> The start position of the tween. When the _transformWriteMode is PhysicsBody.TransformWriteMode.Current, this is set to the last _position. but is not used. When the _transformWriteMode is PhysicsBody.TransformWriteMode.Interpolate, this is set to the last _position. When the _transformWriteMode is PhysicsBody.TransformWriteMode.Extrapolate, this will be calculated from _physicsTransform. See _position.
