I'm making a game where you create springs and I want them to be fully removed when they go off stage. The only way I know how to go about this is "removeChild(thing);" but that just hides it. Is there a way that can actually delete the instance because I'm not sure how. It also displays this error which I don't fuly understand.

ArgumentError: Error #2025: The supplied DisplayObject must be a child of the caller.
at flash.display::DisplayObjectContainer/removeChild()
at MethodInfo-49()

Hi.

Also remember that besides removing from the display list, you must remove all event listeners from the object and set it to null.

In this way you can avoid null references in the event handlers and you make sure that it can be effectively garbage collected.
