Chunk RandomBlock Challenge
A fun and challenging Fabric mod that restricts your movement and survival to a single chunk at a time, while randomizing the world as you explore.
🚀 Features
1. 🧱 Chunk Randomization
Every time you enter a new chunk, its entire terrain is replaced with a random solid block.
- Smart Filtering: The mod automatically excludes "dangerous" or "fragile" blocks. No more falling into gravel or sand, and no torches or grass floating in the air.
- Solid Selection: Includes full blocks, slabs, fences, walls, stairs, and glass.
2. 🚫 Mining Restriction
You are only allowed to break blocks within the chunk you are currently standing in. Trying to break blocks in neighboring chunks is blocked with a message.
3. ⏱️ BastiGHG Style Timer
A built-in timer displayed in the Actionbar (bottom-center) tracks your challenge progress.
- Starts and pauses synchronized with the game challenge.
4. ⌨️ Commands
/start: Resumes the timer and activates all challenge rules (randomization and mining limits)./pause: Pauses the timer and allows normal block breaking/exploration.
