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, N& B3 Y! Z1 @6 `
其中有一段如下
( M: }- {5 ~) Y% @# Sask turtles with [ infected? = true ]
5 `5 A% ]2 y) v; X我原本以为这句会回传『所有』infected? = true 的 turtle& r/ {1 s, h) q3 ]
但看结果似乎不是这样。
5 y; ~4 {# E# e X% X X7 ?% b% {3 j% m2 \7 F2 c
假设所有符合条件的有 5 笔
- d" `0 S `. D: C( |9 w; ?$ I2 D8 x有时候回传 1 笔,有时回传 3 笔,是不固定的
# K4 \) c% r! P* B回头查语法定义
8 M0 J: F+ W4 ^( M, [3 l* twith w1 ^" Y: c( H! n0 Q
agentset with [reporter]
( L& v6 I/ d, `. T+ U+ P W5 |7 @! [' ZTakes 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.: \$ A9 n- K( Z2 G+ ^4 c& G
它只说回传 agents satisfying the given condition
# P( P( H- {5 e. i* s% X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 ? 2 I) C0 ~1 K/ j! { d& ]0 @7 x
4 c; s" L) ?% z p$ i/ g
想确定一下% e: |% [* |1 q4 [
谢谢!
