I'm planning on learning 3d game development for the iphone using a 3d engine, but because of lack of tutorials for the iphone I was planning on using C++ game tutorials and making the necessary changes.
The problem is that I've had limited success when searching for things such as 'c++ 3d fps tutorial ' I dont really get anything useful.
Are there any 3d c++ tutorials you can recommend?
There are no tutorials on writing a MS Word killer either.
That's because tutorials are for explaining specifics. There are tutorials for "how to implement bump-mapping in your game", but not for "how to make a complete AAA game from scratch".
If you feel you need a tutorial for that kind of thing, you're not ready to make it.
All programming is about splitting up complex tasks into tiny simple ones. You need to do the same.
Instead of wondering "how do I write a FPS game on iPhone", you need to ask:
...
and so on. There are a million steps on the way that can be solved individually. And at the end of the road, you'll have your game.
But there is no tutorial in how to make a FPS game on iPhone for the same reason that there are no tutorials in "how to make a fighter jet" or "how to achieve world peace". People who need to tutorials for it won't be able to do it, and a tutorial would be so big and complex, it'd be pointless.
You'll have to learn the hard way: by picking up a book on 3D graphics, learning how to program the iPhone, learning how to use OpenGL, learning how to do everything along the way. By looking up resources explaining that speciifc problem, rather than simply reading the next paragraph of your uber-tutorial.
Okay, after the short comment, a little bit more description. First of all you most know there is no such thing as simply generic 'game programming', programming a game consists of many different topics. For example, 3D rendering, audio playing, gameplay coding (including AI), possibly network coding, some advanced I/O libraries, ... .
The reason for this is most games have different needs, for example most of the above will be very different for RTS vs FPS games. Even more specific examples, Doom³ had totally different needs than half-life² or far-cry (old examples but it's been a time since I really played games myself :p). The first one needed advanced lighting, shadows, awesome interiors, the latter ones needed impressive outdoor scenarios.
While you may think 'yeah, but these are all great professional games, I'm trying something simple', it is quite essential to understand this even applies on your level. There is no magic tutorial that will learn you how to write FPS games.
As I said in my comment, a good place to get started is Gamedev.net, they really have a huge collection of tutorials, articles and a good support forum. Here you can learn from which components a game is typically build, how you can learn these components (and which you need for the kind of game you want to write), ... .
Good luck and have fun with it, game developing is a really fun thing imho, but it's a long path to master it even a little bit :).
