   I'm trying to copy a CCSprite that's been subclassed. Let's say the file is called Names. And the original variable name is bob. If you wanted to copy all the actions of bob, how would you do that? I've been looking at this thread. How do you do as @jd said, and add the action as a property? I'd need to be able to copy "bob" many times.

   Thanks!

   And by copy bob, I mean duplicate it.

   I would write a Bob class that inherits from CCSprite. You would then be able to include all the actions you want to many instances of Bob.

   @hm50 If I understand you correctly, you mean making a new class that's inside the Names file, maybe calling it bobCopy. Then how would I make it that bobCopy is bob, but a copy of it?

   What @hm50 means, and s/he is correct, is that you should create a class called Bob that inherits from CCSprite, so:
   @interface Bob : CCSprite

   Then depending on when you want the actions to run, in a method of Bob, for example lets say you have an animate method, then in that method you might have:

   - (void) animate {
        [self runAction:[CCRotateBy actionWithDuration:5 angle:360]];
   }

   Then just call the animate method on the Bob instances, and the sprite will run all of the actions in the animate method, effectively synchronizing it with other sprites when you call animate on them at the same time.

   Not the best explanation ever, but yeah. :D

   Thanks @liquidfire, but I was asking how to duplicate the sprite "bob". ie - If you wanted to make enemy characters, how do you duplicate them?

   Maybe you should listen to the advice that has been given to you many times and learn the basics first.

   Instances are one of the most basic concepts in Objective-C. You should really stop resisting and just learn it.

   @Benihana I know how to make an instance variable obviously. I just don't know how to incorporate the same actions, methods, etc. into that second variable.

   At this point it's not obvious, and an instance variable is not the same thing as an instance. It would be one thing if you were having issues using the same actions in multiple instances of a class (actions must be copied, everyone tries to use the same ones), but you don't even seem to know how to allocate and initialize a new instance.

   This is not cocos2d related, and one of the very first things you learn when learning Objective C.
