A script were if you loose health you can press a button so your character starts applying a bandage to himself and you get health as it happends. It It would also be cool if there was a way to make a script where you can have injuries. For example if your health goes very low the script could change the walking style to an injured style. The script could also change the vision style so that it would look more realistic.
Sorry my english is not that good, but i hope you understood it reading this.
