Need help with camera offset

Unity Engine
1 
var allowedLayer :LayerMask = -1;
var offsetFromTerrain : float;

function Update () {
		var hit : RaycastHit;
		if (Physics.Raycast (transform.position, -Vector3.up, hit, 100.0,allowedLayer)) 
		{
			transform.position.y = hit.point.y + offsetFromTerrain;
		}
	}

And here is the result
Watch it. And you’ll know what my problem is

If all you want is the ability to place the camera a certain amount above the terrain, why not use a collider of some sort?

You could just place the camera as the child of a cylinder and give the cylinder constraints for rotating on the x and z axis. Then move the camera up by your offset from the terrain variable. Anytime you want to move the camera give it a push through a rigidbody connected to the cylinder.

if you’re trying to orient the object to “walk” on the terrain, just cast a ray downwards, get the normal of the surface from the hitInfo, and rotate your object so its up vector points in the same direction as the normal
