在这段代码中我设定了一个stopped？变量，初始状态设为false 。运行过程不能输出stopped？为true 。始终为false
& T% A6 B- d3 ~/ Vto go
! u# X! A& Z# \3 Aif not any? turtles with [not stopped? ] [ stop ] $ u4 e4 {8 S u7 X& s
ask turtles with [remainder who 5 = 0] [& @- f( O5 `3 R6 u, n* O
set close-mates (turtles with [self != myself])with[" z* C# a' \' ^' j) T, O3 S, Q
(abs(xcor -(xcor-of myself)) < X-Dist + Wid ) $ t$ M& E/ ]2 v/ a
and (abs(ycor -(ycor-of myself)) < Y-Dist + Dep )
