Can Random Function Exclude Certain Number Within Its Range?

lets say floor(Random(1,10))

Then, somehow I want to exclude number 5 and 8 from it's randomness since the beginning

If your range is that small, might as well use choose(1,2,3,4,6,7,9,10)

there's a certain situation which requires the randomness in small range. The problem is when you can't use the number that has been used. If the value has been used, the variable gets randomize again.

Now, if the available number is getting fewer, let's say only 9, it would take time before the random function hit that number.

But if I can exclude some numbers, it will solve the problem.

I see - this problem has been brought up here several times, I think I recently saw it asked again... Try this? https://www.scirra.com/tutorials/315/ge ... duplicates

I did this sample once for some else asking a similar question. Hope it helps.
