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
X" O% ~$ G# s4 @其中有一段如下2 e1 u3 g2 K& R9 l' M, X' h! |
ask turtles with [ infected? = true ] / ]1 x6 {# a6 E5 o
我原本以为这句会回传『所有』infected? = true 的 turtle
3 I/ H2 E2 q3 X1 E! p0 j但看结果似乎不是这样。
% q+ r! y" o& \, o3 y1 @2 [& v5 \6 ]* @& O9 v( h
假设所有符合条件的有 5 笔% d4 f4 q& H+ P4 J8 b0 T
有时候回传 1 笔,有时回传 3 笔,是不固定的
, v; \: M& |" S+ C' ^回头查语法定义1 K% O$ _9 \$ X. N F6 {" q

agentset with [reporter]( h! l1 A: Q. j, ]: O
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.
0 m" v. i# D, R它只说回传 agents satisfying the given condition- I4 |* g5 ^# Q% v" ^
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 ?
