Yes, zones don’t shrink and can’t move on their own… (sadly) I tried making this in my game (moving zones) but, it used up so much memory and, well, took like 200 zones. I’m not saying its not possible though! I’m just saying that it takes time and is memory consuming…
This would be made using a bunch of zones that activate on a timer/clock so maybe check out the guides that @THEHACKER120 posted
