I'm attempting to fill a column of 4 squares with color. Once all 4 are filled, I move on to the next column.

I'm picking random values from an array by using

array.at(round(random(0,3)))[/code:31vn5vtc] to pick which square to fill but the problem is it will repeat values and I don't want it to do that. I want it to only pick 4 times and then move on.

Should I delete them as I pick them?

That's what I would do: if I wanted to keep the array of random numbers, I'd copy the array first, and then pick-and-pop the array as I go along.
