BGA Studio documentation

BGA Studio Framework reference

This part of the documentation focuses on the development framework itself: functions and methods available to build your game.

File structure of a BGA game

Game logic (Server side)

Game interface (Client side)

Other components

BGA Studio game components reference

Game components are useful tools you can use in your game adaptations.

  • Deck: a PHP component to manage cards (deck, hands, picking cards, moving cards, shuffle deck, ...).
  • Counter: a JS component to manage a counter that can increase/decrease (ex: player's score).
  • Scrollmap: a JS component to manage a scrollable game area (useful when the game area can be infinite. Examples: Saboteur or Takenoko games).
  • Stock: a JS component to manage and display a set of game elements displayed at a position.
  • Zone: a JS component to manage a zone of the board where several game elements can come and leave, but should be well displayed together (See for example: token's places at Can't Stop).

Undocumented component (if somebody knows please help with docs)

  • Draggable: a JS component to manage drag'n'drop actions.
  • ExpandableSection: a JS component to manage a rectangular block of HTML than can be displayed/hidden.
  • Wrapper: a JS component to wrap a <div> element around its child, even if these elements are absolute positioned.

Issue with Stock layout and setOverlap first time only

In my game I present the deck to the player so they can choose a card

I use the following method to add the deck to the stock:

CODE: Select all

spreadDeck: function(cards, parent) {
	var stock = new ebg.stock();
	stock.create(this, $(parent), this.cardWidth, this.cardHeight);
	dojo.connect(stock, 'onChangeSelection', this, 'onDeckSelect');
	stock.image_items_per_row = 14;
	stock.setOverlap(20, 0);
	var counter = 0;
	for(let i in cards) {
		stock.addItemType(cards[i].id, counter++, g_gamethemeurl + 'img/cards.png', 13);
		stock.addToStockWithId(cards[i].id, cards[i].id);
It is called from the onEnterStage at the correct state

CODE: Select all

onEnteringState: function (stateName, args) {
	console.log('Entering state: ' + stateName);

	switch (stateName) {

		case 'cutCard':
			dojo.style('cutCard', 'display', 'none');
			this.spreadDeck(args.args.deck, 'fullDeck');
			dojo.style('fullDeck', 'display', 'inline-block');
		case 'dummmy':
The issue is the first time this happens, the cards are displayed vertically like so


for both players, after refreshing the browser while the game is in the cutCard state the cards are displayed horizontally with the correct overlap


From what I can tell the generated Css looks the same before and after the refresh except for the height of the parent div, which leads me to believe it is being calculated by either setOverlap or addToStockWithId

Parent Div:

Bug in proudction I can't reproduce in the studio

I have a bug in my game that happens once in a blue moon, so I can't reproduce it in development. But it's happening in production as the game is being played much. My question is if there is a way to access to self::trace and self::dump of production in order to find the *@#$ bug!

I'm turning crazy!
