ShulkerNoRespawns

ShulkerNoRespawn

A lightweight Paper plugin that completely disables shulker respawns and shulker-based farms,
while keeping Elytra looting fully vanilla.

Designed for Minecraft 1.21.10+, built with Gradle and Java 21.

✨ Features

• ❌ Prevents shulker respawns
• ❌ Breaks shulker / Elytra farms
• ✅ Elytra looting from End Cities remains unchanged
• ✅ Existing and newly spawned shulkers never despawn
• 🌍 Works in all worlds
• ⚡ Lightweight & performant (event-based, no ticking)

🧠 How It Works

1. Only allows shulkers spawned during world/structure generation
   • (SpawnReason.CHUNK_GEN)
2. Cancels all other shulker spawns
   • Prevents duplication, reload, and portal-based farms
3. Marks all shulkers as persistent
   • setPersistent(true)
   • setRemoveWhenFarAway(false)
4. On chunk load, existing shulkers are retroactively made persistent

This ensures:

• No despawning
• No respawning
• No farming exploits

📦 Requirements

• PaperMC (not Spigot)
• Minecraft 1.21.10 or higher
• Java 21
