Which Minecraft do you have?

Every version of the game needs its own build. Pick yours, then download — the wrong build installs fine and then does nothing in the game. This mod is built for Fabric only.

Minecraft 1.21.2–1.21.4Newest
Minecraft 1.21–1.21.1

⬇ Download for 1.21.2–1.21.4 ⬇ Download for 1.21–1.21.1

I don't know my version or loader

Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.

No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.

QuasiDusting (Fabric)

Overview

This Fabric mod modifies Minecraft's quasi-connectivity (QC) behavior, making it directional and toggleable by using redstone on a QC affected block. Using this, you can control which faces of QC-affected blocks are influenced by redstone signals a block away!

How It Works

Right-click a QC-affected block with redstone dust on the face you want to be affected.
Shift-Right-click to place redstone dust normally, without modifying the block's QC state.
Quasi-connectivity only activates from the faces where redstone dust has been applied.
This feature allows for easier, sensible, more compact, and more diverse redstone contraptions.

Various applications of this mod.

A variety of examples: The piston and dropper are active because they are quasi-connected to the lever, while the sticky piston is inactive because quasi-connectivity is disabled by default.

Compatibility

This mod should be compatible with most other redstone mods.
However, full compatibility has not been extensively tested.
If you encounter bugs or compatibility issues with other redstone mods, please report them on the Github Page or in the issues tab.
