Copycat Sails and Compat
Java mod listed for Minecraft 1.21. Downloads from the MC Java Mods app on Android.
⬇ Download on CurseForgeThe author built this one for Minecraft 1.21.1 on NeoForge. On other versions it may install and then do nothing.
The weights of all copycats + blocks is now calculated based on their volume and the base weight is reduced drastically.
This mod also adds a configurable Copycat Sail and Symmetric Sail Block.
You can set drag and thrust power for the symmetric copycat sail block.
As well you can set lift and thrust power for the "normal" copycat sail block.
Values can be set in the config (configurable via the create config editor)
This mod also fixes all bugs i noticed when playing with copycats+.
Once you changed produced drag/lift/thrust make sure to restart your world/server.
