About the mod

World Border is a minimalistic configurable mod which allows the creation of a configurable world border, limiting the world size. This can prevent infinitely large file sizes or keep a community of players closer together. You can also loop around the world when hitting a world border, configurable in the config. This will teleport you to the negative coordinate if you hit the positive border and vice versa. Makes for infinitely looping worlds while still limiting the size.

Looping works like this:

Looping in the nether uses clever code to not end up in lava or on the nether roof.

World Border server crashes on startup – what to do?
