Question

Just wondering how I can get the position of a node that will be the current position if it is not moving, but if there is a CCMoveTo action being performed I need the position it is moving to.

Is this already built in or will I have to implement it myself, if so any suggestions on how I would go about it?

Thanks for the help,
Ben

Usually, if there are already built-in methods that “single-lined-ly” give you the information that you want, for example using [[CCDirector sharedDirector] running Scene] to get the current scene, it is a bad idea to create an ivar to keep track of the information for later querying.

But if using the built-in methods are hackish or long-winded, with no guarantee for accuracy, then it is better to create an ivar.

So, just create an ivar on that node that you update whenever the position is changed or a CCMoveTo action is assigned.

Note: I’m calling the -(NSArray *)getActionsByTarget:(id)target method as hackish because it is not guaranteed that you can find the CCMoveTo action in it. The action might be embedded deep in [CCSequence actions:[CCFadeIn ...], [CCSpawn actions:[CCCallBlock actionWithBlock: ^{ [self runAction:[CCSequence actions:[CCDelay ...], [CCMoveTo ...], nil]]; }], [CCMoveTo ...], nil], [CCMoveTo ...], nil]. Now how in the world you would implement the logic that can correctly find all the three CCMoveTo and deduce which of it will give the final position?
