Retina

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.
