Finding the closest obstacle to you when you are an obstacle.

Question

Hi. I'm trying to think of a way to find all obstacles in my game that use the obstacle tag. The confusing part is that my player is an obstacle to other players, but there is no point in counting yourself as an obstacle, so I need to exclude myself in this script. Have any idea how? All I need to know is the closest obstacle to me other than myself.

 function FindThatObstacle():GameObject{
 
     var gos:GameObject[];
     gos=GameObject.FindGameObjectsWithTag("Obstacle"); 
     var closest:GameObject; 
     var distance=Mathf.Infinity; 
     var position=transform.position; 
     // Iterate through them and find the closest one
     for (var go : GameObject in gos)  { 
         var diff=(go.transform.position - position);
         var curDistance=diff.sqrMagnitude; 
         if (curDistance<distance) { 
             closest=go;
             distance=curDistance; 
         } 
     } 
     return closest;    
 }

 // [...]
 var position=transform.position; 
 // Iterate through them and find the closest one
 for (var go : GameObject in gos)  {
     if (go.transform != transform) {
         var diff=(go.transform.position - position);
         var curDistance=diff.sqrMagnitude; 
         if (curDistance<distance) { 
             closest=go;
             distance=curDistance;
         }
     }
 }

This should do the trick ;) I'm not sure if UnityScript knows continue but it's a quite basic keyword so it should work. I'm a C# user ;)

Hmm... it still seems to return the closest gameobject which is it's self.

Should I try break; ins$$anonymous$$d of continue;?

That doesn't make sense ;) Are you sure UnityScript compiles the script? No errors? You could also invert the condition and surround all the code with it. I'll change the example...

Have you tried printing the name of the closest object? Also make sure any child objects of your player arn't tagged "Obstacle". They would be found as well.

You could also check like this

 if (go.transform.IsChildOf(transform))
     continue;

IsChildOf checks if the object is a child, deep child or the transform itself just to be on the sure side ;)
