generate a random number every xx seconds with no repeat.

Hello,

I've searched the web for this (and there's lots on scirra) but I just can't seem to get it working.

what I'm trying to do is:

generate a random number every xx seconds with no repeat.

"Textbox = random number

System Every 3.0 seconds > change the Random number (but no repeats)."

That's it> should be simple (I think I'm simple too)... I've tried Array count but it's not behaving as described.

Can anyone please assist.

Read a bit in the forum recently about the use (or rather uselessness) of the WHILE event ....

Excellent for this purpose:

That's a really nice example especially because you don't need to resort to arrays. One adjustment I'd make however is to:

int(random(FirstNumber,LastNumber))

I'd change this to:

floor(random(FirstNumber,LastNumber+1))

Otherwise the first and last number will be picked half as often as every other number.

Otherwise the first and last number will be picked half as often as every other number.

The concept of this is that it eventually every number in the range will get picked (even if its just at the end ^_^)

Yes, I totally get that, but if you want to ensure that the order of picking is truly random then using int will more often push the first and last number to the back of the sequence; using floor should eliminate that bias.

Very true !!

Floor combined with the +1 would indeed make it more accurate (or rather random hehe)

Can i add that there is an awesome plugin for that ?
