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
) ^' O. j; e) \$ b其中有一段如下+ m4 [" r1 N; a N" u( f$ s' s2 M
ask turtles with [ infected? = true ] / H! v4 m% j1 C6 m2 s( Y+ j+ G9 m
我原本以为这句会回传『所有』infected? = true 的 turtle
7 H3 N$ G, |( u" V; x但看结果似乎不是这样。* G. ~1 g: H. X7 Q
) y7 u; n! N; J) {假设所有符合条件的有 5 笔& e' i% C) ?0 B$ D
有时候回传 1 笔,有时回传 3 笔,是不固定的
1 N# ?" f; |1 h+ o8 R o. Q1 ^ @回头查语法定义
: n/ G' }, ]8 vwith " o3 V( i# d5 l6 x
agentset with [reporter]$ H0 i7 Z8 \9 |; U# p" r. o
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.1 R8 t: b2 K* B4 E" f3 I, \( y
它只说回传 agents satisfying the given condition
/ J$ J; E2 \) |9 `0 q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 ? ( |0 `! U9 ]. \9 j$ i. i
; ?3 l1 M5 H, A, V' j
想确定一下
