这始终打印“不是F”，我希望仅在不返回F时才打印 P.S这是我的完整代码，如果您想查看 这是马里奥的娱乐。游戏运行良好，但是当玩家离开平台时，我无法增加重力。我需要做的是检测玩家（人）何时不在对象的x范围内。我有一个名为CollisionY（）的函数，该函数已经检查玩家是否在对象的x范围内（所有这些都位于while循环中），当它检测到x范围内的人时，我可以使该函数返回一个变量，但是由于某种原因，我无法检测到它不在对象x范围内

答案 0 :(得分：0)
问题是，您的collideY函数永远不会返回“ F”，因为您没有将其传递给类的实例。相反，您将类本身传递给它。
object是python内部类。不要命名变量object。
尝试将collideY方法更改为此
def collideY(man, bounds):
if man.x <= bounds.x + bounds.width and man.x + man.width >= bounds.x: # Checks if the player is inside the bounderies of a list of objects
return "F"
并调用collideY(man, bounds)
您正在传递一个类实例，但是如果您希望它可以工作，则应该传递一个像man这样的对象实例。
