Description

Unity Animation And Physics Binding - is attempt to make simple tool for blending animations with physic. It is not production ready, it is prototyte, that can be used as start of your realisation.

Made with Unity 2020.1

How to use

• You should create two game objects: one for reference animation (for example using Animator Controller, or script), second for physic (for example with rigidbody)
• Add script AnimationBlender to any root bone you want to animate. AnimationBlender will apply animation from reference animation object to this object and all his children.
• Setup all parameters
  • Reference - object for taking animation
  • Check Bones Names - Should we fail if bones name are not equal
  • Animation Factor - How much animation updates should be applied
  • Resolve Factor - How much physic body should try to return to animation angles (bigger values - closer to animation, but bigger jitter with physic)
  • Ingore - A list of Transforms to ignore (animation will not be applied)

What sholud be enhanced

• To make character stay in the place you need to ignore one bone, for example, hip and make its rigidboby Kinematic. It will allow the animation
• Joints should be set up depends on your animation. Movement of your animations will be not so intensive if it is not allowed by joints
• Physic will affect the doll, even if you will set all parameters to the maximum. So you will never have animations that look 100% as original
• Algorithm depends on bones' game objects transforms order, names, and hierarchy. It will not work if it is not equals
