Hitbox Dynamics replaces the single vanilla hitbox with real per-body-part hit detection.
Every mob gets separate hit zones for its head, torso, arms and legs, and they follow the mob's animation. Your attack only lands if your crosshair is on an actual body part, so you have to aim. Headshots deal bonus damage, and arms and legs deal less. Damage values are configurable.
Works with vanilla mobs and modded mobs. Includes part outlines, F3 debug info and an in-game config screen.
