Basic Group

FlxGroup is a way to separate, and layer FlxObjects. This can be useful to ‘force’ your objects’ draw-order, or to help with overlap/collision detection, etc. You can optionally limit the number of objects a group can hold.

// create a FlxGroup called group, limiting it to 50 objects
var group = new FlxGroup(50);

// add sprite to group
group.add(sprite);
