Question

I think I might be causing a bug in my code because I’m unclear about what the cleanup: part of removeChild:cleanup: method of cocos2d ccnode class.

Thanks.

Answer 1

It stops all actions and unschedules any scheduled selectors associated with the CCNode, basically removing any references that cocos could have to the object. It also propagates the cleanup invocation to all of the object’s children. If the object is an autorealease-able object and you did not retain a reference to it, the memory should be reclaimed by the objective-c runtime, for the object itself and its children. That would be true of almost all objects, but not if you added the objected as a targeted touch delegate. In that case, I would recommend to override the onExit method as this:

- (void) onExit{
    [[CCTouchDispatcher sharedDispatcher] removeDelegate:self];
    [super onExit];
}

this way, the object will be fully release-able when you cleanup.
