Discouragement redirection cubes (help)

This is what I was talking about. If you open up the code, you'll see that the constant redirection is driven by a series of IF-statements, and I was wondering if there was a way to repeat the IF's without simply copy-pasting them beforehand, which results in a finite possibility for bouncing the laser.(try stacking the motors) maybe this could be repeated with a for-do loop?
