Unity3D: Moving GameObjects with mouse and check contains

Question

How can I move an object (a gameobject fill color using GUITexture for example) by mouse click/touch to grid and check contains fill color for each tile?

If use Camera.main.ScreenToWorldPoint then can't check contains. Current my code to check contains work fine but gameobject not move with mouse :(

My code is follow:

void OnMouseDown()
    {
        Vector2 mousePos = new Vector2(Input.mousePosition.x, Screen.height - Input.mousePosition.y);
        transform.position = mousePos;
        Debug.Log("OnMouseDown: transform.position: " + transform.position);
    }
    void OnMouseDrag()
    {
        Vector2 mousePos = new Vector2(Input.mousePosition.x, Screen.height - Input.mousePosition.y);
 
        transform.position = mousePos;
        Debug.Log("transform.position: " + transform.position);
 
        foreach (var x in GameBoard.Instance.listTileInGrid)
        {
            if (x.RectTile.Contains(mousePos))
            {
                Debug.Log("change color");
                x.ColorId = 1;
            }
        }
    }

Thanks in advance!

update:

i change:

transform.position = mousePos;

to

transform.guiTexture.transform.position = Camera.main.ScreenToViewportPoint(Input.mousePosition);

This is pretty simple. You can use the Vector3.Lerp function to achieve this. Use raycasting to get the mouse click position or the touch position. Then use the initial and the final position in the lerp function. The initial position being the position that the gameobject is at now and the final position being the click / touch position. You can find the article by The Game Contriver on the same here
