Logic Gate
Logic Gate adds one toggleable redstone component that can be set to several logic functions, from BUFFER to XOR, NAND and NIMPLY.
What it does
The gate has a single-input mode and a double-input mode. In single-input mode it acts as a buffer or a negation. In double-input mode the left and right sides feed the gate, and the output follows the selected function. Right-clicking cycles through the modes in order, and holding Shift reverses that order. A newly placed gate starts in the default mode.
Gate delays are configured separately for each mode. Settings are changed with commands on the client and on the server. The Mod Menu integration gives a client-only settings screen, and that screen becomes richer when Cloth Config API and YetAnotherConfigLib (YACL) are also installed. Fabric API is required.
Logic Gate runs on client and server, so the server and every player need it. Files are published for Fabric and NeoForge across 24 release versions, 1.20 – 26.3, under the MIT License, and the project is open source with public source code and an issue tracker.
Key features
Toggleable logic modes
One gate block covers several functions, switched by right-click instead of separate crafting recipes for each.
Single and double inputs
Single-input modes include BUFFER and negation, while double-input modes use the left and right sides.
Reverse cycling
Holding Shift while right-clicking steps through the modes in reverse order.
Per-mode gate delays
Each logic mode has its own delay, set with commands on the client and server.

Use cases
Compact circuits
One block replaces several gate types, which can shorten redstone builds that would otherwise need many separate components.
Who it’s for: Redstone builders who want several logic functions in one component, and server owners who need consistent gate settings through commands.
