WELL, for half life there's this: https://github.com/YaLTeR/BunnymodXT An injector program for HL(and alot of other goldsrc games) that can (sometimes the patterns arent found)allow you to tas goldsrc games, using scripts that execute commands in game, and can(but not yet) be turned into an ingame script (AKA a .cfg file) and played back
here is some basic info on the script layout http://tinyurl.com/HLTASDOX
