TheTrackers

Each tracked entity can be marked with a cursor placed on the screen edge or in a central surround area, so flying mobs such as the Ender Dragon and Wither can be located while they move through walls or across the view. The default setup includes tracking cursors for these bosses, and the mod exposes a tracking list where each entry pairs an entity type with a cursor style.

Tracking can be toggled, cursor size adjusted relative to the global size, and the number of tracked entities capped at 10 so the display stays readable. Only the nearest entities within that count are shown. The projection used in central surround mode can be chosen, with Aitoff recommended for typical use.

The mod is built to work together with Confluence, and the author describes it as a submodule within the Otherworld project. Files are published for 1.20.1 and 1.21.1, with the 1.20.1 and 1.21.1 builds both at version 0.2.6. Players add it to their own game, and a server needs no copy. The code is released under the GNU Lesser General Public License v3.0 only and is open source, with the source, issue tracker and wiki public.
