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/ h! Y3 i0 Z/ }8 d
to go* F, G# U7 j( Z6 {
if not any? turtles with [not stopped? ] [ stop ]
* ~' y' r' ^: g4 l* Z$ ?ask turtles with [remainder who 5 = 0] [$ R, A5 X! Q3 Y% w! }
set close-mates (turtles with [self != myself])with[
# r6 D. \; m# i) w& z- z- g" E$ }(abs(xcor -(xcor-of myself)) < X-Dist + Wid ) - e1 y% |8 E4 y0 s/ }: U
