From what I've seen some languages like Python (I think) let you do, I don't know the proper word, 'live' debugging by keeping a little window of what you're working on open as it's been written.
SO: I was wondering if it was possible with ss13/dream maker, but I'm too afraid to ask and make a fool of myself in a discord I'm in.
I don't think you can because the game is sort of instanced with one thing running at the beginning of every round. So you'd need to compile the whole thing each time anyway, I think?
