Question

一个。我正在尝试在netlogo中设置供应链结构。每层的元素（即DistributionCenters）具有相同的xcor，我希望它们在ycor上均匀间隔（请注意DistrubutionCenters的数量是可变的，并使用滑块导入）。我已经尝试了很多方法并得出以下想法，但这些补丁不会使海龟发芽

breed [Producers Producer]
breed [DistributionCenters DistributionCenter]

to setup

  clear-all

  set-default-shape DistributionCenters "house ranch"
  let DCR1 (- floor ( n_DistributionCenters / 2 ))
  let DCR2 (  floor ( n_DistributionCenters / 2 ))
  let DistRange (range DCR1 DCR2 1)
  ask patches with [ pxcor = 0 and pycor = DistRange][sprout-DistributionCenters 1]

Answer 1

您的问题是您要问数字（pycor）是否等于列表。这些是不同类型的数据。因此，您的示例等效于此完整模型（已打印出列表）：

to testme
  clear-all
  let selected (range 0 15 3)
  print selected
  ask patches with [pxcor = 0 and pycor = selected] [set pcolor blue]
end

一种方法是分别使用foreach和ask适当的补丁遍历列表：

to testme2
  clear-all
  let selected (range 0 15 3)
  print selected
  foreach selected
  [ here -> ask patch 0 here [set pcolor blue]
  ]
end

或者，我认为这在概念上与您尝试执行的操作类似-它使用member?来测试列表的成员资格：

to testme3
  clear-all
  let selected (range 0 15 3)
  print selected
  ask patches with [pxcor = 0 and member? pycor selected] [set pcolor blue]
end

用pycor要求补丁=发芽海龟的范围
