pygame制作第一天

 截个图

首先还是黑屏哈。后面找时间慢慢做地图跟其他角色，还有攻击方式等。

这里先做了一个“炫酷”的雨云召唤技能。

人物可以移动，g键召唤持续10秒的跟随目标的雨云。角色会被雨滴攻击。

思路很重要，不然数据传递就乱了。

雨滴是单个的，与其他元素无关（除了要传入攻击目标）。

云里面生成雨滴对象的集合，雨滴的x范围在与的[x,x+cloud.width]内

云需要跟随目标（这里暂定是玩家自己)需要定义其x,y的速度，以及方向。

人物我做了个基类charactor，玩家player继承基类。未雨绸缪哈

charactor.py

class Charactor(object):     def __init__(self, x=0, y=0):         self.x = x         self.y = y      def attack(self):         pass      def update(self, keys):         pass      def draw_damage(self, damage, window):         pass      def draw(self, delta, window):         pass
