public Vector3 localPosition ;

説明

Position of the transform relative to the parent transform.

If the transform has no parent, it is the same as Transform.position.

Note that the parent transform's world rotation and scale are applied to the local position when calculating the world position. This means that while 1 unit in Transform.position is always 1 unit, 1 unit in Transform.localPosition will get scaled by the scale of all ancestors.
