Question by Smull · Apr 25, 2014 at 02:17 AM · javascriptraycast

Have to press Fire1 button twice to run if statement?

I'm trying to make something happen when my raycast hits a specific object at close range, the problem I'm having is that when I do, I have to press the "fire1" button twice before anything happens. The script is attached to the built in first person controller asset.

 var hit3 : RaycastHit;
 var Distance3 :float;
 
 function Update () {
 
 Distance3 = hit3.distance;    
         
         if (Input.GetButtonUp("Fire1") && Physics.Raycast (transform.position, transform.TransformDirection(Vector3.forward), hit3) && hit3.collider.name == "BED>ELEC" && Distance3 < 3)
         {
             Debug.Log("SUCESS");    
         }
 }

I'm very new to scripting and Unity in general, so I might be missing something obvious. Any help is greatly appreciated! :)

You have your Distance3 set/check as part of the if(Input....) bit which is probably null until the first click (which sets hit3 to something)

I'm not sure I understand. If Distance3 is part of the if(input...) it doesn't have to be within the { } tags? Because as I see it now Distance3 is set outside of the if(input...)?

Edit: Never$$anonymous$$d, I think I understand now, thanks!

You are setting Distance3 to hit3.distance, but hit3.distance is not computed until the firstRaycast

Yarp. So Distance3 is always equal to the distance calculated during the previous frame.

Ins$$anonymous$$d of assigning it to a local variable just use hit3.distance
