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
$ j7 |7 X$ l/ v3 q3 F其中有一段如下
7 ~: f! ^0 ?1 iask turtles with [ infected? = true ]
5 P3 o, ]9 C d% @: a1 D: _5 l7 C* |7 i我原本以为这句会回传『所有』infected? = true 的 turtle/ k# s+ i9 G9 n5 F
但看结果似乎不是这样。" i8 h; ~ r" V
. a5 q/ e. }5 L* P假设所有符合条件的有 5 笔
5 G2 }2 }% n% e+ Y有时候回传 1 笔,有时回传 3 笔,是不固定的

agentset with [reporter]8 K5 q0 Y/ @1 M
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.* _. Q* C8 `0 Q
它只说回传 agents satisfying the given condition
& q3 y) l' ~. E8 z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 ?
