Looping World mod takes the hard edges off the world border. Step too far, and you'll be teleported to the opposite side of the map, creating a seamless, looping world.
It teleports the player by calculating their position relative to the world border and mirroring it to the opposite side:
It always finds a safe spot, prevents fall damage, and avoids dangerous blocks. Works completely server-side and fits any existing world — just enable the world border.
Perfect for small maps, survival challenges, adventure maps, or experimenting with new world designs.
Note: In the Nether, players are teleported to the roof, so make sure you have a way to get back down.
