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
objList = new ArrayList(); ArrayList redList = new ArrayList();// 红色方 ArrayList blueList = new ArrayList();// 蓝色方 ArrayList removeList = new ArrayList();// 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：
