Fixed camera width?

Hello,

I'm making a game for android/ios and i want the width to be the same on all phones. I'm using an orthographic camera and here is an image illustrating what i want to do (the black bars are walls and the red squares are the visible area):

 

Anyone? I have googled for hours now and i can't come up with a solution. There must be way to do this, right? All i want to do is to make it show less/more on the height instead of the width.

EDIT: Solved it myself

 

Code (csharp):

1.  
2. Camera.main.aspect = width / Screen.height;
3.  

Aspect is basically the aspect ratio of the view area which is the width divided by the height.

 

Can you please show how you solved this? As I now face the same problem with the camera width while working on my game for Android/iOS.

 

Set the game to a resolution you want the game to look ideal in (for example 480x800) and then zoom the camera so it shows what you want it to show. Now, take ortographicSize/(SceenHeight/ScreenWidth). This will be your constant.

Then, simply use this code to set the size:

Code (csharp):

1.  
2. double size = yourConstant*(camera.GetScreenHeight()/camera.GetScreenWidth());
3.  

 

Oh thanks so much! I think I got it now. As in my case I want to set the game to 720x480, so I did it like this:

Code (csharp):

1. Screen.SetResolution(720,480,false);
2. float screenRatio = camera.orthographicSize/(480f/720f);
3. camera.orthographicSize = screenRatio*(camera.GetScreenHeight()/camera.GetScreenWidth());

Am I missing something here? (Didn't test this yet on different devices tho)

 

screenRatio should be a constant so you need to replace camera.orthographicSize with the size of the camera when it fits the way you want it.

 

Haha just take a look at my code today and realize I've made this line useless:

Code (csharp):

1. camera.orthographicSize = screenRatio*(camera.GetScreenHeight()/camera.GetScreenWidth());

Since nothing can change if I calculate "screenRatio" using "camera.orthographicSize". My bad Will need to take some Maths classes. Thanks again for figuring it out.
Cheers!
