    text
    copied!<p>Would it be possible to open a custom screen or a popup(modal) in an XNA Game.The idea is to display a few options to the user w.r.t the game and other apps that will be a part of the app suite.</p> <pre><code>public class MyGame : Game { #region Initialization /// &lt;summary&gt; /// Creates a new instance of the game. /// &lt;/summary&gt; public MyGame() { graphics = new GraphicsDeviceManager(this); Content.RootDirectory = "Content"; ///etc; } /// &lt;summary&gt; /// Performs initializations required by the game. /// &lt;/summary&gt; protected override void Initialize() { ///I would Like to open a new screen before the actual game /// menu is displayed ... also return to this screen after the logic is run /// in that screen base.Initialize(); } } </code></pre> <p>Any Ideas/Suggestions/Samples . Thanks in Adv.</p> <p>Krz.</p> <hr> <p>Thanks Blau.I tried the DrawableGameComponent solution(copied the code from an article) but in vain.No matter what I do ,just a blank screen is displayed.</p> <p>In the Game Constructor I put a condition and call the method as </p> <pre><code>if (showScreen) { LaunchScreen launcher = new LaunchScreen(this, null); //Components.Add(launcher); launcher.Show(); } else{///constructor code} </code></pre> <p>I also put a condition in the Game Initialize so that if showScreen is flase then execute.(Not sure if its a proper way to do)</p> <p>The Class looks like this :</p> <pre><code>public class LaunchScreen : DrawableGameComponent { private Texture2D backgroundImage = null; private SpriteBatch spriteBatch = null; public LaunchScreen(Game game, Texture2D texture) : base(game) { backgroundImage = texture; Visible = false; Enabled = false; } public virtual void Show() { Visible = true; Enabled = true; } public virtual void Hide() { Visible = false; Enabled = false; } public override void Initialize() { base.Initialize(); } public override void Update(GameTime gameTime) { base.Update(gameTime); } public override void Draw(GameTime gameTime) { //if (backgroundImage != null) //{ spriteBatch = new SpriteBatch(base.GraphicsDevice); if (Game.Services.GetService(typeof(SpriteBatch)) == null) Game.Services.AddService(typeof(SpriteBatch), spriteBatch); Rectangle screen = new Rectangle(0, 0, Game.Window.ClientBounds.Width, Game.Window.ClientBounds.Height); Texture2D lauT2D = this.Game.Content.Load&lt;Texture2D&gt;("Textures/BG"); spriteBatch.Draw(lauT2D, screen, Color.White); //} ///SpriteFont font = this.Game.Content.Load&lt;SpriteFont&gt;("Fonts/MenuFont"); ///Vector2 spritePosition = Vector2.One; ///spriteBatch.DrawString(font, "Goodness ME", spritePosition, Color.White); base.Draw(gameTime); } } </code></pre> <p>I am totally confused on how to initialize the GraphicDevice and the SpriteBatch and open the window before the actual game runs/initializes.
