java swing实现的扫雷游戏

详细代码见我的相应github仓库：

欢迎fork源码到你自己的仓库下面。
效果图:

java awt以及swing实现的扫雷游戏，实现了基本逻辑.主要用到了floodfill(漫水填充)算法和knuth-shuffling-algorithm(Fisher–Yates也被称作高纳德(Knuth)随机置乱算法,随机洗牌算法)

代码如下:

AlgoFrame.java

package Test;

public class AlgoFrame extends JFrame{

    private int canvasWidth;
    private int canvasHeight;

    public AlgoFrame(String title, int canvasWidth, int canvasHeight){

        this.canvasWidth = canvasWidth;
        this.canvasHeight = canvasHeight;

        AlgoCanvas canvas = new AlgoCanvas();
        setContentPane(canvas);
        pack();

        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        setResizable(false);

        setVisible(true);
    }

    public AlgoFrame(String title){

        this(title, 1024, 768);
    }

    public int getCanvasWidth(){return canvasWidth;}
    public int getCanvasHeight(){return canvasHeight;}

    // data
    private MineSweeperData data;
    public void render(MineSweeperData data){

    }

                    RenderingHints.VALUE_ANTIALIAS_ON);
            hints.put(RenderingHints.KEY_RENDERING, RenderingHints.VALUE_RENDER_QUALITY);
            g2d.addRenderingHints(hints);

            // 具体绘制
            int w = canvasWidth/data.M();
            int h = canvasHeight/data.N();

                        if(data.isMine(i, j))
                            AlgoVisHelper.putImage(g2d, j*w, i*h, MineSweeperData.mineImageURL);
                        else
                            AlgoVisHelper.putImage(g2d, j*w, i*h, MineSweeperData.numberImageURL(data.getNumber(i, j)));

        }
