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0 L U3 H: h( n0 {
其中有一段如下
7 V/ p$ Y" g+ F' o& G1 Y! n# G- yask turtles with [ infected? = true ]
. _7 J* ^8 s# N2 K我原本以为这句会回传『所有』infected? = true 的 turtle
& ?, l8 K& E+ W$ X但看结果似乎不是这样。8 r% F% C5 p) D2 p1 j7 m
( S: S4 b4 K! G4 b+ \6 l假设所有符合条件的有 5 笔7 o' Z6 |3 O3 Q
有时候回传 1 笔,有时回传 3 笔,是不固定的& E' h8 y; B, a6 P
回头查语法定义
# l' _+ y- P- T. uwith 7 m% Y- g9 ~* v+ g8 ^
agentset with [reporter]6 x: u( L9 V Q5 k# M
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.2 @: X1 v( z/ Z8 d
它只说回传 agents satisfying the given condition
) r$ B/ @# d r8 j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 ? 5 P, O/ o5 Q7 ^) ?
; g$ j& g, G' i& w+ h% T' q
想确定一下+ a! Z1 g, |$ z3 T$ ]: C" H* a: J
谢谢!
