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
3 f1 @5 Y3 c* C5 ^4 P7 ?% d5 x其中有一段如下
4 o8 D+ U4 c. Y. N Aask turtles with [ infected? = true ]
- p7 N+ j6 I _% e8 ~# c我原本以为这句会回传『所有』infected? = true 的 turtle
3 p. d3 t, y- I1 b2 S* h3 S$ u- x. \但看结果似乎不是这样。1 N0 _" r: S4 u9 r
8 R; \8 V# j" g0 q7 R7 Y
假设所有符合条件的有 5 笔
/ a1 @& y. B T9 f) x, t+ ~有时候回传 1 笔,有时回传 3 笔,是不固定的
& ^- ^. s& ~3 ?回头查语法定义
$ J% U9 G7 a5 o/ m2 ~* k* W' V# Qwith
( V9 p; d5 q/ n3 D/ E7 J) dagentset with [reporter]
4 K3 d ~! C8 ~, O: c; HTakes 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.9 s. b. ?7 S4 Q
它只说回传 agents satisfying the given condition
, h; K6 O% J8 p6 d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 O1 I& U) s) n' y# C7 P; b6 p! Z
5 k- v* l( M |5 P想确定一下
