C语言及Easy X飞实现机大战
在看完童晶老师的C语言游戏设计之后，我和基友老郭也动手做了一款飞机大战，由于课业繁忙，故难免有瑕疵和纰漏，如果读者发现问题，欢迎指出。
第一步，实现我方飞机及敌方飞机的飞行，发射子弹等等。
其思想是建立一个结构体，用来定义我方飞机和地方飞机的位置，血量，子弹种类，等等。其中位置除了中心位置center_x, center_y外还设了left_x, left_y等坐标，目的是为了将各个点的坐标都与中心坐标相关联，增强坐标的关联性。判断子弹是否射中敌机比较好判断，
不做赘述，判断敌机是否撞到我机及其敌机子弹是否射击到我机时用到了abs函数，因为我方飞机是可以移动的，不能简单的通过纵坐标的
大小来比较，以敌机撞到我机举例，首先判断纵坐标方向，my_plane.center_y（我机的中心纵坐标）- enemy_plane[0].center_y(敌机的
中心纵坐标) <= my_plane_high / 2 + enemy1_plane_high / 2 - 20,因为当我机头部(top)与敌机头部(bottom，整个游戏的头尾都是按照
我机的方向）恰好碰到时，两个飞机的中心纵坐标之差是等于my_plane_high / 2 + enemy1_plane_high / 2，再减20是为了使图形更直观，
但因为我机可以移动，也可能存在敌机在下，我机在上的情况，故用绝对值做差。

第二步将enemyplane_Num设为5，使用for循环初始化enemy_plane结构体数组，将所有原来是enemy_plane[0]的地方改为for循环，值得
注意的是，我在第二步中，对第一步的代码做了优化，比如敌机发射子弹我加入了限制条件enemy_plane[k].bottom_y > 15，因为若不加
限制条件，我们想让敌机不同时出现则需将其纵坐标设为负值，然而数组中的纵横坐标又不能出现负值。

第三步是将结构体数组中的bullet进行随机初始化赋值，赋值范围是0~19，0~16为普通小飞机，17、18是小boss，19是陨石，打爆后可获得
奖励，当吃掉奖励后子弹威力可+1，因为敌机bullet不同，所以根据bullet不同打印不同的敌机，同时根据bullet不同对我方伤害也不同，
这一步值得注意的就是当bullet==19时，当将它打爆了后要打印新的图片，即为reward，且reward在碰到我机或到底端时依旧在向下飞。
