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. X/ l+ X, Y& w- i, X' b3 {. X
其中有一段如下; \0 l$ {4 S5 \8 T: g7 X
ask turtles with [ infected? = true ]
' p0 K% f6 i9 o. v我原本以为这句会回传『所有』infected? = true 的 turtle
+ \5 ^6 n7 v- h$ e! ]( s8 f但看结果似乎不是这样。/ H' K) L: K, W/ m5 u6 v ~8 t% @

有时候回传 1 笔,有时回传 3 笔,是不固定的

agentset with [reporter]
1 d# S: e; M- g/ F5 WTakes 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.# V+ \ \0 G, Q: s. G7 X2 c8 C
它只说回传 agents satisfying the given condition
% D6 z4 v1 J5 ]2 `6 l7 }" 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 ? " Q3 ? [2 S' ~3 _9 Z; m' P

想确定一下
