Netlogo：[ifelse] 命令/预期命令

Question

我是netlogo的初学者。在代码下面，括号里好像有错误，但我还没有发现我的错误... 感谢您的帮助。

to exit
ask turtles [[
[ifelse patch-here = goal ; option A
[ifelse pcolor = gray ; option B (option A1)
[ifelse income = 0 ;option C (option B1)
  [die] ;option C1
  [ifelse count products >= 3 ;option B2
    [die][set turtles continue]]] ;option C2 
[set turtles continue]
] ; option B2
  [set turtles continue]]
 ; option A2
]]end

Answer 1

当您无法解决括号错误时，适当的缩进是您的朋友。这是您的代码：

to exit
ask turtles
[
  [
    [ ifelse patch-here = goal ; option A
      [ ifelse pcolor = gray ; option B (option A1)
        [ ifelse income = 0 ;option C (option B1)
          [die] ;option C1
          [ ifelse count products >= 3 ;option B2
            [die]
            [set turtles continue]
          ]
        ] ;option C2 
        [ set turtles continue
        ]
      ] ; option B2
     [ set turtles continue
     ]
   ]
 ; option A2

但是你的问题是你从 ask turtles [ [ [ 开始 - 应该有一个的三个左括号。
