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.
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.
