python练习，飞机大战（1）小甲鱼

游戏基本设定 敌方共有大中小三款飞机 ，分为 高中低三种速度； 子弹的射程并非 全屏，而大概是屏幕长度的80%； 消灭小飞机需要 1发 子弹，中飞机 需要8发，大飞机需要20发； 每消灭一家小飞机得1000分 ，中飞机6000分，大飞机10000分； 每个30秒有一个随机的道具补给，分为两种道具，全屏炸弹 和双倍子弹； 全屏炸弹最多只能存放 3枚，双倍子弹可以维持18秒钟的效果； 游戏将根据分数逐步提高难度，难度的提高表示飞机数量的增多 以及速度的加快。 中飞机和大飞机增加血槽的显示；

道具补给还未实现，逐渐提高难度也没有实现，剩下的都实现了。

飞机的碰撞检测： 首先是类要继承pygame.sprite.Sprite，然后设置一个mask属性，用于完美检测，也就是飞机透明部分的内容碰撞不会击毁，self.mask = pygame.mask.from_surface(self.image)，enemies_dowm = pygame.sprite.spritecollide(me, enemies, False,pygame.sprite.collide_mask)#me这个 精灵是否跟Enemies里面的任何一个精灵有碰撞，如果有碰撞，返回跟他碰撞的精灵列表。

后面可能会继续写，不过现在我对爬虫比较好奇，想先学习爬虫了

关于字体和图片资源，好像 不能添加附件，有想要的可以留邮箱发给你~ ^ ^!
