如何让乌龟算出其他乌龟拥有的乌龟拥有值比自己大的数量？

我做了一个行人评估模拟。在这个模型中，有一个turtle-own value [dis-door1]，表示从turtle到door1的距离。我必须计算 [dis-door1] 比我小的其他海龟的数量，但我失败了。这是我试图这样做的代码：

ask people[
  set dis-door1 distancexy 15 0
  set dis-door2 distancexy 0 15
  set density1 (count people with [([dis-door1] of other people) < ([dis-door1] of myself)]) / [dis-door1] of myself
  set density2 (count people with [([dis-door2] of other people) < ([dis-door2] of myself)]) / [dis-door2] of myself
  ]

我希望有人可以帮助做到这一点。

您的代码大部分是正确的。

试试下面的。本质上，我删除了我自己的外部，因为我自己是谁的引用是指调用者的调用者——你可以直接访问 ask people [...here...] 范围内的 dis-door1

ask people[
  set dis-door1 distancexy 15 0
  set dis-door2 distancexy 0 15
  set density1 (count people with [([dis-door1] of other people) < ([dis-door1] of myself)]) / dis-door1
  set density2 (count people with [([dis-door2] of other people) < ([dis-door2] of myself)]) / dis-door2
  ]
