Test Emotions
I personally don't have anyone around that I can test with as I normally don't even play this game I'm just messing with it.
Could someone test these with another person and see if they as well see the emotion in the characters face or if it's just client side.
player_emotion mild
player_emotion smile
player_emotion happy
player_emotion hostile
player_emotion angry
player_emotion blink
player_emotion hurt (This one is hilarious on evie)
Oh, there is also:
cute
wink
haughty
That I found hidden away (never implemented I guess)
Most of those are chat commands, you can find them in chat_commands.txt
A lot of the facial expressions are used during animations but you barely see them since you don't get to see the character's face most of the time.
