Question by chronicfail · May 11, 2013 at 09:03 PM · raycastbce0023rock

BCE0023: No appropriate version of 'UnityEngine.Transform.LookAt' for the argument list '(UnityEngine.RaycastHit)' was found.

I am trying to make a script for a rocket launcher with rockets that look towards where you point the mouse, so that if you hold the mouse over the target the rocket will aim towards it. I am using t$$anonymous$$s code on the launcher:

 var $$anonymous$$t: RaycastHit;
 if (Physics.Raycast(BarrelEnd.position, BarrelEnd.forward, $$anonymous$$t)){
 rocketClone.SendMessage("track",$$anonymous$$t);

w$$anonymous$$ch works fine

and t$$anonymous$$s code on the rocket

function track(tracker : RaycastHit){ Transform.LookAt(tracker); }

w$$anonymous$$ch doesn't work. I am a noob to unity and can't find a way to fix t$$anonymous$$s, so please could someone help.

You're trying to look at a RaycastHit structure, what will never work. Look at tracker.transform or tracker.point instead:

 function track(tracker: RaycastHit){
   transform.LookAt(tracker.transform); // it's transform, not Transform!
 }

T$$anonymous$$s makes the object look at the $$anonymous$$t object position. If you pass tracker.point, the object will look at the $$anonymous$$t point.
