Cocos2D Accelerometer Z axis

Question

I am making a 2D scroller game where the player controls an airplane via the accelerometer I would like to know if it is possible to scale in and to scale out the sprite/airplane using the accelerometer z axis. I would like to know how to do this to create a depth illusion.

Any suggestion, tutorial recommendation, and comments are appreciated.

Thanks.

Answer 1

Of course, you can access the Z data from the accelerometer just like you would access the X and Y data.

Sample cocos2d projects show how to use the accelerometer; in a nutshell, you will have a method as follows in the CCLayer subclass that controls your game:

- (void)accelerometer:(UIAccelerometer*)accelerometer didAccelerate:(UIAcceleration*)acceleration
{   
    NSLog(@"Accelerometer z value is %f\n", acceleration.z);
}

Keep in mind that the accelerometer only detects acceleration - it might be a bit tricky for you to achieve exactly the desired effect. For a depth effect graphics-wise, you might want to look into parallalax scrolling.
