I've been working out and implement a more robust system for handling character art in the VN conversations.
I needed a system that can account for different versions of an NPC (like the masculine or feminine versions of that first Imp Guard), and a way to have a NSFW/SFW art setting. And now I have a big ol look up table for all the art.
All the main pose's index values have been standardized too. So instead of every character having their own list of poses, 13 for every character is going to be 'flirt' (assuming that cel is not left blank lol.) There is also a system for poses outside of this table.
Characters can also have multiple banks of art to pull from, so if you have a strong relationship with an NPC, they can have more of a seductive Idle/Talk/Think/Joy/ect pose for a standard convo. All I have to do to have the standard and seductive version of that convo is to change one variable and the code will pick when going though it. There is also code for handing characters making eye contact, since some are really tall and some are really short.
tl;dr
There is now a system for easily handling character art, this will make adding more variety to the NPCs much easier.
