The Y coordinate of the rectangle.
This value is the same as yMin, but setting it will move the
rectangle rather than resize it.
using UnityEngine;public class RectExample : MonoBehaviour
Rect rect = new Rect(10, 10, 50, 30);
// prints: y = 10
Debug.Log("y = " + rect.y); rect.y = 20;
// prints: (x:10, y:20, width:50, height:30)
