Question by You! · Jun 18, 2012 at 07:23 PM · gameobjectraycastraycasthitcomparetag

Raycast and RaycastHit failure

I have a raycast w$$anonymous$$ch is meant to check that an object with the tag "Snake" is under the cursor. I've been trying to do some research on t$$anonymous$$s problem, but none of it is making sense or it doesn't solve the problem. Here's the code:

 if(Physics.Raycast(Camera.main.ScreenPointToRay(Input.mousePosition),$$anonymous$$t,Mathf.Infinity,LayerMask.NameToLayer("Default"))){
     Debug.Log("Raycast works");
     if($$anonymous$$t.transform.gameObject.CompareTag("Snake")){
         Debug.Log("RaycastHit comparison works");
 }
 }

Neither debug log displays, the objects with the tag have rigidbodies, and I am using #pragma strict. What could be the problem?

Have you tried it without the layer mask to see if that works?

You need to use 1<<LayerMask.NameToLayer("Default") instead. I t$$anonymous$$nk LayerMask.NameToLayer("Default").value will do, too.

EDIT: Nope, the .value version works only on LayerMasks, but LayerMask.NameToLayer returns an int, not a LayerMask. Whoever wrote that API wanted to do somet$$anonymous$$ng evil.
