renderer.enabled question

Question

Why does this code work:

     function Start()
     {
         renderer.enabled = false;
     }
     function Update () 
     {
         if(Input.GetKeyUp("m"))
             renderer.enabled = true;
         if(Input.GetKeyUp("n"))
             renderer.enabled = false;
     }

But this code doesn't:

 function Start()
 {
     renderer.enabled = false;
 }
 
 function Update () 
 {
     if(Input.GetKeyUp("m"))
     {
         if(renderer.enabled == true)
         {
             renderer.enabled = false;
         }
         if(renderer.enabled == false)
         {
             renderer.enabled = true;
         }
     }

This one will render the object, but will not un-render it.

Because:

 if(renderer.enabled == true)
     {
         renderer.enabled = false;
     }

OK, so that sets renderer.enabled to false. And then:

 if(renderer.enabled == false)
     {
         renderer.enabled = true;
     }

renderer.enabled was false, so you just immediately set it back to true again. You should use else if, or better yet, just toggle it:

 if(Input.GetKeyUp("m"))
 {
     renderer.enabled = !renderer.enabled;
 }

The problem is that computers only do exactly what you tell them to do, not what you want them to do. ;)

Oh yeah, got a similar question. maybe it's that easy as above. With Cube = GameObject.Find("Cube"); defined within Start(). This code works pretty fine, but when i uncomment the "else" line, "D" doesn't have any effect anymore. WHY ???

 if(Input.GetKeyDown(KeyCode.D)){
                 
     if(Cube.renderer.enabled){
         Cube.renderer.enabled = false;
     }
     //else Cube.renderer.enabled = true;                        
 }
                     
 if(Input.GetKeyDown(KeyCode.V)){
     Cube.renderer.enabled = true;            
 }
             
 if(Input.GetKeyDown(KeyCode.F)){
    if(gameObject.renderer.enabled){
        gameObject.renderer.enabled = false;
    }
    else gameObject.renderer.enabled = true;            
 }
