typedef FlxSpriteGroup

FlxSpriteGroup is a special FlxSprite that can be treated like a single sprite even if it's made up of several member sprites. It shares the FlxGroup API, but it doesn't inherit from it. Note that FlxSpriteContainer also exists.

When to use a group or container

FlxGroups are better for organising arbitrary groups for things like iterating or collision. FlxContainers are recommended when you are adding them to the current FlxState, or a child (or grandchild, and so on) of the state. Since FlxSpriteGroups and FlxSpriteContainers are usually meant to draw groups of sprites rather than organizing them for collision or iterating, it's recommended to always use FlxSpriteContainer instead of FlxSpriteGroup.
