Question by smirlianos · Oct 17, 2013 at 06:39 PM · physicsraycastdebuglinedraw

Debug.DrawLine problem

Hello,

I added a Debug.DrawLine to a script I found, and it's supposed to show me the raycast in the scene view.

However, it draws a line from the correct first position to a random one, not 10 units forward.

Any help?

 #pragma strict
 
     function Update () {
         var fwd = transform.TransformDirection (Vector3.forward);
         Debug.DrawLine (transform.position, Vector3.forward * 10, Color.red);
         if (Physics.Raycast (transform.position, fwd, 10))
         {
             print ("There is something in front of the object!");
         }
     }

I think you meant Debug.DrawRay if you want to use a direction and you want to use the fwd you calculated (though that is just transform.forward).

    Debug.DrawRay(transform.position, transform.forward * 10, Color.red);
    if(Physics.Raycast(transform.position, transform.forward, 10))
     ...
