Modify Player Data

This mod allows Minecraft's data commands (/data, /execute store, etc.) to modify player data.

Alongside supporting most vanilla player NBT tags, this mod also adds the CustomData NBT tag, which can be used to store any type of NBT data on a per-player basis.

Feel free to report any bugs, or suggest new features, at the issue tracker.

I try to keep support up for the latest major and latest minor release of Minecraft. Updates to newer Minecraft versions may be delayed from time to time, as I do not always have the time to immediately update my mods.

Unsupported versions are still available to download, but they won't receive new features or bugfixes.

Usage

Mod builds can be found here and on Modrinth.

The Fabric API is not required. This mod is not required on clients.
