Animator根骨骼运动原始实现代码

实测过确实可行，注意如果没有刚体组件，实现方式会不一样

public class TestSMB : StateMachineBehaviour

{

    public override void OnStateMove(Animator animator, AnimatorStateInfo stateInfo, int layerIndex)

    {

        Vector3 velocity = animator.deltaPosition / Time.deltaTime;

        var rigidbody = animator.GetComponent<Rigidbody>();

        if (rigidbody != null)

        {

            velocity.y = rigidbody.velocity.y;

            rigidbody.velocity = velocity;

        }

    }

}
