如何在NetLogo中创建迷宫墙？

Question

我正在尝试创建一个有 2 个出口的 5x5 网格，并在其中放置一些墙。换句话说，我想创造一个迷宫或迷宫。

我想知道是否有办法使边框线变粗或仅更改补丁一侧的颜色。

我想只放一名特工进去，并通过奖励他一些积分让他找到出口。 （Q-学习算法）

有人有想法吗？

如果这是不可能的，您可以建议类似的代码吗？

这是我想要创建的示例：

按照要求，我已经发布了我的一些工作（尽管手动完成此操作似乎效率低下）。这是我到目前为止所得到的：

同样，这是一种低效的方法。如果我继续使用这种方法，如何将 4 个补丁合并为 1 个补丁，以便我可以将我的代理输入其中并居中？

先感谢您。

Answer 1

要突出显示补丁的边缘，您需要使用乌龟。制作一个仅由一条线组成的海龟形状，然后创建具有该形状的海龟并相应地放置它。您可能想要使用单独品种的海龟（例如，称它们为“墙”）。

一旦你创建了乌龟，如果你想稍后用它做一些事情，你可以保留它，或者你可以让它“戳死”来杀死它，但首先让它在绘图中留下自己的图像。

Answer 2

尝试查看这个迷宫制造者 netlogo 模型中的代码。该算法的基本思想是使用随机行走者，在行走时建造墙壁（路径）。当他到达死胡同时，他会被传送到之前转弯的地方。

玩得开心！如果您想更深入地研究，当然有关于迷宫生成算法的维基百科条目。
