Unity freezes when I'm using "while" loop

Hi, i've added this code in void Start() :

Code (CSharp):

1. int[] p = new int[256];
2.         for (int i = 0; i < 256; i++)
3.         {
4.             int val = Random.Range(0, 255);
5.  
6.             while (System.Array.Exists(p, element => element == val))
7.             {
8.                 val = Random.Range(0, 255);
9.             }
10.             p[i] = val;
11.         }

and then my unity just freezes and I have no idea what to do. Point is generate array with numbers, which are "unique"

 

Your while loop condition is never clearing: you are never changing what is inside it.

When your scripts run you have 100% of the power. If you don't return, Unity will never again run.

If you want to run this over a few frames, make a coroutine. If you REALLY must, make it a thread, but I highly recommend NOT using threading unless there is no other way. You buy yourself a LOT of headaches with threading.

Here is some timing diagram help:

If you're just looking to shuffle 256 things (my first-glance speculation about what the above code might do), then just use a Fisher Yates shuffle on a preloaded deck and it will be far more performant and reliable.

 

Okay, thank you!
