Accurate Hitboxes

Accurate Hitboxes dramatically improves Minecraft's combat precision by replacing the game's oversized vanilla bounding boxes with true pixel-perfect geometry.

Core Features

• True Pixel-Perfect Accuracy: The mod mathematically extracts the exact 3D visual geometry of every entity on your screen. If a mob has horns, wings, or a tail, those exact shapes become its physical hitbox.
• Universal Modded Compatibility: Because the hitboxes are dynamically sourced directly from the rendering engine, this mod natively supports nearly all modded mobs and bosses right out of the box with zero configuration required.
• GeckoLib 4 Support: Modded entities powered by GeckoLib (e.g., Naturalist, Alex's Mobs, etc.) get full per-part accurate hitboxes. GeckoLib is detected automatically — no configuration needed, and no crash if it's not installed.
• Sodium & Iris Compatible: Fully compatible with Sodium and Iris shaders. The mod uses a rendering-pipeline-independent extraction system that works regardless of which renderer is active.
• Configurable Whitelist/Blacklist Mode: The config/accuratehitboxes.json file supports a "mode" field that can be set to "blacklist" or "whitelist". In blacklist mode, listed entities are excluded from accurate hitboxes. In whitelist mode, only listed entities receive accurate hitboxes — perfect for large modpacks! The Vanilla Ender Dragon is natively ignored by default to drastically improve multi-part boss interaction. Old configs from v1.1.x are automatically migrated on first launch.
• Dynamic Boss Scaling: The server's built-in combat reach algorithm dynamically scales up to 3x the size of the mob you are fighting. This mathematically guarantees you can physically strike the massively outstretched wings or tails of huge custom dragons without the server falsely rejecting your hits.
• Visual F3+B Debug Tracing: Pressing F3+B actively draws vibrant green geometric boxes tightly wrapped around every physical limb so you can visually verify the mathematical precision of your hits in real-time.
• Baby Mobs & Custom Scaling: Baby animals and physically scaled entities intelligently calculate and draw miniaturized voxel geometries perfectly glued to their miniature frames, preventing ghost hits above their heads.
• Zero-Lag Singleplayer Support: Arrows and sword sweeps will interact accurately with real-time animated limbs and extremities in Singleplayer or LAN worlds with absolutely zero network latency.
• Multiplayer Server Support: On multiplayer Dedicated Servers, the mod perfectly syncs and tracks hitboxes entirely server-side. By utilizing static geometric blueprints combined with dynamic coordinate and rotation tracking, projectiles and arrows enjoy pixel-perfect 3D geometric raycasting natively on the server without causing any server TPS or performance lag.
• Anti-Cheat Safe: The mod includes an automatic server handshake. If you log into a vanilla server that does not have Accurate Hitboxes mod, the mod automatically disables the visual tracking lines and gracefully reverts to vanilla mechanics to ensure you are completely safe from anti-cheat bans.
