Description

🌪️ Chaotic Chunk Randomizer (Chunk Chaos)

Have you ever wanted to walk across a peaceful meadow only to have the ground instantly morph into a massive crater of TNT, a sea of anvils, or a glowing floor of magma? This add-on brings absolute unpredictability to your Minecraft Bedrock survival experience!

❓ What Does It Do?

Every time a player steps into a brand-new, previously unvisited chunk, the terrain automatically and instantly transforms into one of over 30 completely random block types. Every step is a gamble!

✨ Key Features

  • Instant Terrain Morphing: The add-on tracks player movement and randomizes the entire 16x16 chunk area the exact moment you cross the border.

  • Safe Replacement System: Worried about suffocating in a solid block of diamond? Don't be! The script specifically targets and replaces natural terrain (dirt, grass, stone, deepslate, sand, etc.) while leaving air and empty spaces alone.

  • Lag-Protected Engine: Built purely with the modern @minecraft/server Scripting API. To bypass the game's block-fill limits and prevent crashes, the add-on utilizes a custom background queue that processes block replacements in lightning-fast micro-batches.

  • Multiplayer Ready: Fully compatible with multiplayer worlds and Realms. The script tracks every player individually, creating localized chaos wherever anyone decides to explore.

🛑 Important Installation Requirements

To use this add-on, you must configure your world settings correctly:

  1. Supported Version: Minecraft Bedrock 1.21 or higher.

  2. Experiment Toggles: You MUST enable Beta APIs under the Experiments tab in your world settings, or the script will not run.
