UUID Hex Mod FAQ
10 questions players actually ask, answered.
How do I get started with UUID Hex Mod?
Install the mod, then run the `uuid:_` function as any entity to automatically capture and convert its UUID to hexadecimal format. The result appears in `storage uuid:out plain` and is ready to use immediately.
What's the difference between using uuid:_ and uuid:convert?
`uuid:_` grabs the UUID directly from the entity you're running it as, while `uuid:convert` lets you manually input a custom 4-integer array into `storage uuid:in UUID` and converts that instead. Use `uuid:_` for quick entity lookups and `uuid:convert` when you already have UUID data from another source.
Where do I find the converted UUID after running a function?
Check `storage uuid:out plain` — the mod stores all formatted hexadecimal output there as plain text, ready to copy or use in other commands and systems.
Can I convert multiple UUIDs at once?
The mod converts one UUID per function call; you'll need to run `uuid:_` or `uuid:convert` separately for each entity or number array you want to process.
Why is UUID Hex Mod faster than doing conversions manually?
The mod uses a pre-calculated lookup table of hexadecimal values from 0000 to FFFF instead of computing conversions on the fly, which eliminates the processing delay when you need to convert many UUIDs or integrate UUID data into larger systems.
Do I need to format my UUID data in a specific way before using uuid:convert?
Yes — set your UUID as a 4-integer array inside `storage uuid:in UUID` before running `uuid:convert`; the mod expects this exact format to process the conversion correctly.
Will UUID Hex Mod work on a multiplayer server?
Yes, UUID Hex Mod works on both single-player and multiplayer servers; install it server-side and all players can use the functions to convert entity UUIDs.
Can I use converted UUIDs in command chains or datapacks?
Yes — the hexadecimal output stored in `storage uuid:out plain` is plain text that integrates seamlessly with other commands, functions, and datapack systems.
What happens if I run uuid:_ on a non-entity or invalid target?
The function will fail silently or produce no output; always make sure you're running `uuid:_` as a valid entity with an actual UUID.
Does UUID Hex Mod affect game performance or TPS?
No — the mod is designed to be lightweight and uses pre-calculated data, so it has minimal impact on server or client performance even when converting UUIDs frequently.
