用java完成一个可调难度大小的有动画的迷宫鼠

实现一个可调难度大小的迷宫鼠，需要用到Java编程语言和图形化界面库。下面是一个简单的实现过程：

1. 创建一个窗口，用于显示迷宫地图和迷宫鼠。

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

public class MazeGame extends JFrame {
    private Maze maze;
    private MazeMouse mouse;

    public MazeGame() {
        setTitle("Maze Game");
        setSize(500, 500);
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

        maze = new Maze(10, 10); // 创建一个 10x10 的迷宫
        mouse = new MazeMouse(maze, 0, 0); // 初始位置为左上角

        add(maze);
        add(mouse);

        setVisible(true);
    }
}

2. 创建一个迷宫类，用于生成和显示迷宫地图。

public class Maze extends JPanel {
    private int[][] map;
    private int rows, cols;
    private int cellSize = 20;

    public Maze(int rows, int cols) {
        this.rows = rows;
        this.cols = cols;
        map = new int[rows][cols];
        generateMaze();
    }

    private void generateMaze() {
        // 生成迷宫地图
    }

    @Override
    protected void paintComponent(Graphics g) {
        super.paintComponent(g);

        for (int i = 0; i < rows; i++) {
            for (int j = 0; j < cols; j++) {
                if (map[i][j] == 1) {
                    g.fillRect(j * cellSize, i * cellSize, cellSize, cellSize);
                }
            }
        }
    }
}

3. 创建一个迷宫鼠类，用于显示迷宫鼠和处理键盘事件。

import java.awt.event.KeyEvent;
import java.awt.event.KeyListener;

public class MazeMouse extends JPanel implements KeyListener {
    private Maze maze;
    private int row, col;
    private int cellSize = 20;

    public MazeMouse(Maze maze, int row, int col) {
        this.maze = maze;
        this.row = row;
        this.col = col;
        setSize(cellSize, cellSize);
        maze.addKeyListener(this);
        setFocusable(true);
    }

    @Override
    public void paintComponent(Graphics g) {
        super.paintComponent(g);
        g.setColor(Color.RED);
        g.fillOval(col * cellSize, row * cellSize, cellSize, cellSize);
    }

    @Override
    public void keyPressed(KeyEvent e) {
        int keyCode = e.getKeyCode();
        switch (keyCode) {
            case KeyEvent.VK_UP:
                if (row > 0 && maze.getMap()[row - 1][col] == 0) {
                    row--;
                }
                break;
            case KeyEvent.VK_DOWN:
                if (row < maze.getRows() - 1 && maze.getMap()[row + 1][col] == 0) {
                    row++;
                }
                break;
            case KeyEvent.VK_LEFT:
                if (col > 0 && maze.getMap()[row][col - 1] == 0) {
                    col--;
                }
                break;
            case KeyEvent.VK_RIGHT:
                if (col < maze.getCols() - 1 && maze.getMap()[row][col + 1] == 0) {
                    col++;
                }
                break;
        }
        repaint();
    }

    @Override
    public void keyTyped(KeyEvent e) {
    }

    @Override
    public void keyReleased(KeyEvent e) {
    }
}

4. 在 `generateMaze()` 方法中生成迷宫地图。这里使用深度优先搜索算法生成迷宫。

private void generateMaze() {
    Stack<Point> stack = new Stack<>();
    boolean[][] visited = new boolean[rows][cols];

    for (int i = 0; i < rows; i++) {
        Arrays.fill(map[i], 1);
    }

    int row = (int) (Math.random() * rows);
    int col = (int) (Math.random() * cols);
    map[row][col] = 0;
    visited[row][col] = true;
    stack.push(new Point(row, col));

    while (!stack.isEmpty()) {
        Point p = stack.peek();
        row = p.x;
        col = p.y;
        List<Point> neighbors = new ArrayList<>();
        if (row > 0 && !visited[row - 1][col]) {
            neighbors.add(new Point(row - 1, col));
        }
        if (row < rows - 1 && !visited[row + 1][col]) {
            neighbors.add(new Point(row + 1, col));
        }
        if (col > 0 && !visited[row][col - 1]) {
            neighbors.add(new Point(row, col - 1));
        }
        if (col < cols - 1 && !visited[row][col + 1]) {
            neighbors.add(new Point(row, col + 1));
        }
        if (neighbors.isEmpty()) {
            stack.pop();
            continue;
        }
        int selected = (int) (Math.random() * neighbors.size());
        Point next = neighbors.get(selected);
        int nextRow = next.x;
        int nextCol = next.y;
        map[nextRow][nextCol] = 0;
        visited[nextRow][nextCol] = true;
        stack.push(next);
    }
}

5. 在 `main()` 方法中创建迷宫游戏窗口。

public static void main(String[] args) {
    new MazeGame();
}
