netlogo - 如何使一个补丁中的两只海龟都可见？

Question

我有两只乌龟——卖家和买家在一块，它们的形状"face happy" .
但是在我运行安装程序时的界面上，如果一个补丁中有两只海龟，我只能看到其中的一只。
我的问题是，我该如何编码才能看到它们。如果它不可能至少在某些补丁中看到另一个代理中的一个代理。

这是我的代码:

ask sellers
         [move-to one-of patches with [not any? turtles-here]] 

  ask buyers
         [move-to one-of patches with [not any? buyers-here]] 
    ask buyers [if any? sellers-here [set shape "face happy"]]
  ask buyers [if not any? sellers-here [set shape "face sad"]]
  ask buyers [if any? sellers-here [set color 67]]
  ask sellers [if any? buyers-here [set shape "face happy"]]
  ask sellers [if not any? buyers-here [set shape "face sad"]]
  ask sellers [if any? buyers-here [set color 137]]

假设在瓦片中心有两只海龟的瓦片:

 to spread-out   
   ask patches with [count turtles-here = 2]
    [ask one-of turtles-here [
        fd .25 
        ask one-of other turtles-here [face myself fd -0.25]]]
 end
