LUKAS' CHUNK OBSERVER

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

Evidence

Ran on Kiln's test stand (2026-11-04): LukasChunkObserver did not start: java.lang.NoClassDefFoundError: net/fabricmc/fabric/api/event/lifecycle/v1/ServerLifecycleEvents.

What it needs from Kiln

  • Mixin
  • net.fabricmc.fabric.api.event.lifecycle.v1.ServerLifecycleEvents
  • net.fabricmc.fabric.api.event.lifecycle.v1.ServerLifecycleEvents.ServerStarting
  • net.fabricmc.fabric.api.event.lifecycle.v1.ServerLifecycleEvents.ServerStopping
  • net.fabricmc.fabric.api.event.lifecycle.v1.ServerTickEvents
  • net.fabricmc.fabric.api.event.lifecycle.v1.ServerTickEvents.EndTick
  • net.fabricmc.fabric.api.networking.v1.ServerPlayConnectionEvents
  • net.fabricmc.fabric.api.networking.v1.ServerPlayConnectionEvents.Disconnect
  • net.minecraft.server.MinecraftServer
  • net.minecraft.server.network.ServerGamePacketListenerImpl
  • net.minecraft.server.players.PlayerList
  • net.minecraft.world.level.ChunkPos
  • net.minecraft.world.level.storage.LevelResource
  • ServerPlayer.chunkPosition()

On the roadmap: Code next to data (0.3), Mixin (0.5)

In the author's words

A lightweight, server-side Fabric mod that logs how long each player spends in every chunk to an SQLite database - the raw data for activity heatmaps.

Scan

Scanned on 4 November 2026 against Kiln 0.2.0, file lukaschunkobserver-26.10.1+26.3.jar. The scan reads the mod's classes; it does not run them.
