This page references useful server side and client side functions, so that nobody needs to reinvent the wheel (unless he wants to).
Server side (PHP functions)
APP_GameAction class (<gamename>.action.php)
- function isArg( $argName )
- Is this argument filled ?
- function getArg( $argName, $argType, $mandatory=false, $default=NULL, $argTypeDetails=array(), $bCanFail=false )
- Get script argument with the correct type
- bCanFail means than a validation failure is possible (user input)
- The main argType values are as follows.
define( 'AT_int', 0 ); // an integer define( 'AT_posint', 1 ); // a positive integer define( 'AT_float', 2 ); // a float define( 'AT_email', 3 ); // an email define( 'AT_url', 4 ); // a URL define( 'AT_bool', 5 ); // 1/0/true/false define( 'AT_enum', 6 ); // argTypeDetails list the possible values define( 'AT_alphanum', 7 ); // only 0-9a-zA-Z_ and space
Table class (<gamename>.game.php)
- function _( $text )
- Transparent function, used to mark strings to be translated on the server side (ex: error message)
- function clienttranslate( $string )
- Transparent function: used to mark string to be translated on client side (ex: notification message)
- function getPlayersNumber()
- Returns the number of players playing at the table
- function checkAction( $actionName, $bThrowException=true )
- Check if action is valid regarding current game state (exception if fails)
- if "bThrowException" is set to "false", the function return false in case of failure instead of throwing and exception
- function getActivePlayerId()
- Get the "active_player", whatever what is the current state type
- Note: it does NOT mean that this player is active right now, because state type could be "game" or "multiplayer"
- function getActivePlayerName()
- Get the "active_player" name
- function getCurrentPlayerId()
- Get the "current_player". The current player is the one from which the action originated. It is not always the active player.
- function getCurrentPlayerName()
- Get the "current_player" name
- function getCurrentPlayerColor()
- Get the "current_player" color
- function isCurrentPlayerZombie()
- Check the "current_player" zombie status
- function activeNextPlayer()
- Make the next player active
- function activePrevPlayer()
- Make the previous player active
- function giveExtraTime( $player_id, $specific_time=null )
- Give standard extra time to this player (standard extra time is a game option)
- function initStat( $table_or_player, $name, $value, $player_id=null )
- Create a statistic entry for the specified statistics with a default value
- In case of a "player" entry, if player_id is not specified, all players are set to the same value
- function setStat( $value, $name, $player_id = null )
- Set statistic value
- function incStat( $delta, $name, $player_id = null )
- Increment (or decrement) specified value
- function DbQuery( $sql )
- Executes sql query on the database
- function getCollectionFromDB( $sql, $bSingleValue=false )
- Returns an associative array of rows for the sql query. First column must be a primary or alternate key. The resulting collection can be empty.
- protected function getNonEmptyCollectionFromDB( $sql )
- Idem, but raise an exception if the collection is empty
- function getUniqueValueFromDB( $sql )
- Returns a unique value from DB or null if no value is found
- Raise an exception if more than 1 row is returned
- function getObjectFromDB( $sql )
- Returns one row for the sql query as an associative array or null if there is no result
- Raise an exception if the query return more than one row
- function getNonEmptyObjectFromDB( $sql )
- Idem, but raise an exception if the query doesn't return exactly one row
Exceptions you can throw
- throw new BgaUserException ( $error_message)
- Base class to notify a user error
- throw new BgaSystemException ( $error_message)
- Base class to notify a system exception. The message will be hidden from the user, but show in the logs. Use this if the message contains technical information.
- throw new BgaSystemVisibleException ( $error_message)
- Same as previous, except that the message is visible by the user. You can use this if the message is understandable by the user.

- this.isCurrentPlayerActive()
- this.checkAction( 'selectTokens' )
- this.showMessage( _('You must select at least two tokens'), 'error' );
- this.scoreCtrl[ notif.args.player_id ].incValue( notif.args.score_delta );
- this.updateCounters(notif.args.counters);
- this.ajaxcall( "/colorpop/colorpop/endgame.html", { }, this, function( result ) {} );
