Draw crosshair INSTEAD of cursor.

This is for the non hardware accelerated crosshair.

It will simply place the UI texture on the center off the mouse pointer. note that the clicking happens on the left corner of the pointer, so you have to tweak the adjust paramters to center your texture on the left corner of the pointer. With an extra script you can switch out the texture with different ones (not included in this script). that way you can created item icon's and so on.

     using UnityEngine;
     using System.Collections;
     
     
     public class crosshair : $$anonymous$$onoBehaviour {
         static public bool center =true;
       static  public bool cursorOff =false;
         
         
         public float cursorAdjustY;
         public float cursorAdjustX;
         public Texture crosshairTexture;
         public int W;
         public int H;
         public bool on=true;
         
         void OnGUI(){
             if(on==true){
             GUI.DrawTexture(new Rect(Screen.width/2+cursorAdjustX, Screen.height/2+cursorAdjustY, W, H), crosshairTexture, Scale$$anonymous$$ode.ScaleToFit);
         
             }
         }
                 
 // Update is called once per frame, this will hide your      //original mouse, but still keep its functions. On low fps
 //this will cause mouse flicker.
         void Update () {
           Screen.lockCursor = cursorOff;
          Screen.lockCursor = center;
         }
     }
