This weekend I've mainly been working on modifying the dialogue system to make it more flexible, and adding some more triggers that people have suggested. Rather than add specific triggers for her thinking or him talking though, I'm going to add optional "styles" for the dialogue box, which will simply look different and ignore any mouth animation. Lines will default to the current speaking style unless you add an extra tag in the dialogue text file.
I also spent some time updating the tutorial for making dialogue mods, because it's fairly out of date now, and I've added a viewer for it in the actual game. I think it would be interesting to add a tool for creating dialogue files in game too, to help automate the process. Is that something people would find useful?
