我很乐意承认这段代码很奇怪，而且是一种非常非正统的创建任何 2.5D 的方式，但是如果有人能看到发生了什么，我将不胜感激。

我的代码结果如图所示： 奇怪的曲面

我当然想要一个完全平坦的平面，但是我不确定它为什么会这样弯曲。如果有人有任何答案，代码如下所示：

公共静态int宽度= 640；公共静态int高度= 480；

private Image image;
private Graphics imageG;

private int mapWidth = 20, mapHeight = 15;

private int[] map;

private float x, y;

public Game(String title)
{
    super(title);
}

@Override
public void render(GameContainer gc, Graphics g) throws SlickException
{
    imageG.setBackground(Color.black);
    imageG.clear();

    for (int y = 0; y < mapHeight; y++)
        for (int x = 0; x < mapWidth; x++)
        {
            switch (map[x + y * (mapWidth)])
            {
            case 0:
                imageG.setColor(Color.green);
                break;
            case 1:
                imageG.setColor(Color.yellow);
                break;
            }

            imageG.fillRect(x * 32, y * 32, 32, 32);
        }

    imageG.flush();

    Image frustrum;

    for (int i = 0; i < 240; i++)
    {
        frustrum = image.getSubImage((int) (x - i), (int) (y - i), 32 + 2 * i, 1);
        frustrum.draw(0, height - 1 - i, width, 1);
        //g.drawImage(frustrum, x - i, y - i);
    }

    //g.setColor(Color.blue);
    //g.fillRect(x, y, 32, 32);
}

@Override
public void init(GameContainer gc) throws SlickException
{
    try
    {
        image = new Image(width, height);
        imageG = image.getGraphics();
    } catch (SlickException e)
    {
        e.printStackTrace();
    }

这是我的第一篇文章，如果事情看起来有点混乱，很抱歉。我相信我最终会习惯的...
