Hi!
I was wondering that how can I start a intro scene? I mean with what function?
Function *What?*()
(
blah blah
)
There's no such reserved function type for "intro" or "cutscene".
You start it when you need it and in which room you need it. That depends greatly on details, on what you want to achieve.
You may consider creating a separate room for intro, start game at that room and do actual events inside "after fade in" function. You may use existing room and run intro in "first time enter room" for example.
This may vary, there's no "universal" choice for this.
