Health to Size
Java data pack listed for Minecraft 1.21–26.x. File opened and checked on 22 Oct 2026; downloads from the MC Java Mods app on Android.
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.
Uses the generic.scale attribute introduced in 23w51a to scale the player relative to their health.
