Должно ли быть применено корневое движение (root motion)?
Root motion is the effect where an object's entire mesh moves away from its starting point but that motion is created by the animation itself rather than by changing the Transform position. Note that applyRootMotion has no effect when the script implements a MonoBehaviour.OnAnimatorMove function.
Changing the value of applyRootMotion at runtime will re-initialize the animator.
