hitbox/partikel manger

Players choose the colour of the drawn hitbox, and its line width can be set anywhere from 1 up to 4; the entity under the crosshair receives a colour of its own, an optional glow outline, and a model that can be tinted. Its own box is recalculated from the interpolated position, so it stays on the model instead of lagging behind it. Vanilla's hitbox display is switched off while the mod is enabled, though F3 + B still toggles the vanilla display.

Particles can be hidden one type at a time from a searchable list, or a whole explosion cloud can be removed with one click, End Crystals included. Each category gets its own toggle for players, mobs, objects, crystals, boats and minecarts, and the debug overlays that vanilla ships, including the flat red eye line and the direction and velocity arrows, are turned off while the mod is active. Blocked particles are never created, so the simulation cost is saved as well.

Hitbox/Partikel Manger requires Fabric Loader 0.16.0 or newer. It is published for Fabric only, across 1.21.8 and 1.21.11 with the latest file for 1.21.11, and it is released under the MIT License. It is installed on the player's side alone, so servers need nothing.
