Stick to ground script

Hi there!

I'm trying to make a space race idea and I need the vessel to stick to the track while moving. Is there a s script that can do this???

 

You can always raycast downwards and set its position to wherever the hit.point is. Getting the rotation right will be a little tougher, but using hit.normal and such can be used to solve that.

 

I am using the script below and the vessel keeps on jumping all over the place!

Code (JavaScript):

1. function Update () {
2.     var hit : RaycastHit;
3.     if (Physics.Raycast (transform.position, -Vector3.up, hit)) {
4.         var distanceToGround = hit.distance;
5.         //use below code if your pivot point is in the middle
6.         //transform.position.y = hit.distance - transform.GetComponent.<Collider>().bounds.extents;
7.         //use below code if your pivot point is at the bottom
8.         transform.position.y = hit.distance;
9.     }
10. }

 

You should probably use the vessel's down and not the global down?

 

I change up to down and it seems to work better but still it has problems...
