Thanks. My game is essentially finished, apart from a few small things like this. I want to start on the graphics next. I'm guessing that I'll have to do something special to have a dark room (or blank) image when it's dark and normal image when it's light. Is that correct?
Viewing post in How do you prevent actions in dark room?
By default, all images are disabled in the dark , but I'll also be adding support for custom layouts for dark rooms in the next few days (which will let you have a special graphic per room or fallback graphic) when in the dark state.
For now, accept no image in the dark. I'll let you know when it's ready.
