iOS Accelerometer :S

[JavaWizKid]

I've coded this:

- (void)accelerometer:(UIAccelerometer *)acel didAccelerate:(UIAcceleration *)aceler {
	
	if (fabsf(aceler.x) > 0.5)
	{
		spaceshipVelocity = CGPointMake(kSpaceshipMovingrX,kSpaceshipY);
	}
	if (fabsf(aceler.x) <= 0.5 && fabsf(aceler.x) >= 0)
	{
		spaceshipVelocity = CGPointMake(kSpaceshipX,kSpaceshipY);
	}
	if (fabsf(aceler.x) < -0.5)
	{
		spaceshipVelocity = CGPointMake(kSpaceshipMovinglX,kSpaceshipY);
	}
	if (fabsf(aceler.x) >= -0.5 && fabsf(aceler.x) <= 0)
	{
		spaceshipVelocity = CGPointMake(kSpaceshipX,kSpaceshipY);
	}
}

and for some reason it doesn't execute the negative commands? Any suggestions as to what is wrong?

fabsf() returns an absolute value. Thus, there are no negatives.

Any workaround?

Workaround? I'm not sure you're approaching this correctly if you think a workaround is the solution. Maybe do a bit more research into UIAcceleration, UIAccelerationValue and how those work.

I meant a way to get negative values because tilting one way and only one way seems a bit pointless

UIAccelerationValue can already contain a negative.
