Custom Watermark
Custom Watermark puts a line of customizable text on the game screen, filled with live values such as FPS, health, time, date, coordinates and the Moon phase.
What it does
Players build the watermark text through a built-in GUI. Placeholder tags inside square brackets are replaced with live values, so a line can show frames per second, current health with decimal places, the system clock, the date and the player's username. Coordinates for x, y and z are available as separate tags, and a Moon phase tag can display the phase as text, such as Full Moon, or as a number.
Only the client needs the mod, so a player can add it to a single-player game or a multiplayer client without any change on the server. Files are published for Fabric only, across five release versions, 1.21.4 – 1.21.8. Installation requires Fabric API. The code is open source under the GNU General Public License v3.0 only, and the source, issue tracker and wiki are public, and the wiki lists the full set of tags.
Key features
Custom text watermark
A watermark line is written in a built-in GUI and placed on the screen, so no config file editing is needed.
Live frames per second
The current FPS appears in the watermark, for example 144 fps, updated while the game runs.
Health with decimals
Current player health is shown with decimal places, so partial hit points are visible on the screen.
Time, date and username
The system clock, the current date and the player's username can each be inserted as a tag.
Coordinates and Moon phase
X, Y and Z coordinates are available as tags, and the Moon phase can be shown as text or as an integer.
