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! W+ l$ {0 B2 l
to go$ w2 c- G* d8 C
if not any? turtles with [not stopped? ] [ stop ] ; R, ^1 V/ `- U7 t! f% l; h8 j C
ask turtles with [remainder who 5 = 0] [, E0 D6 q$ T" x( D" ]
set close-mates (turtles with [self != myself])with[
2 ]; M$ ]* c4 h+ ?# _2 B' X3 g(abs(xcor -(xcor-of myself)) < X-Dist + Wid )
+ e& I. ?( b7 x/ A5 [7 tand (abs(ycor -(ycor-of myself)) < Y-Dist + Dep ) # v8 U5 V X( c2 B
