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! {% N; ~4 O z
其中有一段如下
' \- V6 Z. s J2 S/ a4 r3 Task turtles with [ infected? = true ]
. Y/ ?: m% I4 u0 i我原本以为这句会回传『所有』infected? = true 的 turtle
# k/ u( D5 B0 p. D* m z+ d2 G5 w2 n2 ^但看结果似乎不是这样。
/ z7 `3 F, |, k2 }' G) p) ^9 d# A7 J" V" H h$ K. O+ b
假设所有符合条件的有 5 笔: p+ B, R Z5 O: h4 w4 R; p
有时候回传 1 笔,有时回传 3 笔,是不固定的
1 \! [* `7 ?0 a: ]$ R回头查语法定义, b h5 _: y' U" M- i
with ( B7 d5 T7 c* R z3 D
agentset with [reporter]$ K/ Y. [! j; m
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.
& S8 y2 @7 u" O它只说回传 agents satisfying the given condition
# D! \: S6 x* C3 z7 T W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 ? % v$ d. J0 w T& Q
N4 b/ O3 V! D, E# B想确定一下1 S5 Q( X% w$ M/ s9 M' m! X
谢谢!3 ?" ?9 T8 _# A* Z+ J: C
