问题描述
我正在编写此代码来构建一个简单的正方形，它可以左右移动，并且可以使用 pygame 中的 colliderect 函数在舞台上跳跃，但问题是当玩家（正方形）跳上舞台时，其 y 坐标更改为舞台的 y 坐标永远不会倒下。另一个大问题是，当玩家在舞台下方时，它不应该能够跳过顶部，但它确实可以。我的代码包含四页，第一页包含主循环，第二页包含播放器类，第三页包含舞台类，第四部分包含基本游戏功能

解决方法
根据我对您的代码的了解，您使用 colliderect 和 30x30 的碰撞框：colliderect(self.rect.x + dx,self.rect.y,30,30)
您的关卡或舞台为 80x10：pygame.Rect(0,540,80,10)
这意味着碰撞检测只会发生在舞台的特定部分。这是一个视觉效果，可帮助您更好地理解：
我相信这可能是您遇到问题的根源。与红色盒子碰撞后，你让它们传送到一半左右，此时它们仍在与盒子碰撞。这使他们不断地传送回原来的位置，因为他们总是被放回红盒子，因为他们正在与它发生碰撞。这可能会导致您的一些其他错误。
