Animation Bootcamp: An Indie Approach to Procedural Animation

> [this video] David Rosen pulled off quite a few little masterpieces -- his gamedev competition entries always had fantastically unique aspects. I cannot believe "Black Shades" was almost 20 years ago! (I have no affiliation, but I am glad to see [link] is still alive and kicking!) Lugaru and later Overgrowth have been the outcomes of what can only be called a decades long obsession with getting the player controls just right, allowing very natural and responsive control and movement, through creating emergent behaviors from first principles, resulting in a rich and natural interaction with the environment (and other characters, see the fighting mojo), in contrast to the many, many AAA titles that just constantly break the immersion through unnatural, jarring behaviors and frustrating limitations.

Not the person you asked, but here's a video you might like: [this video] In that example, they do the character's physics first (just a ball), then match the animation to it. The animation speed is controlled by a "surveyor wheel" approach — go to to 336s in the video for that part. So, the animation speed is derived from the physics, rather than the physics speed being derived from the animation. I wouldn't call that "IK" exactly, which would be more for things like matching the foot to individual stair steps as the character walks up them, or such. But I suppose in a broader sense it is, since you're deciding on a physical goal a-priori, then forcing the animation to match that goal.
