如何在xna中摆脱纵向不必要的黑色方块？

Question

我有一张图片，我将其设置为使得支持的唯一方向是肖像：

关于game1（）方法的

graphics.SupportedOrientations = DisplayOrientation.Portrait;

如何摆脱屏幕上下边缘的黑框？

这就是它的样子：

忽略那个29，这是我的fps监视器。

在改变方向之前：

更改后：

这是我的代码。你会注意到很多数组和添加内容，我会用它来做别的事情。现在，我并没有真正使用它：

    Texture2D mineField;

    Vector2 mineFieldLocation,
        numFontLocation;

    int[] fieldPos = new int[9];

    float[]
        minePosX = new float[9],
        minePosY = new float[9];

    SpriteFont numFont;

    int posAdder = 45,
        index = 0;

    Random randMinePos = new Random();

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

        graphics.SupportedOrientations = DisplayOrientation.Portrait;

       graphics.IsFullScreen = true;

        // Frame rate is 30 fps by default for Windows Phone.
        TargetElapsedTime = TimeSpan.FromTicks(333333);

        // Extend battery life under lock.
        InactiveSleepTime = TimeSpan.FromSeconds(1);
    }

    /// <summary>

    /// This is where it can query for any required services and load any non-graphic
    /// related content.  Calling base.Initialize will enumerate through any components
    /// and initialize them as well.
    /// </summary>
    protected override void Initialize()
    {
        // TODO: Add your initialization logic here


        // le sumo o resto a la x o y 45 para que caiga en el mismo medio del cuadrado
        mineFieldLocation = new Vector2(30, 70);

        numFontLocation = new Vector2(33, 65);

        for (int i = 0; i < fieldPos.Length; i++)
        {
            fieldPos[i] = posAdder;

            posAdder += 45;                
        }

        for (int i = 0; i < fieldPos.Length; i++)
        {
            minePosX[i] = fieldPos[randMinePos.Next(0, 9)];
            minePosY[i] = fieldPos[randMinePos.Next(0, 9)];
        }

        base.Initialize();
    }

    /// </summary>
    protected override void LoadContent()
    {
        // Create a new SpriteBatch, which can be used to draw textures.
        spriteBatch = new SpriteBatch(GraphicsDevice);

        mineField = Content.Load<Texture2D>("Minesweeper");

        numFont = Content.Load<SpriteFont>("NumberFont");

        // TODO: use this.Content to load your game content here

    protected override void Draw(GameTime gameTime)

        GraphicsDevice.Clear(Color.CornflowerBlue);

        spriteBatch.Begin();

        spriteBatch.Draw(mineField, mineFieldLocation, Color.White);

        spriteBatch.DrawString(numFont, "1", numFontLocation, Color.Green);

       // spriteBatch.DrawString(numFont, "0", new Vector2(minePosX[index],minePosY[index]), Color.Black);

        base.Draw(gameTime);

Answer 1

正如我在评论中所说，你需要设置首选的宽度和高度，但我会解释原因..

首先，SupportedOrientations州的文件

  

获取或设置启用自动旋转和缩放时可用的显示方向。

我不相信你确实启用了（不确定它是否默认）。继此之后，这个页面上还有一个关于Automatic Rotation and Scaling的链接，它提供了许多关于设置宽度和高度的提示......

如果你再看一下你的第三张图片，那就有必要了，因为你当前的高度看起来像你的宽度，这让我相信你现在的宽度现在是你之前的高度。所以要确定我会设置两个

Answer 2

当处于仅纵向模式时，您需要交换后缓冲区的宽度和高度值：

//For 480x800 (90* rotated wp7 device)
Graphics.PreferredBackBufferWidth = 480;
Graphics.PreferredBackBufferHeight = 800;

您在480x800屏幕上渲染了800x480后备缓冲区。这导致它成为信箱。
