Question

我想设置球权人，但是它不起作用，而是没有人。这是我的代码：

to setup
  clear-all
  reset-ticks
  setup-players-red
  setup-players-blue
  setup-ball 
  print BALL-OWNER
end


to setup-ball
  create-balls 1 [
    setxy 5 -1
    set shape "ball basketball"
    set size 2.5
    set the-ball self
    set BALL-OWNER one-of players with [distance the-ball = 0]
    set owner BALL-OWNER
  ]
end

to setup-players-red
  create-players 1[
    set color red
    set shape "person"
    set size 5
    setxy (5)
    setxy (-1)
    set team "red"
  ]

end

to setup-players-blue 
create-players 1[
    set color blue
    set shape "person"
    set size 5
    setxy (-5)
    setxy (1)
    set team "blue" 
  ]
end

那么，为什么我要打印“ nodoby”而不是玩家1/2？我究竟做错了什么？我还尝试将

”将[球距离= 0]设置为拥有一员的BALL-OWNER”。

在设置语句中，但我得到相同的结果。

如果可能，请尝试以Minimum, Complete, and Verifiable Example的形式提交代码，以便用户可以将您的代码复制并粘贴到空白的NetLogo实例中并运行您的模型。

您为玩家使用的setxy代码是有问题的-如果已解决，则不会出现与您描述的错误相同的错误-以下代码将为我运行：

globals [ ball-owner the-ball owner ]

breed [ players player ]
breed [ balls ball ]

players-own [ team ]

to setup
  clear-all
  reset-ticks
  setup-players-red
  setup-players-blue
  setup-ball 
  print BALL-OWNER
end


to setup-ball
  create-balls 1 [
    setxy 5 -1
    set shape "circle"
    set size 2.5
    set the-ball self
    set BALL-OWNER one-of players with [distance the-ball = 0]
    set owner BALL-OWNER
  ]
end

to setup-players-red
  create-players 1[
    set color red
    set shape "person"
    set size 5
    setxy 5 -1
    set team "red"
  ]

end

to setup-players-blue 
create-players 1[
    set color blue
    set shape "person"
    set size 5
    setxy -5 1
    set team "blue" 
  ]
end

尝试设置玩家时，Netlogo没有任何人
