示例1: VUpdate

/*
All of this code must go!!! This is shit! Rewrite animation system as a seperate component, starting with a virtual base
class (AnimationComponent) that can then fork off into a bunch of other more specific animation types (e.g. HumanoidAnimationComponent,
MachineAnimationComponent, ParticleAnimationComponent, etc.).
*/
