Accurate Hitboxes

Accurate Hitboxes replaces Minecraft's broad entity hit detection with hitboxes derived from visible model parts. Attacks and projectiles must intersect the model geometry instead of only the vanilla bounding box.

Features

• Per-part hitboxes for vanilla and many modded entities
• Animated hitboxes that follow model movement, rotation, scaling, and entity state
• Dedicated-server synchronization for current rendered geometry
• GeckoLib 4 support when GeckoLib is installed
• Blacklist and whitelist configuration modes
• Green per-part debug outlines with F3+B
• TaCZ bullet compatibility on Forge/NeoForge 1.20.1
• Baby and scaled-entity support

Requirements

Accurate Hitboxes must be installed on both the client and server. Connections without the required server installation use vanilla interaction behavior.

The current mod release supports Minecraft 1.20.1:

• Fabric and Quilt
• Forge and NeoForge

Older releases are available for Minecraft 1.20.2 and 1.20.3.

Configuration

The configuration file is located at:

config/accuratehitboxes.json

Set mode to:

• blacklist to disable accurate hitboxes for listed entity IDs
• whitelist to enable accurate hitboxes only for listed entity IDs

The Ender Dragon and its entity parts are excluded by default because Minecraft handles that boss through its own multipart collision system.

Compatibility Notes

• GeckoLib 4 is detected automatically and remains optional.
• Sodium and Iris use different rendering paths; compatibility can depend on the exact mod versions and shader setup.
• With EMF/ETF custom models, collision and the green debug overlay may follow the underlying vanilla model rather than the replacement model.
• Highly unusual renderers or entities that do not use supported model structures may fall back to vanilla hit detection.
