Explanation: Notice that the five buttons we've done
so far have very very similar actions in them. The only difference is the value of the
dragon object's image_speed. The
reason that each of the Set Variable actions specify
"obj_dragon.image_speed" instead of just "image_speed"
is to change the value of "image_speed" inside the obj_dragon
object.
