Lock Dimensions

With this datapack, server operators can use the simple configuration command to enable or disable the nether or the end separately.

When the nether is disabled, the gamerule allow_entering_nether_using_portals will be set to false, preventing anyone from traveling there, and giving a message that says the nether is disabled if someone touches a portal block. Any player already in the nether, when it gets disabled, or who gets there through some way other than a nether portal, will be sent to their spawn point (unless their spawn point is in the nether) and shown a message that says the nether is disabled.

Unlike nether portals, end portals can't be disabled simply with a gamerule, when a player enters the end portal while the end is disabled, they will be sent to their spawn point and shown a message that says the end is disabled.

Currently has no support for disabling dimensions aside from the nether or the end.

To open the configuration, run the command /function lock_dimensions:config with operator permissions.
