Waypoint Compass

Pressing B saves the current X, Y and Z as a new waypoint, and the client confirms the save with a message on the action bar. Saved points are named in sequence, so a spot might read as WP 1 123 64 -512. Pressing N switches which waypoint the compass tracks, and cycling through the saved spots makes moving between several bases simple. Pressing K removes the waypoint being tracked, and the Delete option removes the current pin.

The compass strip shows an arrow pointing back toward the tracked point, with live direction and distance. Distance is measured horizontally on the X and Z axes, so height differences do not inflate the number. Each stored point keeps the dimension where it was recorded: standing in the Nether with an Overworld point selected shows the Overworld point instead of a misleading distance. Pressing H hides and re-shows the compass without losing saved points, and the HUD can be toggled separately.

The mod is a client-only install that works on any server, including vanilla Realms, because the server never sees it. Keys are read directly from the operating system through GLFW, so they are suppressed while a GUI, chat, sign editor or inventory is open and cannot fire mid-type. Fabric API is required, and the mod is published for 1.21.8 – 1.21.11 under the MIT License.
