How do I make a rabbit spawn every x amount of seconds?
P2, is it possible to make an armor stand wave at someone when they walk through a door ?, if so How do I do that aswell ?
The first can be accomplished using repeaters and a command block to summon the rabbit, you can use the internet to calculate how many repeaters = how many seconds
As for the second, Java Edition is just way better for this sort of stuff.
