RandomChunk

RandomChunk server mod

What it does

• Walking into a new chunk flattens and paints that entire plot into a single block theme (sand, stone, deepslate, etc.) with clear headroom for fighting.
• A random guardian mob with buffs and a custom name spawns at the chunk center; killing it drops the glass lock, hands out a brief haste buff, and unlocks progression.
• Red stained-glass walls rise around the chunk at player height, plus particles/sounds that pulse while the arena is active; anyone inside is locked to the plot and teleport-snapped back if they try to cross the border.
• Other players standing in the same chunk are auto-linked to the encounter so parties clear together; locks are cleaned up if guardians die, unload, or worlds unload.

Implementation notes

• Mod id/name: randomchunk / RandomChunk; server entrypoint: com.playergames.plugin.RandomChunkMod.
• Fabric API is bundled inside the jar, so no extra download is required at runtime.
• Each arena caches its anchor Y level for lighter teleports and a tighter, mid-height barrier instead of full-height walls; barriers and particles clean up as soon as the guardian is gone.

Known limitations / ideas

• Large one-chunk repaints can spike tick time on densely populated servers; add a cooldown or cap arena count if needed.
• Walls are glass and destructible; teleporting still enforces the lock, but swap to barrier blocks if you want an unbreakable seal.
• Chunk state is not persisted across restarts, so revisiting a chunk after reboot reshuffles its theme and guardian.
