In the situation I'm building, I'm planning on making the environment outdoors change day/night after a certain amount of time passes. I was wondering if AGS had any potential for time compression, e.g. press a gui button, and it goes through processes twice as quickly, or even half as quickly and I can start things off being fast by default. Something that would make an in-game clock run faster, and (because characters move as each frame changes on anti-glide) the characters end up moving faster/slower.
Or am I limited to manually scripting it so that when the button is pressed, the characters' speed doubles/halves? Sorry if I seem a little unclear, it's that time of the morning.
Open the AGS manual, then search for SetGameSpeed.
