Question by iDesign · Jul 23, 2014 at 09:45 PM · rayboxcollider

If Box Collider has been hit

So I did some research and found that I needed to create a ray in order to see if a Box Collider has been hit.

In my game I have a cube (controlling the main camera) and a sphere (with a Box Collider). When my cube touches the sphere I want "Hit" to be displayed in the Console so...

 Debug.Log("Hit");

However, I'm not exactly sure that I fully understand the ray/collider code, here is what I did so far:

 #pragma strict
 var Player: GameObject;
 
 function Update(){
         var ray : Ray = Player.ScreenPointToRay(Input.mousePosition);
         var hit : RaycastHit;
         
         if (collider.Raycast(ray, hit, 100.0)) {
             Debug.Log("Hit");
         }
     }

Hope I can get some useful input, thanks,

Instead of raycasting use

 OnCollisionEnter(col : Collision){
     if(col.gameObject.tag == "TagToCollideWith")
         DoSomeLogicHere();
 }


You can read about Unitys builtin methods and when are they executed here: http://docs.unity3d.com/Manual/ExecutionOrder.html

I tried:

 #pragma strict
 
     function OnCollisionEnter (col : Collision)
     {
         if(col.gameObject.name == "Troll") // tag doesn't work either
         {
             Destroy(col.gameObject); 
         }
     }

But that didn't seem to work.. Any ideas?

Edit: Tried everything including codes from tutorials but I couldn't get anything to work. I'm starting to think that it might be a problem with the settings/componenets of my objects. Could you help me out?

Edit: User a trigger ins$$anonymous$$d an it worked.

OnCollisionEnter(col : Collision) works with colliders OnTriggerEnter(col : Collider) works with triggers,

You need to attach collider component and adjust its settings to your needs :)
