How do i fix this infinite loop?

I am new in C# and Unity, I would love an explanation of the issue but simple fix would be just fine. Thank you.

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5. public class moveT : MonoBehaviour {
6.  
7.     public GameObject treeFab;                                 //The tree game object.
8.     public int treePoolSize;                           //How many trees to keep on standby.
9.                                                               //How quickly trees spawn.
10.    
11.     private GameObject[] trees;                                   //Collection of pooled trees.
12.                                                                
13.     private Vector3[] pos1rot1;                        //Collection of pooled Positions.
14.  
15.    
16.  
17.    
18.     void Start ()
19.     {
20.        
21.         trees = new GameObject[treePoolSize];
22.         pos1rot1 = new Vector3[5] ;
23.         int i;
24.         for (i = 0; i < 5; i++)
25.        
26.             pos1rot1[i] = new Vector3 (-123+10*i, 27-i, 74+3*i);
27.  
28.        
29.        
30.         for ( i = 0; i < treePoolSize; i++)
31.         {
32.            
33.             trees[i] = (GameObject)Instantiate(treeFab, pos1rot1[i % 5], Quaternion.identity);
34.  
35.         }
36.            
37.                      
38.            
39.        
40.     }
41.    
42.     private int index = 0;
43.    
44.     void Update ()
45.     {
46.         if (gameControl.instance.gameState == 1 && (trees[index].transform.position.z < -13f))
47.         {
48.            
49.             trees[index].transform.position = pos1rot1[Random.Range(0,5)];
50.             index++;
51.         }
52.         if (index >= treePoolSize)
53.             index = 0;
54.  
55.     }
56. }

 

I don't see any code there that could cause an infinite loop. I see some weird concepts going on (why are you setting the position in Update's, after they are spawned?), but no infinite loop potential. It's possible that Start() could take a long time if your treePoolSize is really big, but not to the point of freezing Unity.

I can think of 2 possibilities:
1) It's another script entirely that's causing the infinite loop.
2) This script is on the prefab that's being instantiated. So this script generates a tree, which has this script, which generates a tree, which has this script, which.....

 

2) This script is on the prefab that's being instantiated. So this script generates a tree, which has this script, which generates a tree, which has this script, which.....

That was the problem, thanks a lot man

 

This will eat whole performance. Forget this way.

 

The guy just trying to learn the very basics, he can worry about that much.. much later.
