I'm making a Boss Arena with command blocks and no plugins, I got the bosses and spawn and tps to arenas done. But the problem is, that I don't know the command to teleport players when they die.
(Note: Umm, uh, someone edit this please)
You simply use
/tp @p ~n ~n ~n. The first ~ teleports the player a certain amount of blocks long, and in a plus shape with the third ~. the second ~ teleports the player up. If you want the player to be teleported downwards or the other direction, use negatives (-). n is the number of blocks they will be teleported. If you just want to teleport a player to a single location, press (Fn +)F3 where you want the player to teleport. Then, look at XYZ (start of second part). Remember the numbers there, or if needed, type the numbers in the chat. If I wanted a player to teleport to the coordinates 184, 68, 264 then I would type:
/tp @p 184 68 264 WITHOUT the ~'s. However, if I typed
/tp @p ~184 ~68 ~264 then I would then I would teleport the closest player to the blocks 184 right, 68 up and 264 forwards. Or 184 forwards, 68 up and 264 right. @p teleports the closest player, @a teleports all players and @r teleports a random player. If for some reason, as if you want to teleport the boss in use something like
/tp @e[type=wither]. As for your question, set the spawn point at the very center of the world. Get the coordinates to the arena spawn point. Fill the spawn chunk with quartz. Place string everywhere on the quartz then
tripwire on the... well, here's a example:
q = quartz. t = tripwire. s = string.
Then, place redstone like an outer ring. Place a command block that connects to all the redstone. Use the above commands to teleport the player into the arena.
tl;dr: so sad too bad
