   Sorry for the very generic title since I have very generic questions about game programming with Cocos2d..

   Is it a safe bet to say that all the games that I see being developed here is done almost purely within Cocos2d (and Box2d, Chipmunk or homegrown physics)?? How much of what happens also relies on stock OpenGL as well?

   I'm a complete newb when it comes to iPhone development and have been playing with Cocos2d for a little while to get comfortable with that and Obj-C and looking at the quality of games that are being released with Cocos2d, I just wanted to know how much of that is Cocos2d or if it was entirely cocos2d..

   Regards

   Shape Reactor was built entirely using the cocos2d game engine. Shameless plug :D

   @jonathan0382, that's great to know..so I actually have some hope of doing something productive once I really get good at cocos2d..and all is not lost..:)

   So far the only thing I've had to rely on OpenGL for is drawing shape primitives. We've developed both Hot Dog Down a Hallway and Shave Me! using Cocos2d and are currently working on our third title.

   Objective C is straightforward particularly from a solid C background and xCode is a solid development environment.

   One thing I don't recommend is to switch rapidly between ObjC, Java, and AS3 from day to day as I have been doing recently- it becomes quite hard to keep everything straight! :)

   We modified some code inside cocos2d and made our extensions (some are in issues waiting to be added to cocos2d trunk). I use a lot of OpenGL in my code and implement my own draw. One example is using FBO to create effects at runtime. This can't be easily done with cocos2d (although for most project you don't need it either), so you need to use OpenGL inside a class inheriting CocosNode. We also made some actions (like a label animator where you specify a delay and an array of string and it sets the label to the strings).

   It really depends on the size and the needs of your project. When we release (cross fingers for before 2010), I think we might be the largest cocos2d project yet (shameless bragging, but we have 15k lines of code to date against 16300 for cocos2d [without contribs]) :P

   edit: btw, cocos2d is really clean when it comes to OpenGL states, although sometimes there are problems (ColorLayer right after Sprite, for example, doesn't clean the texture and shows the ColorLayer incorrectly). Once you know the quirks (having the code helps a lot), you can mix your own OpenGL easily.

   Thank you very much for the information..this bolsters my confidence that I might be able to produce something in actuality to resemble what's in my head. :)

   @jonathan0382: I can't talk about it yet (under NDA), but we'll have a couple video inside of 1-2 months. You guys will know for sure.

   @Poltras: cool, I look forward to it. 15k+ lines of code sounds epic :D
