This is an idea I had for @Blake_the_GOD’s bedwars map so I’m just gonna make a guide to make life easier for them. But you can still use this guide if you aren’t Blake!
Appearance
1: Get a circle barrier and color it any color and turn off the collision.
2: Make the slightly larger than the player.
Mechanics
1: Put a teleporter inside the bubble. Then make another teleporter and connect
them to each other. Make both teleporters not visible in-game.
2: Put the teleporter far away from the regular map and build a strange, circle shaped room around it.
Finally, make a zone somewhere in the room that when a player enters it, they get teleported back to the regular game.
If this guide was boring and not helpful in any way, please say so in the comments.
