Hello, have you ever made some Survival map or PvP one? That requires easy - hard difficulty. So, this machine, not so complicated makes possible just pressing one button at the time, select any difficulty you want, you can even include peacefull. This machine can also select the gamemode of the player, the time (day-moon-night-midnight, which is useful if the player needs to make his respawn next to somethig, so he sets the time to night and sleep), or the area he need to teleportates. So just change the command blocks in the top to "/tp @a/p "coordinates of the area", and the bottom ones to "/say Area 1".
The jungle wood represents the INPUT, where you should put a button or pressure plate etc...
Under every Spruce wood is a non-sticky piston which will push the road of glass and oak wood in circles, almost every spruce wood...
The birch wood is where the redstone will pass, including the reapeaters.[/spoiler]
