Please help about "FindWithTag" and "Array" sir.

Hello sir, I'm a newbie and here is my problem.

I try to make a group of player that enemy can detect whoever go inside their sight first, they will attack. So, I started to write a code that the enemy can detect the closest player.

Code (CSharp):

1.  
2.  public class AI_SneakingDetectZone : MonoBehaviour
3.     {
4.         public float DistanceToPlayer = 20;
5.         public float AngleToDetect = 180;
6.  
7.  
8.         public Transform[] PlayerList;
9.         public GameObject closest;
10.  
11.  
12.         void Start()
13.         {
14.             GameObject[] PlayerObject = GameObject.FindGameObjectsWithTag("Player");
15.             PlayerList = new Transform[PlayerObject.Length];
16.  
17.             for (int i = 0; i < PlayerList.Length; ++i)
18.                 PlayerList[i] = PlayerObject[i].transform;
19.         }
20.  
21.  
22.         void Update()
23.         {
24.  
25.             float DistanceValue = Vector3.Distance(transform.position, PlayerList[0].position);
26.  
27.             for (int i = 0; i < PlayerList.Length; i++)
28.             {
29.                 float CurrentDistance = Vector3.Distance(transform.position, PlayerList[i].position);
30.                 if (CurrentDistance < DistanceValue)
31.                 {
32.                     DistanceValue = CurrentDistance;
33.                     closest = PlayerList[i].gameObject;              
34.                 }
35.  
36.             }
37.             /*      
38.             {
39.                 Debug.Log("Something");
40.             }    
41.            */
42.         }
43.  
44.     }
45.  

Edit. now I got this far, it's working fine but I don't know why for some reason "element 0" is not being detected as the closest object like the other, whatever what inside of it.



For example, in this picture "H6" never gonna set place in Closest target, or whatever object that sits into "Element 0" will not work correctly.

 

Please don't assume that everyone here is male.

Code (csharp):

1.  
2.             float DistanceValue = Vector3.Distance(transform.position, PlayerList[0].position);
3.  

This sets

DistanceValue

to the distance to player 0 (but does not set

closest

).

Code (csharp):

1.  
2.             for (int i = 0; i < PlayerList.Length; i++)
3.             {
4.                 float CurrentDistance = Vector3.Distance(transform.position, PlayerList[i].position);
5.                 if (CurrentDistance < DistanceValue)
6.                 {
7.                     DistanceValue = CurrentDistance;
8.                     closest = PlayerList[i].gameObject;          
9.                 }
10.             }
11.  

...and this loop looks for player whose distance is less than that, and sets

closest

(as well as DistanceValue). So consider player 0. Is player 0's distance less than player 0's distance (which you set above, before the loop)? No, it is not. So it will never set

closest

to player 0.

The solution is to either change < to <=, or up above the loop where you first set

DistanceValue

, also set

closest

to PlayerList[0].

 

Yes, sorry I didn't think that far, I just want to be polite.

Anyway, this works !!! Thank you very much.
