XP SMP Datapack
I don't know my version or loader
Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.
No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.
XP SMP Datapack
About
A datapack used for the XP SMP that makes it so every level you get you gain a heart. But there's a twist: every so often you lose a bit of xp.
Tips
- Try to get high level quick because when your level is higher you lose xp slower.
Installation
Installed just like any other datapack. A tutorial on how to do that can be found on the minecraft wiki here.
