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9 C x+ {" C4 r% ?
其中有一段如下6 h' D# i. q$ V5 L
ask turtles with [ infected? = true ] 1 }4 J" _" j) U( ^, I
我原本以为这句会回传『所有』infected? = true 的 turtle
* ?* i1 C- ^; G1 y' U) h% x' ~但看结果似乎不是这样。
" |& |2 F- `; H! Y( w9 l+ t( C
c0 @8 A; H6 j: g$ H假设所有符合条件的有 5 笔( G2 f/ Q0 {1 L
有时候回传 1 笔,有时回传 3 笔,是不固定的
4 U4 }8 ^; v) Z回头查语法定义( d u; v9 X+ V
with 6 q8 e5 z( M) s* L3 V' k
agentset with [reporter]
$ ?2 x, {- C8 q$ eTakes 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.; v# I6 t, b# ~
它只说回传 agents satisfying the given condition8 x: ^6 S! D6 q$ F
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 ?
- u r* K4 q6 P7 t9 A( C8 y0 j" x7 P( f+ u
想确定一下% T+ i% i1 r! Q
谢谢!8 L* W5 u$ p8 E+ J4 M
