Minecraft offers a useful debug menu (F3) that allows anyone to easily see their coordinates in the world. This makes it easy to save points of interest and share locations with friends (or enemies).

However, not all multiplayer servers want coordinates to be so easily accessible. /gamerule reducedDebugInfo can administratively hide coordinates from the F3 menu, but it is trivial for a player to add a client-side mod that shows them.

CoordinateOffset is a plugin for Spigot and Paper servers that modifies every coordinate in packets between the server and client. The player still sees the exact same world they would normally see. But no matter which mods they install, they cannot see their real coordinates.

Features

• Fully-configurable, flexible methods of determining how to apply offsets
• Randomize offset when the player joins, dies, or changes world
• Match offsets to the player's position, so they see themselves near the world's origin
• Persist the same offset every time a player joins so that they don't notice coordinates changing
• Configure different offsets per-player, per-world, and with permissions
• Extensible API to flexibly get and set offsets
• (Beta) Compatible with ViaVersion, ViaBackwards, BungeeCord, Waterfall, and Velocity

Requirements and Installation

• Spigot or Paper (recommended) for Minecraft 1.17.x, 1.18.x, 1.19.x, 1.20, 1.20.1, 1.20.2, 1.20.3, 1.20.4, 1.20.5, 1.20.6
• PacketEvents (for Spigot) v2.3.0 or higher
• An understanding of the implications of installing this plugin.

After ensuring that you meet the requirements, just grab the latest release and drop it in your server's plugins folder.

Configuration, Commands, and Permissions

Please see the Readme and Configuration Guide on GitHub for more details about how to configure and use the plugin.
