public class AnimationInstance extends java.lang.Object implements Drawable
An AnimationInstance is an instance of an Animation that represents a point in the Animation and rates at which that point progresses through the Animation. An AnimationInstance has one level for each dimension of its Animation, numbered 0 through the number of dimensions minus 1 inclusive. For example, an instance of a level 2 Animation (an Animation of Animations) has two levels: level 0 for the component Animations, and level 1 for the Animation of Animations.
At each of its levels, an AnimationInstance has an index of its current position in that level of the Animation, as well as a speed that represents how fast, in fracunits per GameState time unit, it advances through that level. Each level's index and speed are both initially 0. If a level's speed is negative, the AnimationInstance will cycle through the Animation at that level backward. If an AnimationInstance moves forward past a level's end or backward past its beginning, it will loop back to the beginning or end, respectively.
When an AnimationInstance is drawn, it will appear as the Sprite in its Animation that its current indices specify. The Filters that can be successfully applied to that Sprite when it is drawn through the AnimationInstance are the same ones as when the Sprite is drawn by itself.
AnimationInstances keep track of time by being assigned to one GameState each. An AnimationInstance's time factor represents the average number of discrete time units the AnimationInstance will experience every frame while assigned to an active GameState. If its own time factor is negative, as it is by default, an AnimationInstance will use its assigned GameState's time factor instead. If an AnimationInstance is assigned to an inactive GameState or none at all, time will not pass for it. AnimationInstances assigned to the active GameState update their indices at the beginning of each frame, before Thinkers' timer values are updated.
All operations on an AnimationInstance return the AnimationInstance itself to allow operations to be easily strung together.
