Question Unity crashes when I place my tiles.

My code is this:

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4. using UnityEngine.Tilemaps;
5. public class MakeTiles : MonoBehaviour
6. {
7.     public Tilemap map;
8.    
9.     public Tile[] avTiles = new Tile[16];
10.  
11.     private Vector3Int pos;
12.     void Start()
13.     {
14.         for (int y=0;y < map.size.y; y++)
15.         {
16.             for (int x=0;x < map.size.x; x++)
17.             {
18.                 pos = new Vector3Int(x, y, 1);
19.                 map.SetTile(pos, avTiles[0]);
20.             }
21.         }
22.     }
23.  
24.    
25.     void Update()
26.     {
27.        
28.     }
29. }
30.  

Now I don't understand what I am supposed to fill avTiles with I have been using my spritesheet files.

I really don't need any type of behavior for these.

 

Don't do it in Start() and/or don't use map.size for loop parameters. As you add tiles this value increases so you may be adding tiles for an infinite amount of time.

use coroutine to place tiles slowly, doing it all on the same frame is too heavy
