HitboxChanger
by JO1LL
HitboxChanger lets players show, color and reshape entity hitboxes on the client, with separate settings for each entity type.
What it does
Installed on Fabric with Fabric API and WalksyLib, HitboxChanger is a fork of another hitbox viewer. A global toggle turns rendering on or off, hitboxes can be drawn automatically when the game launches, and each entity type has its own visibility switch.
Outlines can be customized in color, thickness and gradient, and highlights can mark entities that are taking damage, sit within interaction range, or are under the crosshair. Fills follow the same options and add a hover highlight. A look vector shows the view direction with an adjustable length, width, color and directional arrow, and living entities can be drawn at eye level. Hitboxes near the camera fade smoothly, the player's own hitbox can be hidden, and the hitboxes can be limited to players flying with Elytra.
The mod is client-side only, so servers run without it. It is released under All rights reserved and is not open source. Fabric files cover 1.21.4, 1.21.10, 1.21.11 and 26.2, with 1.0.0-26.2 as the latest file for 26.2.
