Implementation of logic gates and BROKEN binary adder in the form of a Source Engine .cfg file
Raw
circuit.cfg
// Logic gate implementation in Source
// Usage:
// 1. Preprocess this file with cfgpp.lua (or use the preprocessed file below this one) and put it in your game's 'cfg' folder (which will be inside a folder with the name of the game, e.g. 'cstrike' for CS:S, or 'tf' for TF2)
// 2. Run the file by putting this in the developer console: 'exec circuit2' (replace "circuit2" with whatever name you gave the processed file)
// initialization (floating pins will break things)
