Question

我在XNA项目中加载了一段视频，然后我开始玩了。唯一的问题是它垂直切成两半。视频大小为800x600，游戏也是800x600。起初我意外地在我的内容中放置了640x480版本的视频，但后来我将其修复为800x600。虽然没有修正1/2垂直。我想也许640x480 xnb仍然在那里并且正在加载。我试着寻找它并删除了我认为相关的任何内容，但这并没有奏效。这是视频的截图一半。

这是我的代码：

    namespace Bloxel
{
    /// <summary>
    /// This is the main type for your game
    /// </summary>
    public class Game1 : Microsoft.Xna.Framework.Game
    {
        GraphicsDeviceManager graphics;
        SpriteBatch spriteBatch;

        public int WIDTH = 800;
        public int HEIGHT = 600;

        Video splash;
        VideoPlayer player;
        Texture2D videoTexture;

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

            graphics.PreferredBackBufferWidth = WIDTH;
            graphics.PreferredBackBufferHeight = HEIGHT;
            graphics.ApplyChanges();
        }

        /// <summary>

        protected override void Initialize()

        {
            // Create a new SpriteBatch, which can be used to draw textures.
            spriteBatch = new SpriteBatch(GraphicsDevice);
            splash = Content.Load<Video>("splash");
            player = new VideoPlayer();
        }

            if (GamePad.GetState(PlayerIndex.One).Buttons.Back == ButtonState.Pressed)

            if (player.State == MediaState.Stopped)

                player.IsLooped = false;

            base.Update(gameTime);

            if (player.State != MediaState.Stopped)
                videoTexture = player.GetTexture();

            Rectangle screen = new Rectangle(GraphicsDevice.Viewport.X, GraphicsDevice.Viewport.Y, GraphicsDevice.Viewport.Width, GraphicsDevice.Viewport.Height);

            if (videoTexture != null)
            {

                spriteBatch.Draw(videoTexture, screen, Color.White);

            }

            base.Draw(gameTime);

    }
}

Answer 1

正如Mike所说，问题是由系统更新引起的。要解决此问题，您需要进入Windows Update并删除“Windows 7安全更新（KB2803821）”。您只需右键单击更新并按删除即可完成此操作。

Answer 2

我不知道这是否有效，但您可以尝试：在绘图函数中将矩形更改为向量。

spriteBatch.Draw(videoTexture, Vector2.Zero, Color.White);

因为Vector2为零，它将出现在游戏屏幕的角落。
