"It's pointless, you fools! You cannot dampen my positive energy!"

This is a plugin for mod makers who want to manually set the face sprite that shows up when a party member has a particular state (emotion) and gets damaged. To do this, add the note "<StateDamageFaceIndex: X>" to the state data, where X is the index of the sprite sheet row to use. If X is -1, then this will disable the damage sprite (secretly this just sets the damage sprite to the same as whatever the current sprite is at the time). It works like any other mod, so just enable it along with your mods that use it.

Alternatively you can take the plugin script and directly include it with your mod. However, this may conflict with other mods if they use different versions of the plugin. Use only the latest version of the plugin to minimize headaches.
