Question by tomazsaraiva · May 06, 2011 at 03:41 PM · car

Steering Wheel Problem

Hey

I have this code to making a steering wheel:

var rotationSpeed : float = 100.0;

function Update () {

     var rotation : float = Input.GetAxis("Horizontal") * -rotationSpeed * Time.deltaTime;   

     transform.Rotate(0, 0, rotation);

}

It is working ok but I need the steer to comeback to the original position when I stop pressing the arrow keys. How can I do that?

I tried using Quaternion.Slerp but I can't define the original position to comeback to.

Thanks for any help

Create a quaternion variable to store the default rotation in local space on awake or start, then you can lerp/slerp just fine from transform.localRotation to that variable.

Yeah you are right, I was using transform.rotation ins$$anonymous$$d of the localRotation, that was the error. Thanks

My problem is solved thanks to Alec Slayden, here is the code:

var rotationSpeed : float = 100.0; static var origRotation : Quaternion;

 function Awake () {

     origRotation = transform.localRotation;
 }

 function Update () {

         var rotation : float = Input.GetAxis("Horizontal") * rotationSpeed * Time.deltaTime;   

         transform.Rotate(0, rotation, 0);

         transform.localRotation = Quaternion.Slerp(transform.localRotation, origRotation, Time.deltaTime);
 }
