KeyCode不工作

Question

我正在做一个游戏，它有一个数组，它代表一个岛，这个数组应该在你每次开始游戏时随机生成(我将在游戏结束时生成程序生成的部分)。而且，如果你点击箭头或wasd，它会让你看到你看不到的岛的某些部分。但我有一个问题:当我点击这个键时，什么也没有发生。

这是移动的代码(它在三个不同的类上)：

 //class Form
 private Game game = new Game();
    public int x = 0;
    public int y = 0;

    public GameWindow()
    {
        KeyPreview = true;
        KeyDown += new KeyEventHandler(GameWindow_KeyDown);
        InitializeComponent();
    }

    void GameWindow_KeyDown(object sender, KeyEventArgs e)
    {
        if (e.KeyCode == Keys.W)
        {
            y = -1;
        }
        else if (e.KeyCode == Keys.A)
        {
            x = -1;
        }
        else if (e.KeyCode == Keys.S)
        {
            y = 1;
        }
        else if (e.KeyCode == Keys.D)
        {
            x = 1;
        }
        game.Move(x, y);
    }

    private void panel1_Paint(object sender, PaintEventArgs e)
    {
        Graphics g = panel1.CreateGraphics();
        game.startGraphics(g, 100);
    }

    private void GameWindow_FormClosing(object sender, FormClosingEventArgs e)
    {
        game.Stop();
    }

    private void timer1_Tick(object sender, EventArgs e)
    {
        x = 1;
        y = 1;
        game.Move(x, y); // I put this to see if it works, but it still does nothing
    }
// class Game
public void Move(int x, int y)
    {
        if (x == -1 && gEngine.smallestXTileOnScreen == 0) { }
        else if (x == 1 && gEngine.smallestXTileOnScreen == size - 25) { }
        else if (y == -1 && gEngine.smallestYTileOnScreen == 0) { }
        else if (y == 1 && gEngine.smallestYTileOnScreen == size - 15) { }
        else
        {
            gEngine.smallestXTileOnScreen += x;
            gEngine.smallestYTileOnScreen += y;
            gEngine.render();
        }
    }
//class GraphEngine
public void render()
    {
        drawHandle.Clear(Color.Blue);
        for (int i = 0; i < 25; i++)
        {
            for (int j = 0; j < 15; j++)
            {
                prop = world[i + smallestXTileOnScreen , j + smallestYTileOnScreen];
                switch (prop)
                {
                    case 0:
                        drawHandle.DrawImage(sea, i * 50, j * 50, 50, 50);
                        break;
                    case 1:
                        drawHandle.DrawImage(plain, i * 50, j * 50, 50, 50);
                        break;
                    case 2:
                        drawHandle.DrawImage(mountain, i * 50, j * 50, 50, 50);
                        break;
                    case 3:
                        drawHandle.DrawImage(valley, i * 50, j * 50, 50, 50);
                        break;
                    default:
                        drawHandle.DrawImage(sea, i * 50, j * 50, 50, 50);
                        break;
                }
            }
        }
        Form Debug = new Form(); //Notice that I put here a form, if it's shown,
        Debug.Show();//then render() has been called. It doesn't show.
    }

编辑:我放了第一个类的全部代码，也许它可以帮助你…我不知道我应该做什么，我是Visual Studio的新手:/

好吧，由于某些原因，我的Visual Studio C# 2010版本似乎有一点buggy。在进行调试之前，我必须转到\bin\Debug文件夹并清空它，它可以使用普通代码+ keyPreview = true...希望这只是一个bug :/
