Border cords checker
by AnTyBuPyC
Border cords checker shows the world border's coordinates, center, radius and cardinal direction in the game's debug menu, even when cheats are off or the border is not rendered.
What it does
On the client, the mod reads the world border and adds its details to the F3 debug screen. It works whether the border zone is drawn on screen or not, and cheats do not have to be enabled. Values update as the border changes, so the center, radius and direction always reflect its current state.
The mod also provides a command, bordercheck, that displays the world border coordinates in chat. Because it only runs on the client, a server owner does not need to install anything, and players on any server can use it while playing. It works correctly alongside the BetterF3 mod, which extends the same debug menu.
Installation needs Fabric API on Fabric. The files target Minecraft 1.21.8 only, and the mod is released under the MIT License. The source code is public, and the mod is open source.
