游戏规则
用pygame动画实现神庙逃亡类似的小游戏，当玩家移动的时候躲避子弹，如果子弹命中玩家或者名字龙都会减速，玩家躲避子弹使更多的子弹打在龙上，当玩家被龙抓到，则游戏输，如果龙被子弹减少速度，与玩家有一定的距离，则玩家获胜。

class MySprite(pygame.sprite.Sprite): def __init__(self, target): pygame.sprite.Sprite.__init__(self) self.master_image = None self.frame = 0 self.old_frame = -1 self.frame_width = 1 self.frame_height = 1 self.first_frame = 0 self.last_frame = 0 self.columns = 1 self.last_time = 0 def _getx(self): return self.rect.x def _setx(self, value): self.rect.x = value X = property(_getx, _setx) def _gety(self): return self.rect.y def _sety(self, value): self.rect.y = value Y = property(_gety, _sety) def _getpos(self): return self.rect.topleft def _setpos(self, pos): self.rect.topleft = pos position = property(_getpos, _setpos) def load(self, filename, width, height, columns): self.master_image = pygame.image.load(filename).convert_alpha() self.frame_width = width self.frame_height = height self.rect = Rect(0, 0, width, height) self.columns = columns rect = self.master_image.get_rect() self.last_frame = (rect.width // width) * (rect.height // height) - 1 def update(self, current_time, rate=30): if current_time > self.last_time + rate: self.frame += 1 if self.frame > self.last_frame: self.frame = self.first_frame self.last_time = current_time if self.frame != self.old_frame: frame_x = (self.frame % self.columns) * self.frame_width frame_y = (self.frame // self.columns) * self.frame_height rect = pygame.Rect(frame_x, frame_y, self.frame_width, self.frame_height) self.image = self.master_image.subsurface(rect) self.old_frame = self.frame def __str__(self): return str(self.frame) + "," + str(self.first_frame) + \ "," + str(self.last_frame) + "," + str(self.frame_width) + \ "," + str(self.frame_height) + "," + str(self.columns) + \ "," + str(self.rect) |
MySprite继承精灵类，因为在做动画时候，需要许多的参数，这里进行了初始化，master_image 图片的位置，frame、old_frame分别储存第一帧和上一帧的位置，frame_width和frame_height保存宽高，first和last保存帧的第一帧和最后一帧。columns保存列数。last_time时间变量。
X、Y、pos保存精灵的位置x和y的位置。
load载入，赋予对应精灵的值，(rect.width // width) * (rect.height // height) - 1，通过给定的图片的宽高除以参数的值，-1就是初始的位置是从0开始的。
update更新的时候，根据传入的时间和间隔频率，如果时间大于上次时间和间隔则改变帧数，如果帧数改变对应的图片位置也改变，实现动态变化。

加载龙，实现龙动画，这里没有龙的位移，玩家躲子弹或者命中子弹都会导致双方的x坐标减少，这里没使用对应的速度改变，减少游戏的开发难度。

def reset_arrow(): y = random.randint(250, 350) arrow.position = 800, yarrow = MySprite(screen)arrow.load("flame.png", 40, 16, 1)arrow.position = 800, 320group.add(arrow) |
子弹因为只有一个，如果击中则需要重置，这里写了重置子弹的函数便于调用，random.randint(250, 350)给子弹一个随机的高度。使游戏与变化。

player_start_y记录玩家初始的y坐标判断玩家是否处于跳跃状态中。
