Versions
Retina is a raycasting library data pack for Minecraft: Java Edition 1.20+, using voxel traversal.
Unlike other similar packs, it supports (almost) all of the different hitboxes, including both blocks & entities. It also doesn't rely on entity teleportation, meaning it runs slightly faster on average too.
Additionally, Retina supports a lot of customizable input parameters and gives detailed output information, making it a very useful resource for custom maps and datapacks, with applications ranging from magic wands to guns to custom block placing to laser beams.
For more specific information, check out the GitHub repository.

## What's Changed
### Technical Changes
- Updated for compatibility with Minecraft 1.21.5
- (IMPORTANT)** Previous Minecraft versions are no longer supported
- Implemented hitboxes of Minecraft 1.21.4 - 1.21.5 blocks & mobs
- Pale moss carpets, pale hanging moss, bushes, cactus flower, short and tall dry grass, leaf litter, wildflowers, and creaking
### Technical Changes
- Block and entity hitboxes are now stored using floats, so that the scale factor can be easily changed and everything will *actually* react to it.
- Step counts in debug messages now show the correct number.
- Full Changelog**: https://github.com/Nico314159/Retina_v2/compare/v2.4.0...v2.4.1
