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 h7 V3 M; g9 c9 x7 C- }其中有一段如下
0 Z2 x, @0 q6 {9 {8 J* jask turtles with [ infected? = true ] 7 D; n0 I6 p4 Y& D/ b. _
我原本以为这句会回传『所有』infected? = true 的 turtle/ F4 E, r& l2 }+ I; R
但看结果似乎不是这样。+ l/ B r: s2 F# ^3 H2 p
( Y7 H" k7 D! ?
假设所有符合条件的有 5 笔1 B5 n+ P% x5 U7 \2 S: i8 r
有时候回传 1 笔,有时回传 3 笔,是不固定的
& `6 r! f1 |& R# w5 n回头查语法定义9 d- G' I+ U( t* c# W8 b0 U9 {
with
, k6 N% [, j7 |agentset with [reporter]9 z! C; M4 h) R6 T! X
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.' o* D7 l% \- s) w
它只说回传 agents satisfying the given condition3 e7 ~$ ]* t3 E. I2 ~
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 ?
