Python +；=不支持的操作数类型：'；int'；和'；非类型'；

我无法解决此问题，我在main方法中给了PapperWalldry 1的值

您的第二个参数也直接为None：

    paddleWall.y+=paddleWallDirY
    return paddleWall

                paddle1.y = mousey
                paddle3.y = mousey - 100

        drawArena()

moveWall(pw, None)

请注意，

None

值可能是函数调用的结果，例如。

请显示您用于调用

moveWall

的代码。在调用时，PapperWalldry没有值，因此您在设置时出错it@JoaquinE.，请参阅，以获取关于提出包含代码的好问题的指导。（简而言之：它们应该包含足够的内容来重现问题——您应该测试它们在自己运行时是否重现了问题——但仅此而已）@ᴘᴀɴᴀʏɪᴏᴛɪs您能帮助我吗，我必须在明天早上之前完成这项工作。您能发布checkEdgeCollisionWall方法吗？我确实给了PapperWallDiry一个值，为什么是0？您在那里有一个循环，函数

checkEdgeCollisionWall

提供了一个新值

PapperWallDiry

，在某个时刻，返回

None

。
