Question

Don t know what this really means or what s causing this. My code is heavily modeled from the community model "Fire" The Error:

(Line 36) Expected a number here, rather than a list or block.

globals [
  initial-plants  
  triggered-plants    
]

breed [signals signal]   

to setup
  clear-all
  set-default-shape turtles "square"
  ask patches with [(random-float 100) < density]
    [ set pcolor green ]
  ask patches with [pxcor = min-pxcor]
    [ transmit ]
  set initial-plants count patches with [pcolor = green]
  set triggered-plants 0
  ask patches with [ pcolor = red ] [
    ; See if there is any possible neighbor patch
    ; to whom I can spread my lack of concentration
    let target one-of neighbors4 with [ pcolor = green ]

    ; if the target exists, have them change their color
    if target != nobody [
      ask target [ 
        set pcolor red
      ]
    ]
  ]
  reset-ticks
end

to go
  if not any? turtles  
    [ stop ]
  ask signal
    [ask neighbors4 with [pcolor = green]
      [ transmit ] ]
  tick
end

to transmit  
  start signal 1
    [ set color blue ]
  set pcolor black
  set triggered-plants triggered-plants + 1
end

你们使用“信号”这样说,但需要使用多元的“信号”。或具体指明了哪些信号,例如who- number (ask sign 1 [...)。这就是你描述的错误来自何处。

此外,由于你使用的未定义的<条码><>>>>>> /代码,你犯了一个错误,但我认为这是你正在做的事吗?
