Java制作“简易王者荣耀”小游戏

第一步是创建项目 项目名自拟

第二部创建个包名 来规范class

然后是创建类 GameFrame   运行类

package com.sxt;
 
import java.awt.Graphics;
import java.awt.Image;
import java.awt.Toolkit;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.awt.event.KeyAdapter;
import java.awt.event.KeyEvent;
import java.util.ArrayList;
 
import javax.swing.JButton;
import javax.swing.JFrame;
 
public class GameFrame extends JFrame {
	// 窗口尺寸
	private int windowWidth = 1400;
	private int windowHeight = 700;
	// 双缓冲图片
	private Image offScreenImage = null;
	// 攻击图片
	private Image attack = Toolkit.getDefaultToolkit().getImage("img/attack.jpg");
	// 游戏背景
	Background background = new Background(this);
	// 游戏玩家
	Champion player = new ChampionHouyi(this);
	// 双方小兵
	MinionBlue mb = new MinionBlue(this);
	MinionRed mr = new MinionRed(this);
	// 防御塔
	Turret turret = new Turret(this);
	// 攻击按钮
	JButton attackButton;
	// 游戏元素列表
	ArrayList<GameObject> objList = new ArrayList<GameObject>();
	ArrayList<GameObject> redList = new ArrayList<GameObject>();// 红色方
	ArrayList<GameObject> blueList = new ArrayList<GameObject>();// 蓝色方
	ArrayList<GameObject> removeList = new ArrayList<GameObject>();// 存放将要删除的元素
 
	public void launch() {
		// 设置尺寸
		setSize(windowWidth, windowHeight);
		// 窗口居中
		setLocationRelativeTo(null);
		// 关闭事件
		setDefaultCloseOperation(3);
		// 用户不能调整窗口大小
		setResizable(false);
		// 标题
		setTitle("尚学堂王者荣耀");
		// 窗口可见
		setVisible(true);
		// 添加键盘监视器
		this.addKeyListener(new GameFrame.KeyMonitor());
		// 添加游戏元素
		objList.add(background);
		objList.add(player);
		objList.addAll(turret.turretList);
		blueList.add(turret.turretList.get(0));
		redList.add(turret.turretList.get(4));
 
		/**
		 * 攻击按钮
		 */
		attackButton = new JButton();
		attackButton.setSize(130, 132);
		attackButton.setLocation(1150, 430);
		attackButton.addActionListener(new ActionListener() {
			@Override
			public void actionPerformed(ActionEvent e) {
				// 按钮事件
				player.attack(redList);
			}
		});
		this.add(attackButton);
		player.addButton();
 
		while (true) {
			mb.createMinion(this, blueList);
			mr.createMinion(this, redList);
			turret.addTurret(this);
			repaint();
			try {
				Thread.sleep(25);
			} catch (Exception e) {
				e.printStackTrace();
			}
		}
	}
 
	public void paint(Graphics g) {
		// System.out.println(player.getX()+" "+player.getY());
		if (offScreenImage == null) {
			offScreenImage = this.createImage(5984, 4452);
		}
		Graphics gImage = offScreenImage.getGraphics();
		for (int i = 0; i < objList.size(); i++) {
			objList.get(i).paintSelf(gImage);
		}
		// 绘制攻击图片
		gImage.drawImage(attack, player.getX() + 500, player.getY() + 100, null);
		objList.removeAll(removeList);
 
		g.drawImage(offScreenImage, -player.getX() + 700, -player.getY() + 350, null);
		/**
		 * 添加按钮后不能调用键盘事件 因为程序的焦点变成了按钮 this.requestFocus() 把焦点重新改变到游戏界面上
		 */
		this.requestFocus();
	}
 
	// main方法
	public static void main(String[] args) {
		GameFrame gameFrame = new GameFrame();
		gameFrame.launch();
	}
 
	// 键盘事件
	private class KeyMonitor extends KeyAdapter {
		@Override
		public void keyPressed(KeyEvent e) {
			int key = e.getKeyCode();
			player.keyPressed(e);
		}
 
		@Override
		public void keyReleased(KeyEvent e) {
			int key = e.getKeyCode();
			player.keyReleased(e);
		}
	}
}

运行结果如下：
