Screen resolution not changing?

Code (csharp):

1.  
2. var ScreenResolution : int = Screen.width/Screen.height;
3.  
4. function Start ()
5. {
6.     // set screen resolution width/height = 1.6 widescreen 16:10 or 1.33 normal 16:9
7.     if (Screen.width < 1024) {
8.         Application.Quit ();
9.         }
10.     else if (ScreenResolution == 1.6) {
11.         Screen.SetResolution (1280, 800, true);
12.         }
13.     else {
14.         Screen.SetResolution (1024, 768, true);
15.         }
16. }
17.  

Any clue why this doesn't work? At least it doesn't give me an error -- which is what my coding normally produces -- but test screen shots (when I simply set one or the other resolution manually) show only 1024 resolution.

 

The main problem is that you're defining ScreenResolution as an integer, so it's always going to be 1 (unless you have a really wide screen, like 2:1). The other problem is that Screen.width and .height always return integers, so even if you define screenResolution as a float, it will still only be 1. At least one of the values has to be a float in the first place in order to get a float as a result.

Code (csharp):

1.  
2. var screenWidth : float = Screen.width;
3. var screenResolution : float = screenWidth / Screen.height;
4.  

Is there any way to force Screen.width height to calculate as floats in Javascript? In C# you could do "float screenResolution = (float)Screen.width / (float)Screen.height", thus saving a line of code...OK, so C# isn't all bad after all....

Another problem is that you don't wanna do stuff like "else if (ScreenResolution == 1.6)" because getting precise numbers out of floats is iffy. You might end up with 1.6000000001 or something because of floating point errors. You want to compare a range instead. (Like greater than 1.5 and less than 1.7.)

Code (csharp):

1. (0.0+Screen.width) / Screen.height

Clunky, but should work...

Btw. the result of the division is stored in a variable called "screenResolution". Shouldn't that be "screenRatio" instead?

 

Thanks to both. I will tackle tonight (full time works get in the way of so much, doesn't it?)
