我真的是 NetLogo 编程的新手，我需要帮助。这只是我的第二个任务，我完成了大部分任务。我不得不让机器人在迷宫中行走。机器人只能在黑色斑块上行走（紫色斑块代表障碍物）。机器人可以前进、后退、左转和右转，它必须到达目标。当涉及到目标时，它必须停止。在作业的第一部分，我必须制作程序“迷宫”，它将挑选 15 个随机补丁并将它们涂成紫色（紫色代表障碍物），包括一个代表目标的绿色补丁。每次我调用该程序时，它都会给我带来不同的迷宫。我需要两件事的帮助：
我必须做一个新的程序，它总是会给我同样的迷宫（总是相同的 15 个紫色随机补丁）
我必须创建一个新程序“搜索”，这将使机器人走到目标，因为我只调用一次该程序。机器人必须环顾四周，并始终指向有更多空间的方向。如果在他周围的每个方向上都有相同数量的空闲补丁，机器人必须随机选择它要去目标的方向。当涉及到目标时，它必须停止。
这是我的代码：
