How to keep endermen in an arena?
I'm making an arena minigame, and I realized a problem with the endermen: they would teleport out of the arena if left alone too long. I cannot fill in the area around the arena because the lobby is right next to it, and I really don't want to disable all the command blocks summoning the endermen. If the endermen cannot be kept in the arena, can they at least, through commands, be convinced to teleport back into the arena?
Best Answer
You have several options:
1) Move the arena to a far place, then fill out the surrounding space. To get to the arena use /tp.
2) Fill all exposed ground with slabs, water, …
3) Place a repeat and alwyas active command block with this command:
/testfor @e<kbd>[type=Enderman, x=X, y=Y, z=Z, r=ArenaWidth]
Then, place another repeat, always active command block testing if the 1st command block returned a false output. I'll use XC, YC and ZC as its coordinates:
/testforblock XC YC ZC minecraft:command_block -1 {SuccessCount:0}
Next to that command block place another one, this time chain:
/summon Enderman X Y Z
In both cases X, Y and Z above are the same coordinates.
