How can i reverse all the booleans in a method?

Question

ok im not really sure how to ask this but maybe someone can help.

I would like to reduce one of these blocks of code ..

   void NotPressed ()
     {
         for (int i = 0; i < DangerousObjects.Count; i++)
         {
             isGroundButtonPressed = false;
             DangerousObjects[i].SetActive(true);
             animator.SetBool("GroundButtonOn", false);
         }
     }
     void Pressed()
     {       
         for (int i = 0; i < DangerousObjects.Count; i++)
         {
             isGroundButtonPressed = true;
             DangerousObjects[i].SetActive(false);
             animator.SetBool("GroundButtonOn", true);         
         }     
     }

so it can be something like this

   void NotPressed ()
     {
         !Pressed();
     }
     void Pressed(bool isPressed)
     {       
         for (int i = 0; i < DangerousObjects.Count; i++)
         {
             isGroundButtonPressed = true;
             DangerousObjects[i].SetActive(false);
             animator.SetBool("GroundButtonOn", true);         
         }     
     }

that doesnt work^ but im looking to do something like that.i dont need to do this -- i just want to know how someone one would go about doing that? is there a way i can flip all the boolean values to it's opposite value?

Hi @spencerz , I think you can try this

  void NotPressed ()
      {
         SetProperty(false)
      }
      void Pressed()
      {       
         SetProperty(true);
      }  
 
  void SetProperty (bool value)
      {
          for (int i = 0; i < DangerousObjects.Count; i++)
          {
              isGroundButtonPressed = value;
              DangerousObjects[i].SetActive(!value);
              animator.SetBool("GroundButtonOn", value);
          }
      }

Note that the SetProperty method can be simplified to

 void SetProperty (bool value)
 {
     isGroundButtonPressed = value;
     animator.SetBool("GroundButtonOn", value);
     for (int i = 0; i < DangerousObjects.Count; i++)
     {
         DangerousObjects[i].SetActive(!value);
     }
 }

There's simply no point in calling animator.SetBool multiple times. Likewise setting "isGroundButtonPressed" more than once is pointless.

To invert a bool you can use the ! operator so

 MyVariable = !MyVariable

Will flip it from what ever value it was to the alternative value.
