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. L! @' ^) D. q/ [, j. Y
其中有一段如下" u2 y! V# A+ G9 _+ C$ `
ask turtles with [ infected? = true ] * H& C; w/ T. ?
我原本以为这句会回传『所有』infected? = true 的 turtle, n/ E- s; u* Z9 ]- @- V, [3 |
但看结果似乎不是这样。3 I- S. D# O; h: I) L" v
, U& c6 p% r& ?$ K+ W9 d
假设所有符合条件的有 5 笔
& a9 c, j8 Z0 i& N有时候回传 1 笔,有时回传 3 笔,是不固定的
( C$ J3 L6 q% r8 K! A" A回头查语法定义
( _6 \" B5 r& `' |6 wwith ) D! U% w$ i2 J% P! N& X
agentset with [reporter]: _* T( L5 y7 k7 M4 K* A
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.
" ?4 E% n8 e, |% W它只说回传 agents satisfying the given condition
* b/ D9 f! y- R' ?( t% T' X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 ? : s$ \# y0 R. t6 c
# J; K: W( |$ t8 s想确定一下
+ R) U3 S, z+ P1 ?谢谢!
