NetLogo set [energy] of one of turtles

Question

我正在尝试在 NetLogo 中创建简单的模型，当两只乌龟相遇时，能量最多的那只将所有能量都分配给第二只乌龟。

我设置命令meet如

to meet    
  ask turtles[ let candidate one-of turtles-at 1 0
    if candidate != nobody [

      if [energy] of candidate > energy [
        set color [color] of candidate
        set energy energy + [energy] of candidate
        set [energy] of candidate 0 ;; ISSUE HERE
      ]

   if [energy] of candidate < energy [
        set color [color] of candidate ;; ?
        set [energy] of candidate [energy] of candidate + energy 
        set energy 0 
      ]

    ]
  ]

所以，我用 set energy energy + [energy] of candidate 重置了乌龟（自我）的能量，然后我用：set [energy] of candidate 0 但是我可以得到一条错误消息：这不是什么东西你可以在.

上使用“set”

我应该如何在交易期间重置 candidate 能量？同样在第二个 if 期间，如何将候选颜色设置为（自我）海龟自己的颜色？ (set color [color] of candidate)

        set color [color] of candidate
        set energy energy + [energy] of candidate
        set [energy] of candidate 0 ;; HERE ISSUE
      ]

     if [energy] of candidate < energy [
        set color [color] of candidate
        set [energy] of candidate [energy] of candidate + energy 
        set energy 0

Answer 1

set [...] of ... 语法仅存在于极旧版本的 NetLogo 中。

在当前的 NetLogo 中，您可以：

ask candidate [ set energy 0 ]

NetLogo set [energy] of one of turtles

NetLogo set [energy] of one-of turtles
