I have recently created an Asteroids game/app for one of my CS classes with openGL, GLU and C++ for Linux. The teacher told me that if I get it to run on the iPhone he would give me extra credit. I have been looking around and I think I have to develop/port it to Objective C using the iPhone Development Kit. My questions are:
I have not tried anything yet, because I would like to know first what you guys think. You do not have to tell me exactly what to do, but I would highly appreciate if you would point me in the right direction.
Thanks.
Well, if you don't want to port your program into another language. You CAN use SDL2, it seems pretty stable and it works on iOS (iPhone/iPad/iPod Touch). All you would have to do is change your code and then play around with the controls. You'll have to clone the Mercurial repo from http://hg.libsdl.org/. It will come with a README.iOS file, in which describes how the port works and some other details. I am not sure if it has multi-touch support yet, I have not tested it.
Also, you can use immediate mode on the iPhone, you just can't use OpenGL ES 2 if you do that. All you have to do is make a context for OpenGL ES 1.1.
And you WILL need a Mac, or perhaps you could get a Hackintosh to compile your code and then run it with a jailbroken iPod/iPhone/iPad.
NOTE: I believe I have heard of some people compiling their code on a Hackintosh and then submitting it to the app store from a Mac within an Apple store.
