📝 Changelog - v1.0.0 (Initial Release)

✨ Features & Additions:

  • Initial Launch: Welcome to Chunk Chaos!

  • Dynamic Chunk Detection: Implemented a real-time tracking system that triggers the exact moment a player crosses into an unvisited 16x16 chunk.

  • Massive Block Pool: Added a randomized pool of over 30 chaotic blocks (including TNT, Anvils, Slime, Diamond Blocks, and more) for terrain transformation.

  • Safe-Swap Technology: Engineered the replacement logic to only target natural terrain (dirt, stone, deepslate, sand, etc.) to ensure players do not suffocate inside solid blocks or lose empty air space.

  • Chat Notifications: Added a personalized chat broadcast that alerts the player of the specific block type generating beneath them upon entering a new chunk.

⚙️ Technical & Performance:

  • Engine Requirements: Built fully on the modern @minecraft/server Scripting API (v1.11.0). Requires Beta APIs experiment to be enabled in world settings.

  • Lag Mitigation System: Integrated a custom background command queue that processes block fills in micro-batches (maximum 6 per game tick). This bypasses the game's standard volume limits and prevents server crashes during massive terrain shifts.

  • Vertical Chunk Slicing: Divided the chunk-filling logic into three vertical Y-coordinate zones (Y: -64 to 63, Y: 64 to 191, and Y: 192 to 319) to ensure seamless, total coverage from the bottom of the world to the sky limit.
