You feel PB is laggy? Well, that has a reason.
Command Prompt language is interpreted, and not compiled. Making this ingame would be a pain I think, but when making executables, that would be incredible.
Basically PB reads your game's code while in-game and that's consuming for the pc, however, if you compile the code into machine language, that would make the thing go a lot better.
I know TT may see this so hard to do, but I think finding someone that could do it and keep it would worth it.
