// Inside a class which extends CitrusObject e.g. CitrusSprite, APhysicsObjects...
kill = true;

// If you have an access to the variable of the object :
hero.kill = true;

// Or within a State class (the previous code works too) :
remove(hero);

// Citrus object's view management is powerful: when a view is added to the object it is loaded and added to a template 
// called SpriteArt which is a container of your art. This template allows to load external files thanks to their path.
// It works the same way with Starling.

var _hero:Hero = new Hero("my hero", {view:"myHero.swf"});
// _hero.view refers to the path "myHero.swf" not to the swf loaded.
// If the view specified is a DisplayObject, you can directly make whatever you want on it (filter, blendMode, ect).

var _heroGraphic:SpriteArt = view.getArt(_hero) as SpriteArt;
// _heroGraphic is the container of the art. It will loads and display the art. Most often you will work with this.
