Universal Player Data

Calls something that is on Kiln's roadmap. Parts of it may already run.

Evidence

Ran on Kiln's test stand (2026-11-04): UniversalPlayerData did not start: java.lang.NoClassDefFoundError: org/apache/commons/lang3/Validate.

What it needs from Kiln

Mixin
net.fabricmc.fabric.api.entity.event.v1.ServerPlayerEvents.Join
net.fabricmc.fabric.api.entity.event.v1.ServerPlayerEvents.Leave
net.minecraft.world.level.portal.TeleportTransition
net.minecraft.world.level.portal.TeleportTransition.PostTeleportTransition
org.apache.commons.lang3.Validate
ServerPlayerEvents.JOIN
ServerPlayerEvents.LEAVE
ServerPlayer.findRespawnPositionAndUseSpawnBlock()
ServerPlayer.teleport()
LivingEntity.stopRiding()

On the roadmap: Minecraft's libraries and client API (0.2), Code next to data (0.3), Mixin (0.5)

In the author's words

Player data is shared between all worlds

Scan

Scanned on 4 November 2026 against Kiln 0.2.0, file universal-player-data-0.2.1-fabric-26.1.2.jar. The scan reads the mod's classes; it does not run them.
