Raycast Distance Help

function Update () {
var fwd = transform.TransformDirection(Vector3.forward);
var hit : RaycastHit;
}
Here I have a raycast on object that will try to detect objects in front of it. If there is an object then take the distance (hit.distance) and change it into a int variable. (In Javascript)

So basically:

var dis : int = hit.distance

However for some reason it represents dis as 0.

Acording to your code, you’re not actually raycasting anything, but only declaring the variables to do so.

Try this :

    function Update () {

            var rayLength = 10;
            var hit : RaycastHit;
            var fwd = transform.TransformDirection (Vector3.forward);
		if (Physics.Raycast (transform.position, fwd, hit, rayLength)) {
                    print ("Hit Distance : " + hit.distance);
		}
	}
