Is there a way to have this work on singleplayer games like HL2? [Possible suggestion]

[Glonguarus]

I barely use GitHub, so forgive me if this isn't the right place to put this. If this is already a feature I apologize but is there any way to have this work on something like HL2?

Unfortunately no. Until Valve makes VScript functionality on their singleplayer games, it will not happen any time soon.
