JavaScript Level Loading Disable A Layer

Hi guys, i've got a level loading script, this goes from main menu to a loading screen to the level. The only problem is when it's showing the loading screen, it disables the 3D text, but the map is still there. How would i make it so that when the loading screen is displayed, it disables the gameobject (the map).

Here's my code:

 var levelToLoad : String;
 var soundhover : AudioClip;
 var beep : AudioClip;
 var QuitButton : boolean = false;
 var loadScreenObject : GameObject;
 
 function OnMouseEnter(){
 audio.PlayOneShot(soundhover);
 }
 function OnMouseUp(){
 audio.PlayOneShot(beep);
 yield new WaitForSeconds(0.35);
 if(QuitButton){
 Application.Quit();
   var gos : GameObject[] = GameObject.FindObjectsOfType(typeof(GameObject));
     for( var go : GameObject in gos) {
        if (go.renderer) {
          go.renderer.enabled = false;
        }
     }
 }else
 {
     if (loadScreenObject != null) {
         loadScreenObject.SetActiveRecursively(true);
     }
     //yield WaitForSeconds(3);
     yield WaitForEndOfFrame();
     Application.LoadLevel(levelToLoad);
     //AsyncOperation async = Application.LoadLevelAsync(levelToLoad);
     //yield async;
     yield 0;
 
     
     
 }
 }
