MapLock - Anti Map Duplication

by darkboyzinho2014

MapLock stops filled maps from being copied in the cartography table, so a map can only be duplicated by the player who locked it.

ForgeNeoForgeClient required, server optionalAll rights reserved1.21 – 1.21.8

What it does

A map owner locks it with the plugin, and the lock is bound to the owner's UUID. Only the creator can reopen the map for copying again. Attempts to copy a locked map in a cartography table return an error. The mod is a Forge and NeoForge build that players install, and the Paper and Spigot plugin is also published. Files exist for 1.21 – 1.21.8 under All rights reserved, not open source.

Key features

  1. Creator-only locks

    Only the player who created the map can lift the lock, because the lock is tied to that player's UUID.

  2. Blocked copying

    A locked map shows an error when placed in the cartography table, so it cannot be duplicated there.

  3. Server plugin support

    The protection is also available as a plugin for Paper and Spigot servers.

Questions

Does MapLock need to be installed on the server?

No. Only the player needs the mod, while a server can run the plugin version on Paper or Spigot. Players need it in their own game, while a server can run without it.

What the author says

This plugin will protect maps that owners set to be uncopiable, giving an error when you try to place it inside a cartography or crafting table. The map creator can lock and only the map creator can unlock it again, its uuid bonded. Any bugs please let me know. Plugin was tested on latest paper server for minecraft…
