What's new

📜 OneSpawner v13.1 — The Block Protection Hotfix

🛠️ PRECISE CORE PROTECTION

  • Standard Spawners Unlocked: Patched an overly aggressive anti-griefing check that accidentally prevented players from breaking any spawner in the game. Players can now mine, break, and interact with regular mob spawners freely! The unbreakable protection now exclusively locks down the exact, registered Core Spawner.

  • Platform Radius Fixed: The unbreakable block protection for Deepslate Bricks and Nether Bricks has been strictly localized. It now only protects the exact 5x5 arena platform directly underneath the Core Spawner (specifically checking the Y=63 layer within a 2-block radius). Players can now build with and break these brick types normally anywhere else in the world.

  • Piston Logic Updated: Piston extension and retraction events have been updated to check exact database coordinates, ensuring players can use pistons on regular spawners and blocks without triggering the Core Spawner's anti-griefing lock.
