use same button for cameraZoom?

Hi again!
I'm trying to use one button to change the camera zoom from 11 to 16 to 20...
So, each time I press the button I want it to jump from Zoom 11 -> 16 -> 20 (and back to 6) so its basically rotating...In my current script i've set 11f as "default" and I can change the cameraZoom by pressing 2 different buttons.. Any easy way to make a "rotating schedule" for the camera zoom?

Code (csharp):

1.  
2.     public float camSize = 11f;
3.  
4.     void Start()
5.  
6.     // Update is called once per frame
7.     void Update()
8.     {
9.         if (Input.GetKey(KeyCode.I))
10.         {
11.             camSize = 16f;
12.         }
13.         else if (Input.GetKey(KeyCode.O))
14.         {
15.             camSize = 20f;
16.         }
17.     }
18.  

Thanks in advnace!

 

For example something like this:

Code (CSharp):

1. if (Input.GetKey(KeyCode.R)
2. {
3.     if(camSize==6f)
4.     {
5.         camSize=11f;
6.     }
7.     else if(camSize==11f)
8.     {
9.         camSize=16f;
10.     }
11.     else if(camSize == 16f)
12.     {
13.         camSize=20f;
14.     }
15.     else if(camSize == 20f)
16.     {
17.         camSize=6f;
18.     }
19. }

 

Oh my god you made that looks so simple (Emoji slapping his face) - that worked perfectly Thanks alot!

 

You could also do something like:

Code (CSharp):

1. float[] _zoomLevels = new float[] { 6, 11, 16, 20 };
2. int _zoomIndex = 0;
3.  
4. if(Input.GetKey(KeyCodes.R)
5. {
6.     _zoomIndex++
7.     if(_zoomIndex >= _zoomLevels.Length)
8.         _zoomIndex = 0;
9.     camSize = _zoomLevels[_zoomIndex];
10. }

 

thnaks, that look even cleaner!
