如果将If添加到go命令中，则会收到错误消息

不能在海龟上下文中使用勾号，因为勾号仅用于观察者

这是我的围棋命令。搜索、吃、回家和书房都在我的命令中定义

能量也被定义为海龟拥有的一个全局变量

to go

  if ticks = day-length  [set day day + 1 create-next-day]


  ask adults [search eat]
  if energy < 20000 [ask adults [go-home den]]

 tick 

end

如果我把电话线拔出来

if energy < 20000 [ask adults [go-home den]]

它运行得很好，但我需要那条线或同等的线。请帮忙

如果能量<20000[询问成年人[回家巢穴]]将是围棋中的一个问题，如果能量看起来是一个海龟变量。这将使过程的上下文成为海龟上下文，而不是观察者上下文

编辑：

例如，如果能量是一个海龟变量，也许你的意思是

ask adults [if (energy < 20000) [go-home den]]

---

首先，您需要更加渐进地构建代码。您的代码中有多个部分不起作用，您不理解。尝试添加尽可能少的量，并确保在添加任何其他内容之前都能正常工作。目前您有三个不同的问题，代码的不同部分都有错误

关于艾伦回答中的上下文问题，可以这样想：变量“能量”属于海龟。这意味着，如果你有10只海龟，你有10个名为“能量”的变量，每只海龟一个。您正在检查哪一个是否已根据您的请求进行了更新。那么我将如何修复它？

to go
  if ticks = day-length
  [ set day day + 1
    create-next-day
  ]

  ask adults
  [ search
    eat
    if energy < 20000
    [ go-home
      den
    ]
  ]

  tick
