答案 0 :(得分：0)
您的load_level函数需要level个参数，但它从不在任何地方使用它。
相反，它确实：
def load_level(level):
# ...
for row in levels:
for col in row:
现在，levels是一个级别列表，它是一个行列表，列是一串列。
但您正在执行for row in levels，这意味着您将每个级别命名为row，然后for col in row将该级别中的每一行命名为一列，并且整行永远不会是== "E"或您检查的任何其他内容。所以你得到一个空的平台列表和一个空的实体列表。
你可能想要的是：
def load_level(level):
# ...
for row in levels[level]:
解决了这个问题之后：我不认为你想让sprite小组entities充满1级精灵，然后添加2级精灵，然后等级3，等等，没有清除它们。
但这正是你正在做的事情。在main中，您将entities分配给空组。然后，在load_level内，您只需从外部函数调用add上的entities。然后，您返回同一entities，main分配给entities，它已经是entities。
我认为你想在load_level内创建一个新的platforms精灵组，就像你创建一个新的{{1}}列表一样。 （如果没有，你肯定不想要修改外部变量的误导性代码然后返回它的值只是为了将它重新分配给同一个变量......做一个或另一个，而不是两个。）
