总结

前言《布谷鸟闯关-升级版》是一个基于java的布谷鸟闯关游戏，鼠标左键点击控制鸟的位置穿过管道间的缝隙，需要做碰撞检测，监听键盘事件，背景图片的切换，障碍物管道产生时y轴上需要随机位置。

主要设计 1.设计游戏界面，用swing实现
2.设计背景
3.设计移动墙
4.设计布谷鸟
5.设计障碍物
6.设计背景音乐和音效
7.新增用户账号注册登录功能
8.引用mysql数据库，管理用户账号密码和储存排行榜等信息

? 需要提前创建好数据库"game",字符集选“utf8mb4”
? 然后执行mysql表结构和初始化数据脚本
? 修改代码里的DBUtils的参数值

9.新增游戏商城模块
10.新增排行榜模块

核心类

线程类用于重复绘图

public class playingThread implements Runnable { Scene stage; private Image iBuffer; private Graphics gBuffer; List rfs; user_inf user; MainFrame mainframe; Graphics g ; GameplayingFrame playingframe ; public static boolean flag = true; //控制计分板的变量 public int score = 0; //分数 playingThread(Scene stage,Graphics g,GameplayingFrame playingframe ,user_inf user,List rfs,MainFrame mainframe) {this.mainframe=mainframe; this.rfs=rfs; this.user=user; this.stage=stage; this.g=g; this.playingframe=playingframe; } @Override public void run() {while (!stage.ifGameOver()){stage.drawItems(g); //绘画stage.itemMove(); //物体移动//33ms刷新一次try {sleep(33); } catch (InterruptedException e) {e.printStackTrace(); }if(stage.ifGetScore()){score++; }stage.shift(score); //playingframe.update(g); //清除上一次绘画结果//双缓冲方法清除上一次绘画结果if (iBuffer == null){iBuffer = playingframe.createImage(playingframe.getSize().width,playingframe.getSize().height); gBuffer = iBuffer.getGraphics(); }playingframe.paint(gBuffer); g.drawImage(iBuffer,0,0,null); //stage.drawItems(g); //再绘画}user.setCoin(user.getCoin()+score); new user_dao().update(user); playingframe.setVisible(false); rank_information rf=new rank_information(); rf.setScore(score); rf.setName(user.getUser_name()); rfs.add(rf); new rank_dao().update_rank(rfs); newresultFrame(score,user,rfs,mainframe); System.out.println("game over"); }}

总结通过此次的《布谷鸟闯关-升级版》实现，让我对JAVA的相关知识有了进一步的了解，对java这门语言也有了比以前更深刻的认识。
java的一些基本语法，比如数据类型、运算符、程序流程控制和数组等，理解更加透彻。java最核心的核心就是面向对象思想，对于这一个概念，终于悟到了一些。
