/**
|
|
* A Group is a container for display objects that allows for fast pooling and object recycling.
|
|
* Groups can be nested within other Groups and have their own local transforms.
|
|
*
|
|
* @class Phaser.Group
|
|
* @extends PIXI.DisplayObjectContainer
|
|
* @constructor
|
|
* @param {Phaser.Game} game - A reference to the currently running game.
|
|
* @param {Phaser.Group|Phaser.Sprite|null} parent - The parent Group, DisplayObject or DisplayObjectContainer that this Group will be added to. If `undefined` it will use game.world. If null it won't be added to anything.
|
|
* @param {string} [name=group] - A name for this Group. Not used internally but useful for debugging.
|
|
* @param {boolean} [addToStage=false] - If set to true this Group will be added directly to the Game.Stage instead of Game.World.
