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
' g, K: P( F r: ]! x- @其中有一段如下
. {0 H5 h, ]- A! ]% @ask turtles with [ infected? = true ]
" ?) T4 M( b/ F/ s我原本以为这句会回传『所有』infected? = true 的 turtle! ]* q6 c( C1 f6 z3 d9 M! G8 Y
但看结果似乎不是这样。: f% q9 }: z7 Q' |9 K
/ n" c5 K* K' H# @" I假设所有符合条件的有 5 笔2 [- D. a9 U: i
有时候回传 1 笔,有时回传 3 笔,是不固定的
( j9 } w- P$ n; D2 q' x回头查语法定义$ @) E8 q, B) F! A% r4 B
with
+ h- t: [/ }* l! Z: j- B9 m. }agentset with [reporter]
" K9 H9 O: J3 f. Y5 X" V8 LTakes 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./ z# E h K- p) i2 `3 s, n7 I
它只说回传 agents satisfying the given condition
' e3 i' ~8 L- s3 S4 }7 ]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 ?

谢谢!
