新手发问超简单问题,目前还处于研读范例码的阶段,边测边看结果来理解程序" w/ W3 @6 Y/ y; i
其中有一段如下
( ]# R! M+ B/ Z8 R" S9 bask turtles with [ infected? = true ] 0 q( y9 Z. z( }1 I
我原本以为这句会回传『所有』infected? = true 的 turtle5 A4 |( V u6 c# [
但看结果似乎不是这样。
0 O1 B' c: ^. C9 _
) l7 s5 G1 }; k3 ]! T假设所有符合条件的有 5 笔4 }2 g. Q' H2 X& T% B+ h
有时候回传 1 笔,有时回传 3 笔,是不固定的
$ z1 X% h4 M+ X回头查语法定义/ b+ c3 j; H6 s) Y3 F
with 5 A& K2 u4 O k7 b
agentset with [reporter]9 E8 T7 @" h3 M8 ~ B+ c0 N
Takes two inputs: on the left, an agentset (usually "turtles" or "patches"). On the right, a boolean reporter. Reports a new agentset containing only those agents that reported true -- in other words, the agents satisfying the given condition.8 b) F6 D8 X. E
它只说回传 agents satisfying the given condition2 b9 ]* C0 Q, N/ N' |
是否 with 回传的是『符合条件』的数据,而不是『所有符合条件』的数据 ?
