Keeping screen width and scaling screen height for different screen resolutions

Question

Hi guys,

I need my game to have a constant screen width for every mobile device in the market. For this I need to scale the screen height in order to keep the same screen width, even though the screen ratio varies.

Here you have an example:

alt text

You see the width is the same for both resolutions and only the screen height varies.

Any idea of how I can do this?

Thanks in advance!

EDIT:

Found this: http://gamedesigntheory.blogspot.ie/2010/09/controlling-aspect-ratio-in-unity.html

Is there a way to edit it to scale height instead of adding black frames? (keeping the width)

Up!

You need to change your camera orotographics size following the next formula:

 ortographicSize = constantWidth / aspectratio * 2f;

Sorry, maybe the screenshots weren't much accurate. My camera is 3D.

try using Screen.SetResolution as seen in the documentation

     function Start()
     {
         var resolutions : Resolution[] = Screen.resolutions;
         // Print the resolutions
         for (var res in resolutions) {
             print(res.width + "x" + res.height);
         }
         // Switch to the lowest supported fullscreen resolution
         Screen.SetResolution (resolutions[0].width, resolutions[0].height, true);
     };

try this:

     var verticalFOV : float =60;
     var forcedAspectRatio: float = 0.75;
     var manualNearClipPlane : float = 0.01;
     var manualFarClipPlane : float = 1000;
      
     function Update(){
         camera.projectionMatrix = Matrix4x4.Perspective(verticalFOV, forcedAspectRatio, manualNearClipPlane, manualFarClipPlane);
     }
