Since I have 8 different emotions for each of my main characters, I was wondering if there'd be a way to make it so that whenever their health improved (healed) in battle, their face graphic would turn into a happy one of my choice then switches back, and when loses health (attacked) in battle, their face graphic switches to an angry or hurt face of my choice then switches back into the normal face graphic. ;8

I've not looked at it or anything, so I have no idea if it's any good, but it seems to have the purpose you desire.
