Pygame colliderect 无法正常工作

Question

我正在编写这个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）在舞台上跳跃时，它的 y 坐标变为舞台的 y 坐标永久且永不倒下。另一个大问题是，当玩家在舞台下方时，它应该无法跳过顶部，但确实可以。我的代码有四页，第一部分是主循环，第二部分是玩家类，第三部分是舞台类，第四部分是游戏的基本功能

Answer 1

根据我对您的代码的了解，您使用 colliderect 与 30x30 的碰撞框：colliderect(self.rect.x + dx, self.rect.y, 30, 30)

您的关卡或关卡为 80x10：pygame.Rect(0, 540, 80, 10)

这意味着碰撞检测只会发生在你舞台的某个部分。这是一个视觉效果，可以帮助您更好地理解：

我相信这可能是您的问题的根源。与红色盒子碰撞后，您让它们传送到一半左右，此时它们仍在与盒子碰撞。这使得它们不断地传送回原来的位置，因为它们总是被放回红色盒子中，因为它们正在与它发生碰撞。这可能会导致您的其他一些错误。
