Change arrow mouse to texture

Create Script “MouseCursor” to change the texture of the mouse in C# (CSharpe) or js (JavaScript)

For c# :

using UnityEngine;  
 using System.Collections;  
 public class MouseCursor : MonoBehaviour {  
         public Texture2D crosshairTexture;  
         public Rect position;  
         void Start()  
                 {  
                 Screen.showCursor = false;         
                 position = Rect( ( Screen.width - crosshairTexture.width ) * 0.5f, ( Screen.height - crosshairTexture.height ) * 0.5f, crosshairTexture.width, crosshairTexture.height );  
                 }  
         void OnGUI()  
                 {  
                   GUI.DrawTexture(position, crosshairTexture);   
                 }  
 }  

For c# :

var crosshairTexture : Texture2D;  
 var position : Rect;  
 function Start()  
                 {  
                 Screen.showCursor = false;         
                 position = Rect( ( Screen.width - crosshairTexture.width ) * 0.5, ( Screen.height - crosshairTexture.height ) * 0.5, crosshairTexture.width, crosshairTexture.height );  
                 }  
 function OnGUI()  
                 {  
         GUI.DrawTexture(position, crosshairTexture);  
                 }
