如何用java写一个随机生成迷宫的难度可调的有动画的迷宫鼠程序

以下是一个使用Java编写的随机生成迷宫的程序，其中包含可调整难度的选项和动画效果：

import java.awt.*;
import java.awt.event.*;
import java.util.*;
import javax.swing.*;

public class MazeGenerator extends JPanel implements ActionListener {

    private static final int ROWS = 25;
    private static final int COLUMNS = 25;
    private static final int CELL_SIZE = 20;

    private static final int DELAY = 50;

    private boolean[][] cellsVisited = new boolean[ROWS][COLUMNS];
    private boolean[][] wallsHorizontal = new boolean[ROWS + 1][COLUMNS];
    private boolean[][] wallsVertical = new boolean[ROWS][COLUMNS + 1];

    private Random random = new Random();

    private Timer timer;
    private int delay;

    public MazeGenerator(int delay) {
        this.delay = delay;
        setBackground(Color.BLACK);
        setPreferredSize(new Dimension(COLUMNS * CELL_SIZE, ROWS * CELL_SIZE));
        setDoubleBuffered(true);
        timer = new Timer(delay, this);
        timer.start();
    }

    public void actionPerformed(ActionEvent e) {
        generateMaze();
        repaint();
    }

    public void paintComponent(Graphics g) {
        super.paintComponent(g);
        drawMaze(g);
    }

    private void generateMaze() {
        int currentRow = random.nextInt(ROWS);
        int currentColumn = random.nextInt(COLUMNS);
        cellsVisited[currentRow][currentColumn] = true;

        while (true) {
            ArrayList<Point> neighbors = new ArrayList<Point>();

            if (currentRow > 0 && !cellsVisited[currentRow - 1][currentColumn]) {
                neighbors.add(new Point(currentRow - 1, currentColumn));
            }
            if (currentRow < ROWS - 1 && !cellsVisited[currentRow + 1][currentColumn]) {
                neighbors.add(new Point(currentRow + 1, currentColumn));
            }
            if (currentColumn > 0 && !cellsVisited[currentRow][currentColumn - 1]) {
                neighbors.add(new Point(currentRow, currentColumn - 1));
            }
            if (currentColumn < COLUMNS - 1 && !cellsVisited[currentRow][currentColumn + 1]) {
                neighbors.add(new Point(currentRow, currentColumn + 1));
            }

            if (neighbors.size() == 0) {
                break;
            }

            Point chosenNeighbor = neighbors.get(random.nextInt(neighbors.size()));

            int chosenRow = chosenNeighbor.x;
            int chosenColumn = chosenNeighbor.y;

            if (chosenRow == currentRow - 1) {
                wallsHorizontal[currentRow][currentColumn] = true;
            }
            else if (chosenRow == currentRow + 1) {
                wallsHorizontal[currentRow + 1][currentColumn] = true;
            }
            else if (chosenColumn == currentColumn - 1) {
                wallsVertical[currentRow][currentColumn] = true;
            }
            else if (chosenColumn == currentColumn + 1) {
                wallsVertical[currentRow][currentColumn + 1] = true;
            }

            currentRow = chosenRow;
            currentColumn = chosenColumn;
            cellsVisited[currentRow][currentColumn] = true;

            try {
                Thread.sleep(DELAY);
            } catch (InterruptedException e) {
                e.printStackTrace();
            }
        }
    }

    private void drawMaze(Graphics g) {
        g.setColor(Color.WHITE);

        for (int i = 0; i <= ROWS; i++) {
            for (int j = 0; j <= COLUMNS; j++) {
                if (wallsHorizontal[i][j]) {
                    g.drawLine(j * CELL_SIZE, i * CELL_SIZE, (j + 1) * CELL_SIZE, i * CELL_SIZE);
                }
                if (wallsVertical[i][j]) {
                    g.drawLine(j * CELL_SIZE, i * CELL_SIZE, j * CELL_SIZE, (i + 1) * CELL_SIZE);
                }
            }
        }
    }

    public static void main(String[] args) {
        JFrame frame = new JFrame("Maze Generator");
        MazeGenerator maze = new MazeGenerator(DELAY);
        frame.add(maze);
        frame.pack();
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.setLocationRelativeTo(null);
        frame.setVisible(true);
    }
}

这个程序使用Java Swing库来绘制迷宫，其中包含一个可调整的延迟参数，用于控制动画速度和难度。程序使用深度优先搜索算法来生成迷宫，每次随机选择一个未访问的邻居作为下一个位置，并在生成墙壁时使用延迟来创建动画效果。最终的迷宫是由水平和垂直墙壁组成的网格，可以通过绘制线条来实现。
