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* @" J8 p2 T% D- \( z$ v
其中有一段如下7 W, j# k8 N! Q' ~# `7 x
ask turtles with [ infected? = true ]
1 J& A8 x3 W$ M- M# n我原本以为这句会回传『所有』infected? = true 的 turtle" ?7 u0 k( R7 K7 D7 P3 c: j
但看结果似乎不是这样。' q( P" k' p8 Q! p4 t; c; c+ {" \6 c
& v _# s7 o: f" x" X, f假设所有符合条件的有 5 笔
! N: A/ e4 r6 h3 T4 P. I+ O" J有时候回传 1 笔,有时回传 3 笔,是不固定的; f( `0 k. Z% [# D1 B3 C; U
回头查语法定义% H) |, o9 u- h) x2 L& }
with 2 o% j0 j. h+ ~7 v! j5 Q+ X
agentset with [reporter]" ]! s( s, f) _: k9 ]4 z
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.& W; Z# V# C& x1 r8 [3 O! u, \
它只说回传 agents satisfying the given condition1 p( c& e& O4 c! P# {; k* G; M) k, G
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 ? 9 K% e; c& V, q. G4 h$ H& c
