I'm replying to an old comment, but the code is a mess lol! I made a data structure to hold all the dialogue sequences, but I didn't include a way to add extra information besides who's talking, what they're saying, and what sprite they're using. This meant that whenever I wanted something unique to happen (like a change in scene), I'd have to find a way to hard code it.
For example, there's a bunch of Mia sprites that are just repeats of other Mia sprites, and I'd use them to trigger events in-game. My code was something like:
if (mia.image_index == 5) change_scene("outside")
The system doesn't scale well, it won't allow for different paths, and can't handle unique events at all, but it was my first time doing something like this and we only had two days to make the whole thing, so I'm happy it still gets played. Thanks for playing by the way!
