Question

是的，我已将我的赛道添加到我将要制作的赛车游戏中，现在我正试图将赛车添加到赛道上，但是当我加载赛车时，赛车的尺寸太大了。这是我调试时的显示方式......

没有错误或任何东西，但为什么它如此超大？请告诉我重新编辑的代码，了解如何修复它。谢谢！

这是我的编码;

public class Game1 : Microsoft.Xna.Framework.Game
{

    Texture2D background;
    Rectangle mainFrame;
    GraphicsDeviceManager graphics;
    SpriteBatch spriteBatch;
    Texture2D car1Texture;
    Vector2 car1Position = new Vector2(400f, 100f);

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



    /// <summary>
    /// Allows the game to perform any initialization it needs to before starting to run.

        graphics.PreferredBackBufferWidth = 1000;
        graphics.PreferredBackBufferHeight = 800;
        graphics.ApplyChanges();
        base.Initialize();
    }

    /// <summary>
    /// LoadContent will be called once per game and is the place to load
    /// all of your content.
    /// </summary>
    protected override void LoadContent()
    {
        // Create a new SpriteBatch, which can be used to draw textures
        spriteBatch = new SpriteBatch(GraphicsDevice);
        // Load the background content.
        background = Content.Load<Texture2D>("roadscan");
        // Set the rectangle parameters
        mainFrame = new Rectangle(0, 0, GraphicsDevice.Viewport.Width, GraphicsDevice.Viewport.Height);

        spriteBatch = new SpriteBatch(GraphicsDevice);
        car1Texture = Content.Load<Texture2D>("car1");

    }

            this.Exit();

            this.Exit();

        KeyboardState keyboard = Keyboard.GetState();
        GamePadState gamePad = GamePad.GetState(PlayerIndex.One);

        // Start building the sprite.
        spriteBatch.Begin();

Answer 1

您正在使用

SpriteBatch.Draw (Texture2D, Rectangle, Color)

这使您的汽车精灵占据Rectangle的位置和大小。我建议你使用版本

SpriteBatch.Draw (Texture2D, Vector2, Color)

而Vector2是Sprite的位置。查看所有不同版本的MSDN。

所以它会是：

spriteBatch.Draw(car1Texture, car1Position, Color.White);

Answer 2

你的问题在于：

    spriteBatch.Draw(car1Texture, mainFrame, Color.White);

您已将'mainFrame'定义为屏幕大小，因此您的汽车会拉伸到屏幕大小。将'mainFrame'替换为'car1Position'，一切都应该运行得更顺畅。

Texture2D在XNA 4.0中超大尺寸？
