I'm new at renpy and i'm trying very basic stuff. I have a basic imagemap with buttons that trigger scenes. What I want to do is make it so every time i do something I advance from day to afternoon to night and the map displays the appropriate background. As I said im new, so at the very least I would like to know where to start because the tutorials i see online confuse me a bit.
