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+ X) V. x: L2 k. {- e. t, N5 |4 `
其中有一段如下; H+ E2 ?- H/ `
ask turtles with [ infected? = true ]
$ ` r1 \; V6 d% A我原本以为这句会回传『所有』infected? = true 的 turtle4 \, u- w) F0 a& |6 N# \+ z# a
但看结果似乎不是这样。
& o' P- z! d( T, [ r& f+ R1 j* m* }' h8 I" R4 Q
假设所有符合条件的有 5 笔
9 I: [1 l6 ]+ A. @6 o有时候回传 1 笔,有时回传 3 笔,是不固定的
4 G, C; c N( b) G( y9 u! i回头查语法定义' M( t. f5 j1 L6 |+ p' V. u
with
3 z" K5 S$ h5 q, nagentset with [reporter]
: v9 G/ x! u* ?& u9 o0 iTakes 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.
6 D5 w: }/ |6 }2 i$ |) }它只说回传 agents satisfying the given condition
/ i+ D4 ^. u S. j* s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 ?

想确定一下6 P2 N) Q- j% f5 A9 S% v2 ]/ ~
谢谢!
