}object sender in this case a button. a.gif and b.gif are sneezing animations (right and left), and 0.gif - 10.gif are emotions. Each time you press k , it increases until it becomes greater than 10. If k is even , it goes one way, if it's odd, the other. After the sneeze animation ends, the Complete function is executed to change the character's emotion.
