HeightBoxLib
by Trunkis
HeightBoxLib is a library for reading an entity's hitbox height, eye position and anchor points, and it is aimed at data packs and mod authors.
What it does
Hitbox related values from the library can be read for any entity, including the height of its hitbox, the position of its eye and the anchor used for aiming. Those values are written to hblib:hitbox storage and to scoreboard objectives such as Eye, hblib.number and Total, so a data pack can use them in commands. The library also lets an entity face the torso of a player. It is published for Fabric, Forge, NeoForge and Quilt, and as a data pack, with files for 1.20.3 – 26.2 and 3+mod for 1.21.4 as the latest file. The server requires it and the client may leave it out, and it is released under the MIT License, so it is open source.
