    After I've finished my first bigger project (Bounce Line) I've noticed that I've could optimize the game much better, make it work on different resolutions without graphical glitches ... etc. Also I've noticed that it had some lag on mobile browsers, so I've begun to test what mobile browsers can handle.

    In the meantime time I've changed my personal phone from LG Optimus 2X (Android 4.0.4) to Nokia Lumia 925 (Windows Phone 8). While testing the C2 accelerometer functions on mobile browser I've observed that it doesn't work on Windows Phone 8 at all.

    This is the test page: http://tinyurl.com/c2acceltest

    Here is the CAPX file: BrowserAccelTest.capx

    I've invested some free time to get the following results:

    My conclusions:

    1.

    You could say that

    (�_�)

    ( �_�)>��-�

    (��_�)

    WindowsPhone can't handle dancing Megaman

    YEEEEAAAAAAAAHH <img src="smileys/smiley16.gif" border="0" align="middle">

    2. Browser.BatteryLevel is supported only by a few browsers (all of them on Android only). This function would be usefull for FullScreen games in order to see the battery level during gameplay until is too late (when you receive the low battery warning)

    3. Touch.Acceleration_, Touch.Acceleration_WithG, Alpha, Beta, Gamma returns the same values regardless the orientation ... So you would have to make 4 different profiles for it (Portrait, Upside Down, Landscape Left, Landscape Right)

  • It's the browser that doesn't support those features. C2 can use them if the browser supports them, but if the browser doesn't then there's not much that can be done. Hopefully the Windows Phone 8.1 update with IE11 will fix a lot of that.

  • I thought it had something to do with the manifest file <img src="smileys/smiley24.gif" border="0" align="middle" />

    Thanks for the answer

  • Try Construct 3

  • Is there a way to hard code in a C# method to give a value from acceleometer to the c2runtime? More explanation from me in this thread:

    As far as I'm concerned, at the moment it works on Android and iOS ... And WindowsPhone 8.1 update will bring Internet Explorer Mobile 11 <img src="smileys/smiley2.gif" border="0" align="middle" />

    When I get my hands on the 8.1 SDK soon, I'll let you know.

  • This can be done with C#, and in truth it has been on my backlog for a long time. Windows Phone 8.1 should support it though, so I'll wait and see before adding anything.

  • I have tested the browswer test from IE (windows phone) and it works (more less) but after exporting the same project to Windows Phone and running it in the device, cant' get the alfa,beta, gamma values.

    Is this a bug ? Shouldn work ? since it works from the browser...

    Does someone knows if it's possible to get alfa, beta, gamma values from the acceloremeter when exportin to WP8 ?

    Thanks in advance
