Question

我正在努力弄清楚如何告诉我的海龟向前移动一个空置的补丁，一旦它们已经被称为“转龟”的程序转过来。

     let ahead patch-ahead 1
     let vacant-ahead ahead  with [not any? turtles-here ] ;;this line needs fixing 
      if any? turtles      
                   [turn-turtle if vacant-ahead [fd 1]]

它产生了这个错误，我理解，但无法解决如何修复。

WITH expected input to be an agentset but got the patch (patch 1 -2) instead.
error while solute 2 running WITH
  called by procedure MOVE-TURTLE
  called by procedure GO
  called by Button 'go'

以更易读的方式回复一些评论：对不起我不认为我解释得很好，因为我刚刚拿出了一小部分代码。也许这更有意义。

to go 
ask turtles 
[move-turtle] 
end 

to move-turtle 
turn-turtle 
if (not any? turtles-on patch-ahead 1) 
[fd 1] 
end

所以我只是想让这段代码将已经被“转龟”转向的海龟移动到前面一个空的补丁1，最好占用整个补丁，就好像它们是“发芽的”一样。谢谢！

如果你真的希望ahead成为一个补丁，那么听起来你想要做一些不同的事情。也许

to move
  ifelse (any? turtles-on patch-ahead 1) [
    turn-turtle
  ][
    fd 1
  ]
end

在NetLogo中将海龟移到空置的补丁中
