public Vector3 localPosition ;


Position of the transform relative to the parent transform.

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

    // Move the object to the same position as the parent:
    transform.localPosition = Vector3(0, 0, 0);

// Get the y component of the position relative to the parent // and print it to the Console print(transform.localPosition.y);

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.
