【Python】从0到1：从头开始写打砖块小游戏~（四）

世界上最遥远的距离，不是生与死，而是......

你亲手创造出来的bug就在眼前，可你怎么也找不到！

Hi~ o(￣▽￣)ブ 我又双叒叕来啦~ 等你很久啦~
NOTE：楼主11岁女学生，文笔（排版风格）不好别介意啦~
NOTE2：这个游戏是我从头开始写的，所以会比较慢，就相当于检测一下这个疫情期间的学习成果吧~

关于这个游戏：

• 它是我从头开始写的，每天写多少发多少，所以可能会比较慢，每天写4，50行的话大概五天左右~
• 能力原因，每天在电脑前呆4，5个小时也就60行左右，再加上测试和改bug......
• 没有抄袭！没有抄袭！没有抄袭！

程序语言	Python
工具/原料	电脑，Pygame
其它	这个程序写完可能会比较久~

因为8月要参加奥数比赛，所以最近每天要花3，4个小时刷题，写Python的时间被严重压缩......呜~

昨天没发，今天把两天的代码都发了！（拖延症患者在此......各位大佬随便催更~）

上篇链接~：

                                   【Python】从0到1：从头开始写打砖块小游戏~（三）

截止到现在的所有代码~：（250行左右~）

哦吼！终于把碰撞检测写完了！我太难了......

 预计明天完结~

还剩主程序了！明天一定加油写完！我爱Python~

您的催更是我的动力~（某位不知名Python小白~）

尽情催更吧！

溜了溜了~
