Setting up Axios Engine

Content

You will need to add the "shared content" available here: http://code.google.com/p/axiosengine/downloads/detail?name=Content.zip&can=2&q= This includes shared content with Farseer and other free textures.

As simplistic as I wanted this engine you still need to add a few lines to your game.

Game class

Add this property:

public ScreenManager ScreenManager { get; set; }

Constructor

Add the following lines:

#if WINDOWS || XBOX360
            Settings.SetResolution(graphics, ResolutionSetting.Windows);
#elif WINDOWS_PHONE
            Settings.SetResolution(graphics, ResolutionSetting.WP7_Landscape);
#endif
            ConvertUnits.SetDisplayUnitToSimUnitRatio(Axios.Settings.DisplayUnitToSimUnitRatio);
            ScreenManager = new ScreenManager(this);
            Components.Add(ScreenManager);

Initialize

Add your screens in this method

ScreenManager.AddScreen(new UIScreen1());

References

And of course you need to reference Axios.{os}.dll in your project if you don't include the source code for Axios in your project.

Sample

    public class Game1 : Microsoft.Xna.Framework.Game
    {
        GraphicsDeviceManager graphics;
        SpriteBatch spriteBatch;

        public ScreenManager ScreenManager { get; set; }

        public Game1()
        {
            graphics = new GraphicsDeviceManager(this);
            Content.RootDirectory = "Content";

            graphics.IsFullScreen = false;
#if WINDOWS || XBOX360
            Settings.SetResolution(graphics, ResolutionSetting.Windows);
#elif WINDOWS_PHONE
            Settings.SetResolution(graphics, ResolutionSetting.WP7_Landscape);
#endif
            ConvertUnits.SetDisplayUnitToSimUnitRatio(Axios.Settings.DisplayUnitToSimUnitRatio);
            ScreenManager = new ScreenManager(this);
            Components.Add(ScreenManager);
        }
