UUID Hex
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.
✅ Features
- Efficiently converts UUIDs to hex format
- Optimized for speed by relying on a precomputated hexadecimal range (
0000-FFFF), increasing static data usage
📖 Usage
Call the uuid:_ function as an entity and use its output in storage uuid:out plain
Alternatively, assign a 4-integer array to storage uuid:in UUID, then call the uuid:convert function to format it.
