01-显示敌机
1.创建敌机类
2.显示到屏幕
============================================================================================================================================
02-控制敌机左右移动
========================================================================================================================================
03-代码优化：子弹越界的问题
=====================================================================================================================================
04-敌机发射子弹
已完成
=======================================================================================================================================
05-敌机发射的子弹判断越界
已完成
=======================================================================================================================================
06-代码优化：抽取基类
已完成
=========================================================================================================================================
07-扩展：飞机爆炸效果
爆炸效果:短时间内替换图片
===============================================================================================================================================
未优化总代码
