Arrows on HUD and Distance to Target HELP!

I found this little gem in the Unity docs.

Code (csharp):

1. / Print the name of the closest enemy
2. print(FindClosestEnemy().name);
3.  
4. // Find the name of the closest enemy
5. function FindClosestEnemy () : GameObject {
6.     // Find all game objects with tag Enemy
7.     var gos : GameObject[];
8.     gos = GameObject.FindGameObjectsWithTag("Enemy");
9.     var closest : GameObject;
10.     var distance = Mathf.Infinity;
11.     var position = transform.position;
12.     // Iterate through them and find the closest one
13.     for (var go : GameObject in gos)  {
14.         var diff = (go.transform.position - position);
15.         var curDistance = diff.sqrMagnitude;
16.         if (curDistance < distance) {
17.             closest = go;
18.             distance = curDistance;
19.         }
20.     }
21.     return closest;    
22. }

How do I display a distance counter to target. I have the target tagged as "Goal" and I want to show how far I am away in distance from the goal and as I move towards it or away the counter goes down or up. Also, how do I show arrows on the HUD to tell where enemies are. Enemies are tagged "Enemy". Thank you Just need some help or point me in the right direction.

 

Well to show the distance between you and the closest enemy do

function UpdateCounter ()
{
Array enemies = gameObject.FindGameObjectsWithTag("Enemy")
Transform closest;
float bestScore;
foreach(Transform e in enemies)
if(Vector3.Distance(transform.position,e.position) < bestScore)
closest = e;

//This you set yourself (Create other -> GUI Text) then just make it a variable
GUITEXT.text = "Distance to enemy: "+Vector3.Distance(transform.position,closest.position)
}

Sorry I don't know how to do scripts in the forums. This should help though. You may not want to call this every frame because they way I wrote it is pretty slow, but if you update it like every 4-10 frames it should be fine. The HUD telling you where enemies are requires a minimap, I've never done one so I don't have the code memerized, but ask around or just try it yourself. Hope this helps

 

@Cat_ninja - Thanks a bunch. I will give this a shot.
