    using System;
    using System.Collections.Generic;
    using System.Linq;
    using System.Net;
    using System.Windows;
    using System.Windows.Controls;
    using System.Windows.Media;
    using System.Windows.Navigation;
    using Microsoft.Phone.Controls;
    using Microsoft.Phone.Shell;
    using PhoneApp1.Resources;

    namespace PhoneApp1
        public partial class MainPage : PhoneApplicationPage
            // Constructor
            public MainPage()
                CompositionTarget.Rendering += new EventHandler(this.CompositionTarget_Rendering);


            private void CompositionTarget_Rendering(object sender, EventArgs e)
                int counter=0;
                var frame_num=0;
                int xOffset;
                int yOffset;

                if (counter > 500)
                    counter = 0;

                if (counter % 15 == 0)
                        if (frame_num <= 2)
                            frame_num = 0;

                   RectangleGeometry r = new RectangleGeometry();
                    xOffset = (frame_num) * 100;
                    yOffset = 0;// (frame_num / 5) * 168;
                    r.Rect = new Rect(xOffset, yOffset, 61, 168);
                    spr.Clip = r;

                        //We have to compensate for the clipping region offset so the sprite stays in place.
                  //  transpos.X = -xOffset; transpos.Y = -yOffset;


    <Grid x:Name="LayoutRoot">

            <Image x:Name="spr" Source="Assets/Aarro Sprite.png" Stretch="None" Margin="10,195,68,303">


                     <TranslateTransform x:Name="transpos" X="61" Y="119" />

  • Are you trying to write a Windows Store app or a Windows Phone app?

    The Windows Store apps forums are specific to Windows Store apps, but the code you list is specific to Windows Phone and isn't expected to work in a Windows Store app.

  • Its for windows store, but i'm just learning to implement it on windows phone. i thought i could use similar method for windows store later. Would the code be so different?, Thanks for any feedback you might have in this matter.
