Random number not repeat

[char0]

Hello, I'm trying to generate random numbers not repeated for an array ".p" using the same size an array ".s$".

 

But the NPC is accusing infinite loop. How could I generate numbers not repeated 0-19 without error?

 

 

Grateful for help, Char0.

I don't understand what you wanted to do but about

How could I generate numbers not repeated 0-19 without error?

    setarray .@tmp, 0,1,2,3,4,5;
    .@size = 6;
    while( .@size ) {
        .@r = rand( .@size );// pick a number between 0-19
        set .p[.@i], .@tmp[.@r];
        deletearray .@tmp[.@r],1;
        .@size--;
        .@i++;
    }

Thank Capuche and Emistry. The Emistry code worked fine, but  both were very helpful.
