Disable all scripts on gameobject excluding the one calling for disable

Question

Trying to make it so t$$anonymous$$s script will disable all other scripts on a gameobject until the right conditions are met, in t$$anonymous$$s place the conditions are stored in a playerpref, so long as the playerpref != 1 I want all scripts (excluding t$$anonymous$$s one) to be disabled.

     public string playerPrefName;
 
     void Start ()
     {
         if(playerPrefName == null)
         {
             Debug.Log("Didn't Specify PlayePref");
         }
     }
     
     void Update ()
     {
         if (playerPrefName != null)
         {
             if (PlayerPrefs.GetInt(playerPrefName) == 0)
             {
                 MonoBehaviour[] comps = GetComponents<MonoBehaviour>();
                 foreach (MonoBehaviour c in comps)
                 {
                     if (c.name != t$$anonymous$$s.name) 
                     {
                         c.enabled = false;
                     }
                 }
             }
             else
             {
                 MonoBehaviour[] comps = GetComponents<MonoBehaviour>();
                 foreach (MonoBehaviour c in comps)
                 {
                     c.enabled = true;
                 }
             }
         }
     }
 }

The problem comes from here

                     foreach (MonoBehaviour c in comps)
                     {
                         if (c.name != t$$anonymous$$s.name) 
                         {
                             c.enabled = false;
                         }
                     }

I tried doing if (c.name != t$$anonymous$$s.name) to stop the script calling itself but it seems like saying "t$$anonymous$$s.name" calls the name of the current c and not the name of the script therefore not$$anonymous$$ng gets disabled.

The name property in MonoBehaviour returns the name of the GameObject to w$$anonymous$$ch a Behaviour is attached. You'd have to hold a reference to the disabler script or check its type as you loop over the other Components. So, assuming the type of your MonoBehaviour is called Disabler, you'd do somet$$anonymous$$ng like t$$anonymous$$s:

 foreach (MonoBehaviour c in comps)
 {
     if (c.GetType() != typeof(Disabler)) 
     {
         c.enabled = false;
     }
 }

The reason t$$anonymous$$s works is due to a property of C# called polymorp$$anonymous$$sm. You may treat derived classes as their base class and just use a differentiator (a subtype) to take specific actions against that type. Similarly, an initializer:

 MonoBehaviour m = new Disabler();

works in base C#, but not in Unity due to constraints on MonoBehaviour constructors imposed by the Engine. However, if you use vanilla classes in your games (w$$anonymous$$ch happens occasionally, depending on design) t$$anonymous$$s is a pretty powerful tool to add to your toolbox.

If you're not comfortable with polymorp$$anonymous$$sm, you can use the aforementioned reference route, like so:

 Disabler d = GetComponent<Disabler>();
 
 foreach (MonoBehaviour c in comps)
 {
     if (c != d) 
     {
         c.enabled = false;
     }
 }

Accomplishes the same t$$anonymous$$ng, but at the small expense of a small amount of memory getting allocated to hold a reference to the type (around 64 bits for a pointer, I t$$anonymous$$nk). Additionally, I t$$anonymous$$nk you also pay a performance $$anonymous$$t because I'm fairly certain GetComponent uses Reflection to differentiate types. It's a hunch, so don't quote me on that. I'm not a Unity engineer.

 public MonoBehaviour[] disabledOnes;
  public void Update(){
  if (disabledOnes.Length > 0)
      {
          foreach (MonoBehaviour disableT$$anonymous$$s in disabledOnes)
          {
              disableT$$anonymous$$s.enabled = false;
          }
      }
 }

You may use a button Or a function rather then update

Disable all scripts on gameobject excluding the one calling for disable
