CoopTweaks
Sync advancements, chat relay for Discord and more. Check here for the latest builds.
About
This project is inspired by the CooperativeAdvancements mod, my
goal with this is to add on the coop experience I really enjoyed from CooperativeAdvancements by giving more features in just one package.
Some features in this mod come from my other mod, Fred.
Features
- Bridges a Discord channel to the Minecraft server chat, allowing for chat between the two.
- Send events like advancements, join/leave, death, from the server to Discord.
- Sync advancements completion, all players share the same advancement progress.
- Discord commands to retrieve information about the server.
- Link items in the chat.
TODO
- More options to enable/disable certain parts of the mod.
- Add Discord commands to retrieve general information about the server, TPS, etc.
- Maybe use a small database library for storage as it might be useful for other ideas.
