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：
