Question

如果给定变量的阈值满足5个滴答声，我希望乌龟走到最靠近大多数乌龟的地方。

我的代码是：

to move
  let count-tick 5
  if var >= 9.5 [
    set count-tick count-tick - 1
    if count-tick = 0 [
      ask turtle [
        let nearest-group min-one-of (patches with [sum turtles >= 3] in-radius 3 ) [ distance myself ]
        move-to nearest-group ;; go to the biggest crowd near you
        ask turtle [ ;; once there do the following
          set shape "star"
          set color red
        ]
      ]
    ]
  ]  
end

我遇到的问题是：a）我不确定如何说the patch with >= 3 turtles closest to you at the given range of 3（上面尝试过的代码）和b）我怎么说once there, change your shape。

我想这就是你想要的：

to move
  let count-tick 5
  if var >= 9.5 [
    set count-tick count-tick - 1
    if count-tick = 0 [
      let nearest-group min-one-of (patches with [count turtles >= 3] in-radius 3 ) [ distance myself ]
      move-to nearest-group ;; go to the biggest crowd near you
      set shape "star"
      set color red
    ]
  ] 
end

首先，您已经在调用此移动过程的过程的ask turtles代码块内。因此，您不需要额外的ask turtles。在NetLogo词典中查找ask，对海龟进行迭代，依次运行每只海龟的所有代码。

第二，您需要count turtles而不是sum turtles，因为sum是要累加值。

请注意，这没有错误检查，如果半径3范围内没有补丁，且补丁中至少有3只乌龟，则可能会出现问题。
