An implementation of the Carpet Accurate Block Placement Protocol for Spigot/Paper-based servers. Adds support for FlexibleBlockPlacement from Tweakeroo and easyPlace from Litematica. Never place pistons, observers, or stairs wrong again!
Uses ProtocolLib and is compatible with Spigot/Paper 1.21.x.
First of all make sure to install ProtocolLib: https://www.spigotmc.org/resources/protocollib.1997/
Then just download the plugin and drop it in your "plugins" folder, no configuration needed. https://github.com/shou692199/SpigotEasyPlaceProtocol/releases
For Litematica: Make sure easyPlaceProtocolVersion is set to "Version 2", then build with easyPlace like normal.
For Tweakeroo: Make sure carpetAccuratePlacementProtocol is set to "true", you can then enable and use Flexible Block Placement.
