Like I mentioned before, the upside of switching all animation in the game to be procedural (simulated) instead of keyframe-animated is that you get fun stuff like jiggling and whiplashing for free.. the downside is that you’re now essentially dealing with a robot in a simulated physical world, so you have to teach it to move itself around the same as you would with a robot in the real world: using joints and motors and this and that…which is fun but challenging.  Here you can see poor Spaz with his new motorized legs not doing a very good job at walking just yet.
