Custom Cartesians
by 50ap5ud5
Custom Cartesians is a client-side coordinate display for Fabric that shows chosen axes in a separate HUD, useful when sharing screenshots of locations.
What it does
Custom Cartesians adds a coordinate HUD that can show only the Y axis or any other chosen axis, sitting beside the vanilla F3 debug screen without replacing it. The HUD can be toggled off, and a default key combination of Left ALT and H switches the Y coordinate display on and off. Hiding the readout is handy when a player wants to share a screenshot or post a location publicly without revealing where their base sits.
The mod needs Fabric API and Cloth Config API, and Mod Menu is optional; with Mod Menu installed, a configuration screen is generated from the config file. Custom Cartesians runs client-side only, so servers and dedicated server installs need nothing. Files are published for 1.16.5, 1.17 and 1.17.1, with the latest Fabric file targeting 1.17.1, and the mod is released under a custom license with free use for personal play and redistribution limited by the author's terms.
Key features
Axis-specific coordinate HUD
The coordinate display can be customised to show only a single axis, such as Y, rather than all three coordinates.
Toggleable display
The coordinate HUD can be switched off during play and switched back on with the default key binding.
Config file and settings screen
Display options are stored in a config file, and a settings screen is generated when Mod Menu is installed.
Compatibility
Latest build for each game version and loader.
Only full game releases are shown. This mod publishes no snapshot builds.
Use cases
Who it’s for: Players who want a coordinate readout on their own client, especially those who sometimes share screenshots publicly, and modpack authors who need a client-only option.
How it compares
Better Coordinates HUD is server-side only, released under the Apache License 2.0, and supports 1.16.5 – 1.21.11, so it is a different kind of mod. Where Am I? is client-side only, released under the GNU General Public License v3.0 only, and covers 1.21 – 26.3, a version range that does not overlap with Custom Cartesians.
