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: Z# G1 X2 [, I2 m( R1 [$ M; s2 w/ L
to go+ ?+ e0 Q# j" f( U6 M1 \, Z1 V
if not any? turtles with [not stopped? ] [ stop ] 3 Y2 q' Z; S% v. ]) G
ask turtles with [remainder who 5 = 0] [8 j* J6 ]* |8 B5 S# A6 q0 ?9 X$ N
set close-mates (turtles with [self != myself])with[
9 D3 j- O: ^1 l4 Z) e2 `/ m# @(abs(xcor -(xcor-of myself)) < X-Dist + Wid )
( h1 _& a; s) s9 u( G2 hand (abs(ycor -(ycor-of myself)) < Y-Dist + Dep )
