python中的多壁碰撞

Question

我正在创建一段代码，其中包含一个迷宫和一个按钮被按下时会打开的门。问题是，当我把门放进去时，玩家的碰撞检测到了门，但不再检测到迷宫。我把我所有的代码都写在这里，希望如果人们能看到其他问题，他们可以提供帮助，谢谢：）

另外，如果有人可以告诉我如何设置一个倒计时，将禁用球员和显示一个游戏结束标志，这将是太棒了：D

Answer 1

由于游戏中的设计问题，添加门（或者barriers）会使墙碰撞失效。在

以下是您在主循环中执行的操作：

player.updateWall(wall_list)
player.updateBarrier1(barriers)

首先检查墙的碰撞，然后再次检查与障碍物的碰撞。 问题是，您在updateWall和updateBarrier1方法中加入了使角色移动的部分。在

因此，例如，如果角色与墙碰撞，而不是与门碰撞，则角色仍将移动，因为updateBarrier1方法不会检测到与屏障（门）的碰撞，并将使其移动。在

{{cd6}应该用行：

^{pr2}$

使用move一个方法，它可以像当前使用updateSomething方法那样移动播放器。在

注意：有人在评论中指出，对于墙和障碍物的碰撞，你也不需要两种不同的方法，因为最终它们都是精灵，你对它们的操作完全相同。所以只需添加一个collides方法。在
