? ChunkMirror

ChunkMirror is a highly optimized builder's utility plugin that allows you to instantly replicate blocks across multiple chunks. Place a block in your current chunk, and it will be perfectly mirrored at the exact same relative coordinates in all surrounding chunks within your set radius!

Perfect for creating massive symmetrical structures, endless labyrinths, repeating pillars, or custom minigame maps in seconds.

✨ Key Features

• Perfect Relative Cloning: Blocks are placed in the exact same spot relative to the chunk borders.
• Synchronized Breaking: If you break a block that was placed by ChunkMirror, it will automatically break all its mirrored copies.
• World Protection: Natural Minecraft generation is completely protected. Breaking a natural stone block will not destroy stone in other chunks. The plugin only breaks blocks it explicitly mirrored!
• Lag-Free Placements: Bypasses standard block physics (like sand falling or neighbors updating) during the cloning process, ensuring your server TPS stays perfectly stable even when cloning hundreds of blocks.
• Customizable Grid: Adjust how far the mirroring effect spreads in real-time via commands.

?️ Commands & Permissions

• /cm radius <number> - Set the chunk replication radius (e.g., 3 means a 7x7 chunk grid). Max safe limit is 50.
• Permission required: chunkmirror.admin

⚠️ Technical Notes

• Memory Optimization: To keep your server fast, the mirrored block tags are stored in the server's RAM (Metadata). This means that if you restart your server, previously mirrored blocks will "forget" their link and will no longer break simultaneously. This is ideal for active building sessions!
• Requirements: Spigot, Paper, or Purpur.
• Version: 1.21.x
• Setup: Simply drop the .jar into your plugins folder and you're ready to build!
