Vehicle wont turn

I am creating a hover racer game and we have almost everything working but there is one major problem, the player cant turn left and right. I know the problem has something to do with the script that aligns the player to the angle of the track but I don't know what part is causing it. Here is the script

Code (JavaScript):

1. var smooth = 10;
2.  
3. function FixedUpdate()
4. {
5. //make platform adjust terrain rotation
6. var rcHit : RaycastHit;
7. //Make raycast direction down
8. var theRay : Vector3 = transform.TransformDirection(Vector3.down);
9. if (Physics.Raycast(transform.position, theRay, rcHit))
10. {
11.      //this is for getting distance from object to the ground
12.      var GroundDis = rcHit.distance;
13.      //get rotation
14.      targetRotation = Quaternion.FromToRotation(Vector3.up, rcHit.normal);
15.    
16.      //Smooth rotation
17.      transform.rotation = Quaternion.Lerp(transform.rotation, targetRotation, Time.deltaTime * smooth);
18. }
19. }

 

there's no player input in that script... ?

It's a fixedupdate so there shouldn't be really... but how is the player input handled?

 

Player input is in another script, turning is done with AddTorque. All the other movement is done with AddForce.

 

If turning is done with AddTorque, then you shouldn't be messing with the transform.rotation

 

The transform.rotation is to align it to the track, anything else doesn't work well

 

if you update the rotation you are overriding the updates done by the physics engine with the torque...

 

so how would i fix this

 

You need to use a torque to align it to the track as well
