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' ~8 p0 D$ a& R! I% V, B
其中有一段如下0 M# i% M# M# w0 I9 d
ask turtles with [ infected? = true ] 2 `7 D& n1 T% ?( {" d+ l
我原本以为这句会回传『所有』infected? = true 的 turtle6 n3 ?- V) t: ~/ Q
但看结果似乎不是这样。
% w' z. x) ^* F9 _0 u& l- s; @) v7 v1 M0 |: s- A# |
假设所有符合条件的有 5 笔
" [, G. Y" f' o0 r有时候回传 1 笔,有时回传 3 笔,是不固定的
8 r" B+ X0 R+ j回头查语法定义! ^# ]% {( f' ?* }- ~; N! \9 h
with . T9 F X% ^* W$ B$ r9 s
agentset with [reporter]
. k+ P1 e1 d/ G, b z% t8 dTakes 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.
D+ z$ F* A+ c2 H* V" [, m' C它只说回传 agents satisfying the given condition
( m5 g ~% ` \ m% e* Y0 \0 j6 J- u; i4 ^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 ?
5 l4 H" G* Q, i3 V' o
7 l5 C7 }6 G9 t# ?想确定一下) ` o {/ ~6 N4 N/ j8 _- P
谢谢!9 N* R7 U0 [2 j
