Do Something ONLY when all Toggles are On or Off

Yes. Use an if statement. I used int instead of bools. Seemed easier.

  using UnityEngine;
  using System.Collections;
  
  public class ToggleTest : MonoBehaviour {
  
      public int sw1 = 0;
      public int sw2 = 0;
      public int sw3 = 0;
      public bool indicator = false;
      public int lastCount = 0;
      public int count = 0;
      
      // Update is called once per frame
      void Update () {
      
          if(lastCount == 3 && count == 2 && indicator == true)
          {
              indicator = false;
          }
          else
          {
              if(count == 3)
              {
                  indicator = true;
                  lastCount = count;
              }
              else if(count > 0 && lastCount != 3)
              {
                  lastCount = count;    
              
                  
                  indicator = true;
              }
              else if(count == 0)
              {
                  indicator = false;
                  lastCount = count;
              }
  
              count = sw1 + sw2 + sw3;
          }
      }
  }

Use &&, t$$anonymous$$s is boolean function that returns true if all inputs are true.

Wow Thanks @meat5000, @ItsIcear, & @saschandroid, I was searc$$anonymous$$ng all over the place for a way to do t$$anonymous$$s, t$$anonymous$$s gives me a lot to try out, I'll see what I come up with today and report back the results.

But just to re cap a little the indicator toggle is just to signal that any of the toggle buttons are ON, That way it means the device is active in some function, by either one or all of the 3 toggle buttons.

BUT if ONLY say one of the toggles is off and the other two are ON then the indicator toggle would need to be ON because it would mean the device is active in some way governed by the 2 toggle being ON.

Now if all toggle are OFF the the device is NOT active in any way so the "Indicator" toggle would then be off.

In my attachment you can see at the top I have an indicator that says Activate/Deactivate and on the bottom I have 3 buttons for "Audio" "Video" and "Heat Sensor" It is these 3 buttons that govern the top indicator being on..... I t$$anonymous$$nk you guys are on the right track with what I'm trying to do though ;) I'll see what I come up with ;)
