Random numbers in a field

I am not sure why this code does not work

Code (csharp):

1. function RandomNumbers(){
2.  
3. var k : int = 0;
4.  
5. for (i=1; i<=4; i++){
6.  
7. randomIndex = Random.Range(0, 3);  
8. fieldRandomIndex[k] =  randomIndex;
9.  while(randomIndex in fieldRandomIndex){
10. randomIndex = Random.Range(0, 3);  
11.    
12. }
13.  
14.  
15. fieldRandomIndex[k] =  randomIndex;  
16.  
17. k++;
18.  
19. }
20.  
21. }
22.  

Thanks for any help.

 

what are you trying to do exactly?

 

I need to fill an array of X ofelements using random certain extent, but without number repetition.
I want to use this field to shuffle cards.

 

then use this:

Code (csharp):

1.  
2. function Shuffle (arr : Transform[]){    
3.     var rand : int = 0;
4.     var temp : Transform;
5.     for (var i = arr.Length - 1; i > 0; i--) {        
6.         rand = Random.Range(0,i);        
7.         tmp = arr[i];        
8.         arr[i] = arr[rand];        
9.         arr[rand] = tmp;  
10.     }
11. }
12.  

 

Thanks, very neat function.
