Blocks Is Sulfur Cubes
by kikfrem
Blocks Is Sulfur Cubes turns blocks that players left-click into block-sized Sulfur Cubes, carrying the original block as their cargo.
What it does
When a player left-clicks a block, the mod converts it into a Sulfur Cube of the same size. The block item is stored in the cube's body equipment slot, and the original block item is kept from dropping during the conversion. Right-click block placement is changed as well, so a cube can be set down again.
Only the server needs the mod, and players can join without installing it, but the server still sends per-player entity metadata through a server-side mixin, and a custom client networking layer is required for that. Empty Sulfur Cubes stay visible without being managed. Each player can choose shell visibility for cubes carrying blocks, and those choices are saved per UUID in a config file that is created on first start. Command feedback goes to player chat and changes are written to the server console.
The mod requires Fabric API and runs on Minecraft Java 26.2 with Fabric Loader 0.19.3 or newer. It is released under the MIT License and is not open source. Only the 1.2.0 file for 26.2 has been published, on the beta channel, dated 2026-07-06.
Key features
Left-click conversion
A left-clicked block is replaced by a Sulfur Cube of matching size that carries the block inside.
Body slot storage
The interacted block item is kept in the cube's body equipment slot, so it can be recovered from the cube.
Per-player shell visibility
Each player can decide whether cubes carrying blocks show their shell, and the setting is stored per UUID.
Break-attempt replacement
Breaking a block with a left click does not remove it; the block is swapped for a working Sulfur Cube that carries it inside.
