Adds a configurable block wall around each dimension. This mod was created for my modpack, but since I created it because I couldn't find a mod like it, I decided to upload it for anyone else in a similar bind. Generates a json config on startup, where block and radius can be changed per dimension. Default is bedrock with 250 radius around every dimension.
I don't believe modded dimensions can be added via the config, although never hurts to try.
I am not a programmer, this mod increases world creation time a decent amount, and probably bugs out if you set the radius too high. Originally pulled the world border position to generate the wall, which of course led it to trying to generate billions of bedrock blocks during world creation. No longer runs off the world border command. And chat gpt 4o-high is more of the mod author than I am.
Created for a modpack, feel free to use in a modpack.
