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_seagrassis 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.
