So, I was developing my own game with bB, and I stumbled into a problem: How to make specified random numbers? By "specified" I mean random numbers that are between two set numbers. In the game, after you defeat an enemy, it is teleported to a randomized location on the y-axis using rand command (is it actually a command or something else?). However, most of the times, the enemy teleported offscreen or into the playfield walls. Is there a way to prevent the random number from going over or below a set value?
