How to manage deeply z-sorting (Citrus Engine recipe)

gistfile1.as

// In your GameState class extending StarlingState (working for State and Away3DState too).

override public function initialize():void {
	super.initialize();
	
	// The group property specifies the depth sorting: objects placed in group 1 will be behind objects placed in group 2.
	// Here both objects have the same group, therefore the first added will be behind the second.
	var cs1:CitrusSprite = new CitrusSprite("cs1", {x:100, y:100, group:5, view:new Quad(100, 100, 0xFF0000)});
	add(cs1);
	
	var cs2:CitrusSprite = new CitrusSprite("cs2", {x:150, y:100, group:5, view:new Quad(100, 100, 0x00FF00)});
	add(cs2);
	
	// Each group is a container, each CitrusObject's view is added to the corresponding container.
	var container:Sprite = view.getArt(cs1).parent;

	// You can also change order into this container!
	container.swapChildren(view.getArt(cs1) as StarlingArt, view.getArt(cs2) as StarlingArt);

	// We make easily an affect to all children into the group5.
	container.filter = new BlurFilter();

	// group's container are automatically created when a new group is precised into an object.
	// In our case group from 0-5 are created, default object group is 0.
