DimensionAccess
by UltraLionfr
DimensionAccess lets server operators switch individual dimensions on or off through commands, so players can be kept out of places like the Nether or the End.
What it does
Operators can disable or enable specific dimensions with commands, and the change applies while the server keeps running. The mod is server-side only, so only the server needs it and players join without installing anything. Its config reloads live, which means settings can be changed without restarting the server.
A blocked player is stopped before entering a disabled dimension, rather than being sent back after arriving. The check runs before the teleport happens, which keeps chunk loading and advancement side effects out of the process. Dimension identifiers are suggested automatically as operators type commands. Commands require OP level 2. Files are published for Fabric only, for Minecraft 1.21.1, with Fabric Loader 0.16.9 and Fabric API as the required dependency.
Operators who run survival or adventure servers and want to restrict dimension travel can use it to control access to specific worlds.
Key features
Disable and enable dimensions
Server operators can turn specific dimensions off or back on with commands, without editing world files.
Entry blocked before teleport
Players are stopped before they enter a disabled dimension, so the teleport is cancelled rather than undone.
Live config reload
Settings update without restarting the server, so a change takes effect while players are still online.
Identifier suggestions
Commands suggest valid dimension identifiers automatically, which reduces typing errors.
