我正在创建一段代码，其中涉及一个迷宫和按下按钮时打开的门。问题是当我放入门时，玩家碰撞检测到门但不再检测到迷宫。我已经把我所有的代码放在这里，希望如果人们能看到任何其他问题，他们可以帮助谢谢:)

另外，如果有人能告诉我如何设置一个倒数计时器，它会禁用玩家并显示一个游戏结束标志，这也太棒了：D

由于游戏中的设计问题，添加门（或barriers您在代码中调用它们）会使墙壁碰撞无效。

这是您在主循环中执行的操作：

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

您首先检查墙壁的碰撞，然后再次检查与障碍物的碰撞。updateWall问题是你在那些和updateBarrier1方法中加入了让你的角色移动的部分。

因此，例如，如果您的角色与墙壁发生碰撞，但没有与门发生碰撞，则该角色仍会移动，因为该updateBarrier1方法不会检测到与障碍物（门）的碰撞并使他移动。

相反，您应该调用一些方法collides_wall并collides_barrier返回TrueorFalse然后将前面引用的两行替换为：

if not player.collides_wall(wall_list) and not player.collides_barriers(barriers):
    player.move()

使用move一种可以移动播放器的方法，就像您当前在updateSomething方法中所做的那样。

注意：有人在评论中指出，对于墙壁和障碍物的碰撞，您也不需要两个单独的方法，因为最终它们都是精灵，并且您对它们执行完全相同的操作。所以只需添加一个collides方法。
