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, I% R: f0 I' a, @$ r9 d$ N' i
其中有一段如下
8 m0 F9 B4 `+ W( ^ask turtles with [ infected? = true ] , s7 e; R% T: O
我原本以为这句会回传『所有』infected? = true 的 turtle9 K2 k; g# F3 g# e9 M& m# E
但看结果似乎不是这样。
/ A o; d- i8 [$ ? ~9 X* E' o) k- m( q+ H1 `* o" d. i( A" y
假设所有符合条件的有 5 笔
3 x* R6 K8 s5 K( ^) V" Z8 ?( y: d有时候回传 1 笔,有时回传 3 笔,是不固定的
+ `3 l. z3 }7 N4 ^回头查语法定义
% O* ]9 o% M8 P; r) Z; }/ Dwith ( E5 K0 ?3 Q8 }# F7 E0 _. ?8 K
agentset with [reporter]5 t4 g2 v: d6 v: C2 j3 G
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.5 M$ ?! M- y! t( s) \4 P6 t
它只说回传 agents satisfying the given condition0 E: Z* t3 D' M
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 ? ' f" U/ }/ s! ]( l* C
+ y6 d/ t" j6 ?+ B: I
想确定一下6 I |% `* {6 C' _. e
谢谢!
