ScreenCursor' code no longer working in 4.6.3

Hi,

I had some code to restrict cursor movement that worked well in a earlier version of unity, but trying to use it in 4.6.3 makes it throw up an error:

Assets/Level1_Scripts/Restric_Cursor.cs(9,25): error CS0103: The name `ScreenCursor' does not exist in the current context

Monodevelop doesn't like the line:

ScreenCursor.SimulateMove

I'm not sure what's going wrong because it used to work. Any feed back would be great!

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3.  
4. public class Restric_Cursor : MonoBehaviour {
5.     public Vector2 RectSize;
6.     public bool Visible;
7.     void Update () {
8.         if (!new Rect(Screen.width/2-RectSize.x/2,Screen.height/2-RectSize.y/2,RectSize.x,RectSize.y).Contains(Input.mousePosition)) {
9.             ScreenCursor.SimulateMove(new Vector2(Screen.width/2,Screen.height/2),0.2f,true);
10.         }
11.     }
12.     void OnGUI() {
13.         if (Visible) {
14.             GUI.Box(new Rect(Screen.width/2-RectSize.x/2,Screen.height/2-RectSize.y/2,RectSize.x,RectSize.y),"");
15.         }}
16. }

 

I think you have to declare what ScreenCursor is, like you did with Rectsize and Visible. (public Vector2 RectSize; )
