NETLOGO：仅对满足条件的变量的乌龟发出命令-在“ foreach”之后

Question

用户，

我正在尝试命令具有各种变量的海龟。 我的代理商叫消费者。 每个“消费者”都有其颜色代表的不同需求（我使用14种颜色作为基准）。 当具有特定颜色的消费者数量达到10个以上时，我希望他们将颜色更改为白色。 我在下面使用代码，导致所有消费者将颜色更改为白色。 虽然我只需要满足变成白色的条件的“消费者”。

to cocreate-value
  let a count consumers with [ color = blue] 
  let b count consumers with [ color = gray] 
  let c count consumers with [ color = red]
  let d count consumers with [ color = orange]
  let e' count consumers with [ color = brown]
  let f count consumers with [ color = yellow]
  let g count consumers with [ color = green]
  let h count consumers with [ color = lime]
  let i count consumers with [ color = turquoise]
  let j count consumers with [ color = cyan]
  let k count consumers with [ color = sky]
  let l count consumers with [ color = violet]
  let m count consumers with [ color = magenta]
  let n count consumers with [ color = pink]

  ask consumers [set type-of-need ( list a b c d e' f g h i j k l m n ) ] 
  foreach type-of-need [
    if  ? > 10  [
        let z consumers with [ ? > 10] 
        ask z [ set color white ]
        ask consumers with [color = white] [set need? false]
   ]]
   end

有人可以告诉我解决方案吗？

谢谢

您的问题是您的列表由数字（每种类型的消费者的计数）组成，而不是需求类型本身。 创建print type-of-need后，您可以通过按需print type-of-need来看到它。 假设它看起来像[5 12 4 ...]。 然后，您遍历此数字列表，最终得到一个大于10的数字。在此示例中，现在有? = 12 ? = 12 。 这样，创建代理集z的条件将对所有消费者均成立。

以下代码未经测试，但是您需要列出类型而不是计数。 尝试这样的事情：

to cocreate-value
  let a count consumers with [ color = blue] 
  let b count consumers with [ color = gray] 

  ask consumers [set type-of-need ( list blue gray ) ] 
  foreach type-of-need [
    if  count consumers with [ color = ? ] > 10  [
        let z consumers with [ color = ? ] 
        ask z [ set color white ]
        ask consumers with [color = white] [set need? false]
   ]]
   end
