rotationFrom

The start rotation of the tween. When the PhysicsBody.TransformWriteTween.transformWriteMode is PhysicsBody.TransformWriteMode.Current, this is set to the last Transform.rotation but is not used. When the PhysicsBody.TransformWriteTween.transformWriteMode is PhysicsBody.TransformWriteMode.Interpolate, this is set to the last Transform.rotation. When the PhysicsBody.TransformWriteTween.transformWriteMode is PhysicsBody.TransformWriteMode.Extrapolate, this will be calculated from PhysicsBody.TransformWriteTween.physicsTransform. See Transform.rotation.
