Diamond Hitbox
Diamond Hitbox replaces the generic bounding boxes vanilla Minecraft gives entities with hitboxes taken from each model's JSON.
What it does
Each entity's collision area is rebuilt from the exact shape of its Blockbench model, so what a player sees on screen matches what the game tests when a hit lands. The mod runs on Fabric, is published for 1.20.1 – 1.21.8 across 10 release versions, and needs to be installed on both client and server, so every player and the server need it. The code is all rights reserved, not open source.
Key features
Model-matched hitboxes
Entity collision boxes follow the exact outline of the custom JSON model instead of a broad vanilla box.
Lighter than bulky boxes
Generic bounding boxes are swapped for tailored ones, which trims the extra space that makes combat feel off.
Blockbench model support
Hitboxes are read from Blockbench JSON models, so custom mob and entity models get accurate hit areas.
