this code basically would randomly spawn sprites(of your choice) only on the outer parameter. this code only needs; 1 variable, 1 sprite(which will be your clone)
the pen feature is simply for demonstrating you on where its been. btw all the code really does is; 1. define a quadrant 2. sends info on what values need to be what 3. then chooses an x and y value for the acorind information due to the corresponding quadrant. alot more simpler if you look inside, this is one of my more simplistic code sadly. lol XD
