Hi,

I am integrating a C++ library (libbulletml) with my Cocos2D project and have run into some questions.

Question 1
So I have global variables in my C++, and the question is, they can't be accessed by the Objective C classes? (even though the Objective C ones have been renamed already to .mm) Why?

Question 2
How do I display sprites using C++? Or the nslog even?

Thanks

Answer 1:
you can access any global variable from c / objective-c / c++ as long as it is exported correctly (eg: not an static variable )

Answer 2:
You can use NSLog without problems. What's the error message that you get ?

Thanks, silly me, I forgot to rename the C++ to .mm :D And the global variables and NSLog work fine now :D
