不更新 Python3 的变量

Question

self.p 中的 x 和 y 不更新 self.p 是一个绘制变量

当您使用箭头键时，它们会更改 x，而按钮 x 在变量 P 中不会更改 ..................................................... ....................

self.P = pygame.Rect(self.x, self.y, self.width, self.height)

self.OB = pygame.Rect(self.oX, self.oY, self.width, self.height)

抱歉格式化

这是我的代码：

非常感谢任何帮助 也很抱歉格式化

如果我没有遗漏什么，在您发布的代码中，没有任何地方可以实际更改 P 和 OB 的值..？

请注意，这两个变量特定于您的类的实例。它们是“实例变量”
