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.

Zombie crash at some states

I have programmed "zombiePass" in major states of my game Cacao.
But I some step of the game, a player quitting the game fires a crash :

Unexpected error: Propagating error from GS 1 (method: zombie): feException: More than one possible action at this state in /var/tournoi/release/tournoi-200730-1036-gs/www/game/module/table/gamestate.game.php:333
Folowed by this messace, twice :
Unexpected error: Can't manage zombie player in this game state (5)

I have coded a big trace in zombieTurn function :

CODE: Select all

    function zombieTurn( $state, $active_player ) {
		self::dump('========================= zombieTurn : state = ',$state);
		self::dump('========================= zombieTurn : active_player = ',$active_player);
    	$statename = $state['name'];
I don't find these traces in my BGA request & SQL logs.

This occurs :
  • when players can carry out jungle tiles action (the game is in "multipleactiveplayer");
  • when the leaving player must choose a jungle tile.
I don't understand how to manage this problem if it's occurs outside of my code ?!

Show current player's board at the top

I'm working on a game where each player has their own board. Does anyone have an example handy of how to set up the view so that each player sees their own board at the top? Games like Potion Explosion and 7 Wonders do this.

I'm not sure if there's a way to do this in view.php, or if I should just use javascript to bring the appropriate board into place after the game loads. Doing it on the PHP side seems preferable. Right now my approach is to pull out the current player id from the player list array, set up their board, then loop through the remaining players after the current player is set up.

I've put together a crude illustration of the layout I'm going for, where the top div contains the player area consisting of their personal board (blue rectangle) and shared board (purple rectangle, same for everyone), and the bottom div has smaller versions of each of the opponents' player boards.

Looking for Developer for two upcoming TMG titles (Terra Prime reboot, and Eminent Domain dice game)

I have art files for Eminent Domain Origins, a reboot of one of TMG's launch titles Terra Prime in the Eminent Domain universe, complete and ready to go, but it has not been sent to the printer yet.

I would love to see it implemented on BGA! Is anyone interested in taking that on?

Terra Prime on BGG: https://www.boardgamegeek.com/boardgame ... erra-prime

Also, I have an artist partially done with files for an Eminent Domain dice game (Eminent Domain: Chaos Theory). I would be happy to see that one debut on BGA as well!

Let me know if you're interested in either of these.

Thank you,
Seth Jaffee
