#summary Frequently Asked Questions

Can I use cocos2d for iPhone in my closed-source iPhone application ?

Yes, you can.

cocos2d for iPhone is licensed under the 'cocos2d for iPhone license'. Basically it is like a LGPL license but allows you to use the library as a static library or by including the cocos2d for iPhone sources in your project.

Remember that cocos2d for iPhone follows the copyleft idea. So if you improve the library, send me the patches or make them public so that I can include them in future releases.

If you have any doubt, please read the 'cocos2d for iPhone license': http://cocos2d-iphone.googlecode.com/svn/trunk/LICENSE

Can I use 3D objects in cocos2d ?

You can include some 3D objects in your 2d game to improve the quality of your graphics without any problem.

Also, the default projection matrix of cocos2d is a 3D one, so probably you won't need to change it.

I've found a bug / I have an enhancement proposal. What should I do ?

Please, open a ticket in the issue tracker: http://code.google.com/p/cocos2d-iphone/issues/list .
