建立两个精灵并搭建背景元素
粽子和爱心
先是建立一个粽子对象，也就是一个精灵，类里面需要继承pygame.sprite.sprite类，这是碰撞模块的重要部分。update函数是控制粽子方向，并防止粽子跑出边界，当粽子触碰到边界时出发触底反弹功能，使粽子向边界另一方向反弹移动。

背景搭建
直接导入图片并在循环中显示
bg = pygame.image.load("vack.jpeg").convert()
#下句需在游戏主循环中使用
screen.blit(bg, (0, 0))搭建完成后为

碰撞模块
碰撞部分我可是煞费苦心啊，使用以下语句， 尤 其 是 ！ ！ \color{blue}{尤其是！！} 尤其是！！我一开始以为没有碰撞，添加多个语句，实际上他发生了,只是我没有加语句->在此条件下会发生什么，造成这个惨案…
我们来好好分析这段条件，player 是粽子对象，group是一个包含❤的组，pygame.sprite.collide_circle_ratio(0.5)可以控制图片碰撞体积，于是碰撞条件达成！
if pygame.sprite.spritecollide(player,group,True,pygame.sprite.collide_circle_ratio(0.5)) : 语句
贪吃模块
当达到碰撞时把❤吃掉，设l为一个空数组，用l.append(aixin)加入❤实例，当数组l存在时，进入碰撞环节，碰撞后用pop函数删除❤。
然后加入判断，若数组l为空，则新加入❤游戏实例，也就是上述❤实例
for each in l:
each.Move_update()
screen.blit(each.image, each.rect)
if pygame.sprite.spritecollide(player,group,True,pygame.sprite.collide_circle_ratio(0.5)) :
l.pop()
score += 1
print(score)
# del aixin
if not l:
l.append(Heart_game())
group.add(l[0])计数机制
用score计算，引用一个ttf字体文件
score = 0
score_font = pygame.font.Font("font.ttf",50)
score_text = score_font.render("Score: % s" % str(score), True, BLACK)
screen.blit(score_text, (0, 0))最终呈现为
