Group trouble or Pixi?

Hi.

 

I use Phaser 1.1.3, and this code gives me this error:

Uncaught TypeError: Object TurnGroup has no method 'addChild' at line 10897

 

Here's the code:

<!DOCTYPE html><html lang="en" xmlns="http://www.w3.org/1999/xhtml"><head>    <meta charset="utf-8" />    <script src="js/phaser.min.js"></script></head><body><div id="gameContainer"></div><script type="text/javascript">SQ = {};SQ.Game = function(game) {    this.game = game;};SQ.Game.prototype = {    create: function() {        this.turn = new SQ.Turn(this);    }};SQ.Turn = function(sq_game) {    Phaser.Group.call(this, sq_game.game, 'TurnGroup', true);};SQ.Turn.prototype = Object.create(Phaser.Group.prototype);SQ.Turn.prototype.constructor = SQ.Turn;window.onload = function() {    var game = new Phaser.Game(288, 512, Phaser.CANVAS, 'gameContainer');    game.state.add('Game', SQ.Game);    game.state.start('Game');};</script></body></html>

Ok, that works. According to the documentation Phaser.Group accepts only 4 parameters. Is the 5th documented?

 

This one used to confuse me too, and I don't know the official reason why, but the 'this' parameter in the function param list below is part of what is required when calling the generic implementation.  It never makes it to Phaser.Group constructor.

Phaser.Group.call(this, sq_game.game, null, 'TurnGroup', true);

See the answer here for a little more detail http://stackoverflow.com/questions/560829/calling-base-method-using-javascript-prototype
