SwingThrough — Forge Port for Minecraft 1.20.1

Allows targeting living entities through transparent blocks.

SwingThrough discards the block crosshair target when the block has empty collision, the entity is living and attackable, you're not riding it, and it's within reach — so you can hit entities through grass, crops, and flowers instead of swinging at the block.

This branch is a Forge port for Minecraft 1.20.1 with the full original logic ported from the upstream 1.20-era GameRenderer mixin (Mojang pick, the crosshair picking routine).
