Question by alexkaskasoli · Dec 03, 2013 at 03:28 AM · freeze

Unity unexplicably freezes on a very simple procedure

I'm working on the very beginnings of a random level generator. I'm running this code:

 using UnityEngine;
 using System.Collections;
 
 public class Generator : MonoBehaviour {
 
     public GameObject rock;
 
     // Use this for initialization
     void Start () {
 
         Desert (10, 10, 2, 2);
 
     }
     
     // Update is called once per frame
     void Update () {
     
     }
 
     void Desert(int startx, int startz, int width, int length) {
 
         Vector3 pos;
 
         for (int i = startx; i < width + startx; i++) {
             for (int j = startz; i < length + startz; j++) {
 
                 pos = new Vector3(i, 0, j);
                 Instantiate(rock, pos, Quaternion.identity);
 
             }
         }
 
     }
 }

All this does is generate a 2 x 2 square using a prefab cube of (1, 1, 1) with a texture on it.

Running this very simple code cause my Unity to freeze and pretty much die.

My computer is not a beast but it's been through much, much worse.

Can anyone explain why this would freeze?

On line 25 you have used the variable "i" in your check instead of "j". This would cause the loop to never finish as the i variable never changes in that loop.

totally missed that :D I guess that's why i never use similar letters for "for-variables". either "n", "i", "k" or if it's related to a certain axis "x", "y", "z"

Anyways +1
