Congratulations! You're now able to render fully animated 3D models! While this is a pretty cool achievement, the functionality we've seen so far has only scratched the surface of what the IwAnim API allows us to do. The following sections describe some of the other features that we have at our disposal.
There are some occasions when it is useful to be able to play an animation backwards. As an example, imagine a character kneeling down to examine an object. Rather than create a whole new animation to enable them to stand up again, we could just play the kneeling animation backwards instead.
Playing an animation backwards is achieved simply by passing a negative animation speed into the
call to PlayAnim, so a value of -1 will play the animation backwards at normal speed.
