Description

Accurate Block Hitboxes

Accurate Block Hitboxes creates selection outlines directly from visible block models. Block orientation, state, connections, and open or closed variants are handled automatically.

Features

  • Model-accurate selection outlines for 2D and 3D blocks
  • Pixel-accurate transparency for plants and other cross-face models
  • True diagonal surfaces without staircase-like approximations
  • Thin 2D hitboxes with a thickness of 0.5 texture pixels
  • Support for models with a 3D base and additional 2D parts
  • Seamless outlines for doors, tall plants, beds, and other multi-block structures
  • Optional updates based on the currently visible frame of animated textures
  • Separate Vanilla hitbox whitelist to reduce flickering target switches
  • Projectiles can pass through model holes when their center ray fits through the gap
  • Configurable projectile hole pass-through support

Configuration

YACL can be used to configure the mod, 2D and 3D support, animated textures, additional model parts, and seamless connections. A block blacklist and a Vanilla hitbox whitelist are also available.

Requirements

  • Minecraft 1.21.1
  • NeoForge 21.1
  • YetAnotherConfigLib 3

Notes

  • Player and entity collision remains unchanged; projectiles use the model center ray for supported block holes.
  • Block entity renderers are currently excluded.
  • minecraft:tall_seagrass is blacklisted by default because animated geometry can be expensive to rebuild.
  • Vanilla is the current primary target. Resource packs and modded baked models may work, but are not fully guaranteed yet.
