Hi Ray,

Thanks for the great insight of the tutorial. I am an acquaintance of gaming and using high graphics in iPhone.

Would like to know, how the gameKit from iphone sdk can be related to Cocoas2d or any other gaming framework(box2d, chipmans…. etc),

In case anyone comes across this warning, as of cocos2d v 0.99.5 CCColorLayer has now been deprecated. You will need to use CCLayerColor instead.

Ray:
Great tutorial. I was trying to add some additional sound effects when something was hit and put it in the update method the following:
[[SimpleAudioEngine sharedEngine] playEffect:@”shooter_hit.caf”];
The audio file has the following info:

File: shooter_hit.caf
File type ID: caff
Data format: 1 ch, 44100 Hz, ‘lpcm’ (0x0000000C) 16-bit little-endian signed integer
no channel layout.
estimated duration: 1.390 sec
audio bytes: 122600
audio packets: 61300
audio 61300 valid frames + 0 priming + 0 remainder = 61300
bit rate: 705600 bits per second
packet size upper bound: 2
audio data file offset: 4096
optimized
sound check:
approximate duration in seconds 1.39
—-

When it plays it sounds all garbled coming out of the simulator. Is it the sound is too long for a collision hit or could it be something else? I am using 0.99.4.

Are you thinking about teaching your class again!

Thanks,
Tony

Sorry what I meant is in a game where the player has various abilities.

Each ability is in the form of a different type of gun so selecting an ability should change the projectile that is fired.

So i am looking to create a method that lets you do just that.

@pppoe, @Stimpy: Thanks! :]

@Numpol: Glad you got it working!

Just in case someone else reading this has the same question, here’s the answer. In the latest version of Cocos2D, switch to RootViewController.m, and inside the case for GAME_ROTATION == kGameAutorotationUIViewController, switch the line to say the following:

return ( UIInterfaceOrientationIsPortrait( interfaceOrientation ) );

For more information, here’s a good guide on autorotation in the 0.99.5 templates:
