Non-repeating Random Numbers

Random numbers without repeating

[j2trumpet]

I've got my random number generator created and functioning, but I need it to not repeat any numbers as it runs. How do I do that? Thanks for the help.

If you control the output, then - by definition - your generator will be non-random

Thanks for the advice, but that doesn't answer my question.

Can anyone else help me?

Store the 'used' answers. If you get a used answer try again.

How do I do that?

var used = [];
...
function getUniq(){
var n;
while ( used[ n = getRand() ] ){}
used[ n ] = true;
return n;
}

replace getRand() with your get random code

Another way would be to splice/remove the element from the random array until it's length is zero. When it reaches zero length, repopulate it.
