MECHA - Multiple Entity Collision Hitboxes API

by byteManiak

MECHA adds a Fabric API that lets a custom entity carry several collision boxes instead of one, so developers can give a single entity a more detailed hitbox shape.

FabricClient and serverMIT LicenseOpen source1.19.4 – 1.21.1

What it does

A custom entity class that implements the MultiCollidable interface can override getColliders and return extra colliders, each covering part of the entity's body. The API ships with an example that adds two colliders to an entity shaped like a slab. Version 0.1.2 also introduces DynamicBoundingBoxEntity, whose bounding boxes are built from a list that changes at runtime. The code is released under the MIT License and is open source. Client and server both need the mod, since collision is checked on each side.

Key features

  1. Multiple colliders per entity

    A custom entity can return a list of collision boxes, replacing the single bounding box vanilla entities use.

  2. MultiCollidable interface

    Entity classes implement MultiCollidable and override getColliders to supply the extra boxes.

  3. Dynamic bounding boxes

    DynamicBoundingBoxEntity builds its colliders from a list that can change, added in version 0.1.2.
