网志。要求特定的乌龟做某事

Question

我想用机器人模拟一个汽车工厂，叫做 carriers. 在我的走法中，我试图要求一个没有工作的载体找到一个。cutter 并去找它。

如何要求具体的运营商做什么？

这是我目前所做的。

to setup-patches
  ask patches [

    if pxcor = 1 and pycor = 5 [set machine-type "standard-welder"]
    if pxcor = 5 and pycor = 1 [set machine-type "prestige-welder"]
    if pxcor = 5 and pycor = 5 [set machine-type "riveter"]

    if machine-type = "cutter" 
    [set pcolor red
    set status "import"]
    if machine-type = "standard-welder" 
    [set pcolor green
    set status "import"]
    if machine-type = "prestige-welder" 
    [set pcolor blue
    set status "import"]
    if machine-type = "riveter" 
    [set pcolor yellow
    set status "import"]
  ]
end

to Go

  let cutter patches with [machine-type = "cutter"]
    let standard-welder patches with [machine-type = "standard-welder"]
    let prestige-welder patches with [machine-type = "prestige-welder"]
    let riveter patches with [machine-type = "riveter"]

  let free-carriers carriers with [in-job? false]

  ask free-carriers [
     ;;on-job is a carrier-owned variable
      ask cutter [
        if status = "import" [
          set status "pending"
          face cutter ;; I want the carrier to face the cutter and move towards it
          fd 1

      ]
    ]
  ]
end```

我想你是想 free-carriers 找到一个状态为 "导入 "的切割器补丁，让该切割器改变状态，然后让载具向它移动。

ask free-carriers [
  ;;on-job is a carrier-owned variable
  let my-cutter one-of cutter with [status = "import"]
  if my-cutter != nobody [
    ask my-cutter [ set status "pending" ]
    face cutter ;; I want the carrier to face the cutter and move towards it
    fd 1
  ]
]

由于每个自由载具都是（随机）轮流这样做的，所以没有两个自由载具应该去找同一个切割器。这将随机选择一个合格的切割器。 如果你愿意，你可以让自由载具去最近的一个。
