Short Circuit
Short Circuit lets players build compact, modular redstone circuits inside a single block, with tools for shaping and labelling them.
What it does
A circuit is built inside a block whose six walls are labelled U, D, L, R, F and B. Players mark which sides carry input and which carry output by crouch right-clicking a wall with a Poking Stick, then place the circuit's interior. External redstone signals enter through the input faces and leave through the output faces. Once the build is finished, the inside can be hidden by crouch right-clicking the circuit, which keeps the view clean on large projects. The exterior size is set with the same stick and cycles between 4 and 256, using powers of two only.
Four items are craftable with the mod: the Poking Stick, the Labelling Stick, the Truth Assigner and a circuit memory component. Delay blocks can be added on purpose, so timing is controlled rather than left to chance. A Bad Apple demonstration built with the mod is included among the author's examples. Because many dynamic circuits rendering at once can cause lag, the author notes that the hiding option is useful in larger builds. Fabric API is required on every loader, and the mod runs on client and server, so both the server and each player need it.
Key features
Modular circuit blocks
Circuits are built inside a six-walled block, with input and output faces set per side.
Poking Stick and Labelling Stick
The two sticks mark faces, set exterior size and label parts during construction.
Truth Assigner
The machine records the output of a dynamic circuit and converts it into an integrated circuit.
Circuit memory component
A memory component is crafted for circuits that need to hold state across ticks.
Hidden interior and delay blocks
The inside of a finished circuit can be concealed, and delays are placed on purpose.
