zzufix
A very simple 1.21+ Minecraft plugin that restores certain behaviors from 1.8 SportPaper and vanilla servers.
Remove TNT offset
Prevents TNT blocks from moving to the sides a bit when primed (while keeping custom projectiles such as those from PGM functional).
Pair this with
fixes:
prevent-tnt-from-moving-in-water: true
in your root/config/paper-world-defaults.yml file for maximum PGM TNT action.
Restore damage and knockback from thrown projectiles
Restores 1.8 behavior for thrown snowballs and eggs (including the new types), which means it makes them deal a bit of damage and give knockback to other players.
Restore arrow self hits
Restores 1.8 behavior which allowed you to hit yourself with arrows and get knockback. Useful for 2 Player Parkour maps.
