Hi,

I am following your Tutorial 11 and try to run the project in iphone simulator 4.2 and getting following error.

AudioStreamBasicDescription: 2 ch, 44100 Hz, ‘lpcm’ (0x00000C2C) 8.24-bit little-endian signed integer, deinterleaved

After getting this error in simulator i can see only white screen.

Hope you will find some solution soon.

Thanks

Hey, I have a question. I’ve been trying to develop a game that your character or “ship” stays in the middle of the screen and the background moves behind it. Do you know how I would do this using the joy pad?

Thanks,

clayton

Hi Ali

Can you send me an example project to mike@71squared.com and I’ll take a look. Not sure off the top of my head what the problem could be without looking.

Hello Mike,
I just updated xcode to latest version and I have a little problem. The problem is that my touches (Began, Moved and ended) are not being called at all. I’m using your suggestion about not using NSTimer and create your own gameloop. and I did and in previous version of SDK it worked perfectly. but in new update nothing works. I created a sample OpenGL and and touches are called but once I use one of the the methods below the touch won’t be triggered.

#option one:

[self performSelectorOnMainThread:@selector(gameLoop) withObject:nil waitUntilDone:NO];

#option two:
[NSThread detachNewThreadSelector:@selector(gameLoop)
toTarget:self withObject:nil];

I have to remind you that inside my game loop I have the following loop as well to catch all my touches:

while(CFRunLoopRunInMode(kCFRunLoopDefaultMode, 0.002f, TRUE) == kCFRunLoopRunHandledSource);

another odd thing is that the touches will be called if I compile my program agains IPad Simulator.

I’m kind of lost, search all over net for 2 days and really need your help.

Thanks
Ali

Hi Geoff

If you edit the project settings and change the base SDK to your current SDK, the projects should all work fine.

Let me know how you get on.

An amazing bit of work you did here on this tutorial set!! I started learning C over 20 years, but gave up I learned Visual Basic instead and now I feel overwhelmed! :( Oh well. At the moment, however, these tutorials won’t run on my Macbook Pro because I don’t have xcode 2.2 and Apple doesn’t appear to want developers to have or use those older SDKs. Is there a way to upgrade these tutorials to run in SDK 3 or greater?? Thanks if you can help1 :)
