请问在netlogo运行过程中出现了you can not use PREPARE in an observer context,because PREPARE is turtle/patch-only的问题怎么解决呀，不管怎么改都没有办法正常运行，麻烦各位友友帮忙看看是哪里的问题

引用 皆我百晓生 小程序回复内容作答：
根据你提供的代码，出现"you can not use PREPARE in an observer context,because PREPARE is turtle/patch-only"错误是因为你将prepare过程放在了go过程中，而prepare过程是用来设置turtles和patches的初始状态的，应该是在turtles-own和patches-own声明之后，在setup过程调用prepare过程。同时，你需要将所有的ask语句从prepare过程中移动到go过程中，因为在prepare过程中无法使用turtle和patch相关的命令。
修改后的代码如下：
