Question

我正在尝试获取单个进程（进程是乌龟）的who id，但出现此错误：“ cpu 0不是观察者运行PROCESS时的PROCESS错误。由过程GO调用。由按钮go调用“

我需要这个谁的id，因为我希望，如果可能的话，只有队列的第一个进程（具有最高优先级的进程）才能到达cpu的“未采用”核心。

我发现当我要求单次处理进行指令时，就会出现错误。它不在乎什么动作（我试图改变指令）。问题是“询问进程N [...]”。

to go

    if ticks > 0 and  ticks mod 10 = 0 and number-of-processes < max-number-of-processes
  [

      create-processes 1[
        set color green
        set shape "square"
        set size 2
        set xcor 0
        set ycor 0
      ]
      ;set whonumber  [who] of  process current-process  --> it'doesn't work.. same error below
      ask process current-process [set whonumber  who ] ; --> current-proces is a variable that start to 0.. yeah i've tried also to put 0 instead.. doesn't work
      set mylist lput one-of processes with[who = whonumber] mylist

      set number-of-processes  number-of-processes + 1
      set current-process  current-process + 1 ;verificare se quando muore un processo l'assegnazione sia sempre sequenziale oppure debba fare -1 in caso di die
  ]


  ;TO DO :  MOVE THE SPAWNED PROCESS TO THE (turtle)QUEUE IF POSSIBLE


  ask processes [show who]

   if any? cores with [core-taken = false] and number-of-processes > 0 [
   ; ask cores with [xcor =  ([xcor] of one-of other processes)] [set core-taken true]   ---> doesn't work.. the comand face doesn't reach the same core coord...
    ask processes with[ who  = [who] of process item 1 mylist]  [face  unused-core forward 1]  ; this action in the future will be done by the first project in the turtle queue

  ]

 tick
end

错误告诉您0号海龟实际上是品种cpu，而不是品种进程，但是您的代码将其视为进程。我的猜测是，列表中返回的数字为0，然后说ask process 0，然后NetLogo告诉您没有“进程0”。

这类问题就是为什么在代码中使用who数字通常不是一个好主意的原因。在创建乌龟时会按顺序分配它们。列表中没有who号，而是只列出了一些海龟。

试图获取单个<process>的谁的id：“ cpu 0不是<breed-name>。观察者运行<breed-name>时出错”
