Question by magarcan · Aug 19, 2013 at 01:37 PM · c#raycast

Problem with raycast

I'm trying to detect if there is somet$$anonymous$$ng between my camera and my character. Here is my code:

 void Update () 
 {
     myTarget = target.position + new Vector3(0, offsetY, 0);
     length = Vector3.Distance(transform.position, myTarget);
     
     //Shoot Raycasts
     RaycastHit[] $$anonymous$$ts;
     $$anonymous$$ts = Physics.RaycastAll(transform.position, myTarget, length);
     Debug.DrawLine(transform.position, myTarget, Color.yellow);
 
     Debug.Log("Number of $$anonymous$$ts: " + $$anonymous$$ts.Length);
 }

Where myTarget is my character (I'm using an offset to point the center of it). I'm using length for not to detect the floor.

Here is a screenshot of my scene: alt text

Ass you can see, there is somet$$anonymous$$ng in my raycast trajectory, but it's not being detected... Any idea?

Your problem is on line 8. You are using a world position for direction. Replace with:

 $$anonymous$$ts = Physics.RaycastAll(transform.position, myTarget - transform.position, length);

Make sure your objects have colliders on them. Make sure they are not in a 'no collide' layer.

Those are default boxes (with their box colliders and layer=default).
