elaskavaia/bga-sharedcode/blob/master/misc/bgaprojectrename.php

Usage:
php bgaprojectrename.php <originalProjectPath> <copyOfProjectRenamedPath>

Example on how to call it in command line if you project name is "heartsmyproject"

php7.0 git/bga-sharedcode/tools/bgaprojectrename.php remote/hearts/ remote/heartsmyproject/

==== BGA Workbench ====

PHP library providing tools to help manage BGA Studio projects including deployment and test utilities. https://github.com/danielholmes/bga-workbench

== Client Tips ==

=== Speed up game re-loading by disabling Input/Output debug section ===

Development UI have few sections for debugging only, such as 'Input/Output debugging section'. Loading this data will significantly slow down
your reload. I did some profiling and my reloading (i.e. F5) took 14 seconds, 12 of which it was dealing with loading this section.
If you not using it you can disable it. In your JavaScript code, in the begging of 'setup' method add this code

dojo.destroy('debug_output');

That should get rid of this section and overhead associated with loading it (it may have some other side-effects, I have not explored all of them)

=== Speed up CSS development and layout ===

Syncing files to server and refreshing is relative fast but still can take up to 20 seconds which is annoying.
If you working
a lot on css/images/layout you can speed it up by coping html in some state of the game to your local folder.
I.e. in your project folder create directory misc/ and save your html as misc/test.html and changing path to css to load from local disk (and it will load your images to from local disk as well).
I.e. find something like

<link rel="stylesheet" type="text/css" href="http://1.studio.boardgamearena.com:8081/data/themereleases/151226-1240/games/mygame/999999-9999/mygame.css"/>

and replace with
<link rel="stylesheet" type="text/css" href="../mygame.css"/>

You project structure will look like this

mygame
img/ <-- your images
mygame.css <-- your original css
...
misc/
test.html <-- your test html

It is a bit tricky to save html exact state, if you do save as it also pulls all resources sometimes.
