RectTransform.anchoredPosition

Description

The position of the pivot of this RectTransform relative to the anchor reference point.

The Anchored Position is the position of the pivot of the RectTransform taking into consideration the anchor reference point. The anchor reference point is the position of the anchors. If the anchors are not together, Unity estimates the four anchor positions using the pivot placement as a reference.

        m_RectTransform = GetComponent<RectTransform>();
        //Initiate the x and y positions
        m_XAxis = 0.5f;
        m_YAxis = 0.5f;
