Hi!

That's my question: I would like to build a small game, but I dont like to learn objective c, so my question is if I can use xcode and official sdk to build a game in opengl using c++. Take in account that I would like to distribute it thru appstore, so it must be legal.

Thank you for your advice.

Thread renamed and moved to the right section

Sure you can. If you use .mm instead of .m, you can use c++ syntax freely.

Hi!

Thanks for your reply.

But, why .mm and not .cpp?

where can I read more about this?

Thanks a lot.

To be honest, I'd say that if you knew OpenGL and C++ really well, the Objective-C isn't too difficult to pick up. It's just the syntax that's slightly different (like the happy use of square brackets).

I'm converting some tutorial written for windows mobile before to iPhone, you may take a look at: http://www.play3d.net/iPhone/index.html . Because lack of time, the progress will be slow. At this moment, you may find the template project for write OpenGL ES code in pure c or pure c++.

pinxue, your website is very interesting, for sure I'm going to compile something.

Just a suggestion, did you know you can modify original sdk 3 beta to create and compile 1.1.4 and opengl es??? (I prefer this rather than 1.2.0)

Edit: I downloaded some source code from your website, just a few questions:
where is makefile or how I can compile your examples?
Why are you using " glTranslatex( 0, 0, Float2Fixed(-60.0f) );" if iphone has a FPU?
Are you using offficial or unofficcial SDK in your code??? (I couldn't read anything about this)

Thanks a lot, your library seems very interesting.

It is for official SDK. You may new a coco touch project and remove all content except the info.plist and .pch, then add exist files, you also need remove reference to mainwindow.xib. I have some concern to publish the Xcode project, I will creat a makefile later, thanks for you advice.

SDK is using objc 2.0 ABI. It maybe hard to work with 1.x firmware. There are tutorial to code OpenGL ES with unofficial toolchain, please google for it, it is in standard EGL way, not eagl. (EDIT: fortunately, I wrote it down, http://www.jsfsoft.com:8080/beyond-p...007/11/16.html )

Well, it is result of iphone-dev team story. Get it from author's website: http://www.cs.cmu.edu/~ajw/public/iphone-gl/
