好的,我可以为你提供一些基础的代码,你可以在此基础上进行修改和完善:
```java
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class SnakeGame extends JFrame implements ActionListener {
private static final long serialVersionUID = 1L;
private JButton startBtn;
private JPanel gamePanel;
private JLabel scoreLabel;
private int score;
private Timer timer;
private int delay;
private int x[] = new int[300];
private int y[] = new int[300];
private int length;
private boolean leftDirection = false;
private boolean rightDirection = true;
private boolean upDirection = false;
private boolean downDirection = false;
private boolean inGame = true;
private int food_x;
private int food_y;
public SnakeGame() {
initUI();
}
private void initUI() {
// 设置基本界面
setTitle("贪吃蛇游戏");
setDefaultCloseOperation(EXIT_ON_CLOSE);
setSize(300, 300);
setLocationRelativeTo(null);
// 添加开始按钮
startBtn = new JButton("开始游戏");
startBtn.addActionListener(this);
JPanel topPanel = new JPanel();
topPanel.add(startBtn);
getContentPane().add(topPanel, BorderLayout.NORTH);
// 添加得分标签
scoreLabel = new JLabel("得分:0");
JPanel bottomPanel = new JPanel();
bottomPanel.add(scoreLabel);
getContentPane().add(bottomPanel, BorderLayout.SOUTH);
// 添加游戏面板
gamePanel = new GamePanel();
getContentPane().add(gamePanel, BorderLayout.CENTER);
// 初始化游戏参数
initGame();
}
private void initGame() {
length = 3;
for (int i = 0; i < length; i++) {
x[i] = 50 - i * 10;
y[i] = 50;
}
generateFood();
score = 0;
scoreLabel.setText("得分:" + score);
delay = 100;
timer = new Timer(delay, this);
inGame = true;
leftDirection = false;
rightDirection = true;
upDirection = false;
downDirection = false;
}
private void generateFood() {
int r = (int) (Math.random() * 29);
food_x = ((r * 10));
r = (int) (Math.random() * 29);
food_y = ((r * 10));
}
private void checkFood() {
if ((x[0] == food_x) && (y[0] == food_y)) {
length++;
score++;
scoreLabel.setText("得分:" + score);
generateFood();
}
}
private void checkCollisions() {
for (int i = length; i > 0; i--) {
if ((i > 4) && (x[0] == x[i]) && (y[0] == y[i])) {
inGame = false;
}
}
if (y[0] >= 300) {
inGame = false;
}
if (y[0] < 0) {
inGame = false;
}
if (x[0] >= 300) {
inGame = false;
}
if (x[0] < 0) {
inGame = false;
}
if (!inGame) {
timer.stop();
}
}
private void move() {
for (int i = length; i > 0; i--) {
x[i] = x[(i - 1)];
y[i] = y[(i - 1)];
}
if (leftDirection) {
x[0] -= 10;
}
if (rightDirection) {
x[0] += 10;
}
if (upDirection) {
y[0] -= 10;
}
if (downDirection) {
y[0] += 10;
}
}
@Override
public void actionPerformed(ActionEvent e) {
if (inGame) {
checkFood();
checkCollisions();
move();
gamePanel.repaint();
}
if (e.getSource() == startBtn) {
timer.start();
}
}
private class GamePanel extends JPanel {
private static final long serialVersionUID = 1L;
protected void paintComponent(Graphics g) {
super.paintComponent(g);
if (inGame) {
g.setColor(Color.red);
g.fillRect(food_x, food_y, 10, 10);
for (int i = 0; i < length; i++) {
if (i == 0) {
g.setColor(Color.black);
g.fillRect(x[i], y[i], 10, 10);
} else {
g.setColor(Color.gray);
g.fillRect(x[i], y[i], 10, 10);
}
}
} else {
g.setColor(Color.black);
g.drawString("游戏结束", 130, 150);
}
}
}
public static void main(String[] args) {
SwingUtilities.invokeLater(() -> {
SnakeGame game = new SnakeGame();
game.setVisible(true);
});
}
}
```
这段代码实现了一个简单的贪吃蛇游戏,包括开始按钮、得分标签、游戏面板等。你可以在此基础上进行修改和完善,实现更多的功能。
