auto scaling in monogame for windows store games using xna and xaml

Question

Is there any best way to do auto scaling for windows store games developed in monogame,I am facing many problems ,Currently i am doing this. following is two lines of code which is useful for keeping my games windows to fixed scale.

 graphics.PreferredBackBufferHeight = 768;
  graphics.PreferredBackBufferWidth = 1024;

but this is solving my problem.

Answer 1

see bleow code for autoscaling for your store game two vars scalesx and scaley , divide the current deveice width and height by your required resolution i am taking 1024 and 768 because in pc's this smallest resolution those which will run windows 8 OS. when you pass x and y co-ordinates for rectangles and vectors multiply it scalex and scaley and the pos according to 1024*768 resolution

i have taken x of rect (int)(scalex*102) ------>by this, x of rect is at 102px but for autoscale multiply it by scalex.

  ` public static float scaley,scalex;
        scalex = (float)graphics.GraphicsDevice.Viewport.Width / 1024;
        scaley = (float)graphics.GraphicsDevice.Viewport.Height / 768;

   jumposition = new Rectangle((int)(scalex*102),(int)(scaley*320),(int)(scalex*250),(int)(scaley* 250));`
