Creating a game sprite: Simple keyframe animation

In this section we look at how to do key framed animation.  What exactly is keyframe animation?  In simple terms, you define a few (*cough* key *cough*) frames of animation ( by posing or positioning your model ) and then the computer fills in the missing animation.  It’s exceedingly handy as it greatly simplifies the animation process ( it would really suck if you had to update every single movement on every single frame! ) and it also reduces the amount of data you need to store.  Fortunately, except for a few gotchas, keyframe animation is pretty simple in Blender.
