Rect.x

public float x;

Описание

Верхний левый угол (координаты точки) прямоугольника

This value is the same as xMin, but setting it will move the rectangle rather than resize it.

using UnityEngine;

public class RectExample : MonoBehaviour
{
    // Use this for initialization
    void Start()
    {
        Rect rect = new Rect(10, 10, 50, 30);
        Debug.Log("x = " + rect.x); // -- prints: x = 10
        rect.x = 20; 
        Debug.Log(rect); // prints: (x:20, y:10, width:50, height:30)
    }
}
