The Update List is a Scene plugin that maintains the list of Game Objects whose
preUpdatemethod should be called every frame. Game Objects like Sprites add themselves to the Update List automatically so their animations are processed. You do not normally interact with the Update List directly; instead useaddToUpdateListandremoveFromUpdateListon individual Game Objects.
