is an excellent tutorial specifically for Gamemaker games. It's what I have been using to dig through the stack for pointers. Unfortunately not having great results. I've written a script that pops st(0) and changes the value, but I must be missing a flag or something because I keep getting access violations and various other errors. Like once it *was* working but it *also* changed time/season.
I will crack this eventually, it is my new life goal... it just may not be this week..(year)
