Hi,

Ill explain my math issue.

input.acceleration.x returns a value of -1 : 1

I have a speed rate of 4, if I multiply acceleration.x by speed at its maximum the speed is 4.

Now what I have done is clamped the returned acceleration using acceler.x = Mathf.Clamp (acceler.x, -0.3f, 0.3f);
this effectively creates a deadzone but I still want speed to equal 4 at the clamped maximum, now I’m sure its simple but I’m having a real brain ache with this.

Please help,
Thanks

If your input range is [-maxInput, maxInput] and you’d like to multiply that out to the range [-maxOutput, maxOutput], then you can multiply your input by maxOutput / maxInput.

For example, an input of 0.3, multiplied by 4 / 0.3, will become 4.
