QualitySettings.antiAliasing = 0; not working

I am having a problem with a toggle function in a settings menu. The toggle recognises and reacts when it is enabled however when you disable it, it doesn't recognise that it is off or react to it. I have been having problems for days and it is starting to get on my nerves. Here is the code:

Code (csharp):

1.  
2. public Canvas options_nav;
3.     public Canvas graphics_menu;
4.     public Toggle option_antialiasing;
5.     public Button exit;
6.  
7.     void Start()
8.     {
9.         options_nav = options_nav.GetComponent<Canvas>();
10.         graphics_menu = graphics_menu.GetComponent<Canvas>();
11.         option_antialiasing = option_antialiasing.GetComponent<Toggle>();
12.         exit = exit.GetComponent<Button>();
13.         options_nav.enabled = false;
14.     }
15.  
16.     public void optionantialiasing()
17.     {
18.         if(option_antialiasing == false)
19.         {
20.             QualitySettings.antiAliasing = 0;
21.         }
22.         else
23.         {
24.             QualitySettings.antiAliasing = 4;
25.         }
26.     }
27.  

The else statement works fine and turns on Anti-Aliasing however the if statememnt doesn't I have set unity to have anti-aliasing set to 0 by default and the toggle is set to off by default so it must be in the code or a bug with Unity.

 

You are checking for the toggle, not for its state.

if(option_antialiasing.isOn == false)...

 

it should be like:

Code (csharp):

1. if(QualitySettings.antiAliasing != 0)
2. {
3.     QualitySettings.antiAliasing = 0;
4. }
5. else
6. {
7.     QualitySettings.antiAliasing = 4;
8. }

instead

It's wrong to evaluate if class is true or false.

 

Thank you so much. That has been annoying me for ages and in a game as big as this with only 2 people building it we are really struggling Thank you so much!

 

Also, if you want to set it according to your toggle state then it should be like Carpe Denius said.
