前面生成了運(yùn)動(dòng)、生成食物的算法。這次增加吃食物的算法：
1、創(chuàng)建生成食物的標(biāo)志build_food_state，在主程序中判斷，如果標(biāo)志需要?jiǎng)?chuàng)建食物，則生成。如果食物還存在，就不生成食物。
2、吃到食物的判斷：如果生成下一個(gè)食物的坐標(biāo)數(shù)組與食物的坐標(biāo)數(shù)組相等，則不消除最后尾的塊，同時(shí)更新生成食物的標(biāo)志為真。如果沒(méi)有吃到食物，則消除尾部塊。

# 如果加入的方塊等于食物，則不刪去尾塊
  if disp_List[-1] == disp_food:
    buid_food_state = 1
  else:
    del disp_List[0]
