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 Paper-based Minecraft 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.

Why? ---- This plugin isn't intended for all servers. Here are a few ideas that might make CoordinateOffset useful: * Center the origin: If you consider coordinate usage and sharing to be metagaming, this prevents it. * Center the origin: Coordinates no longer outclass compasses, lodestones, recovery compasses, and maps when those coordinates are inconsistent. * Center the origin: If everyone sees different coordinates, players cannot derive each other's coordinates from an accidental leak in a screenshot. * Center the origin: Any unknown offset makes seed-cracking tactics harder. * Center the origin: Put the (0, 0) coordinate anywhere you'd like.

Features

* Fully-configurable, flexible methods of determining how to apply offsets * Generate offsets randomly for each player, or use fixed offsets for multiple players * Match offsets to the player's position, so they see themselves near the world's origin * Optionally regenerate offsets based on various player actions, including death, world change, teleport, and server join * Regenerate and set offsets immediately with commands * Configure different offsets per-player, per-world, and with permissions * Automatic scaling for offsets to ensure coordinates still align when using a nether portal * Extensible API to flexibly get and set offsets * Compatible with Distant Horizons, ViaVersion, and Velocity *(must be installed on Paper, not Velocity itself)*

Requirements and Installation

* An understanding of the implications of installing and incompatible plugins — this plugin WILL break things. * %%MD1%% or a fork for Minecraft 1.21.4–1.21.11 * %%MD2%% (latest release or %%MD3%% for Spigot)

Some known incompatible plugins are: Most anticheats, Geyser.

After ensuring that you meet the requirements, just grab the latest release and drop it in your server's `plugins` folder. Then follow the steps below to configure how coordinates are shifted for each player.

Configuration

*Main article: Configuration Guide*

The main configuration file is automatically generated after the first run at `plugins/CoordinateOffset/config.yml`.

```yaml defaultOffsetProvider: random ```

The default configuration contains five predefined "offset providers". An "offset" refers to the amount that the player's coordinates should appear to be shifted from their real location. Get started by picking a strategy that matches the type of offsetting you're trying to achieve: * `constant` - Specify the exact offset you want players to have. * `disabled` - Players will see their real coordinates. * `random` - Individually randomize each player's offset. Optionally re-roll offsets upon player actions. * `zeroAtLocation` - Use an offset based on the player's starting location, so they see themselves near (0, 0). Optionally re-center offsets upon player actions. * `permission` - Assign permissions to players, like `coordinateoffset.offset.160.-240`, to control their offset.

You can customize these providers further, use different providers for different players/worlds/groups, and define your own providers. See the complete **Configuration Guide**.

Commands and Permissions

API --- You can use or extend CoordinateOffset in your own plugin by using the API. Please see the API Guide.
