Everything Is Sulfur Cube
Server-side Fabric mod for Minecraft Java 26.2.
When a player tries to break a block, the block is replaced with a real minecraft:sulfur_cube carrying that block in its body slot. Right-click block placement is not changed.
Players do not need to install this mod on their clients when joining a server that has it installed.
Features
- Converts left-clicked blocks into block-sized Sulfur Cubes.
- Stores the interacted block item in the cube's body equipment slot.
- Prevents the original block item from dropping during conversion.
- Keeps empty Sulfur Cubes visible and unmanaged.
- Supports per-player Sulfur Cube shell visibility for cubes carrying blocks.
- Sends no command feedback to player chat; changes are logged to the server console.
