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) @- \1 z' Z- N; t, Q3 r
其中有一段如下
% I1 N$ _( M4 n) r& xask turtles with [ infected? = true ]
( g+ }, Y" j) |) j4 S我原本以为这句会回传『所有』infected? = true 的 turtle, o$ ]% ^; A8 c$ C( }
但看结果似乎不是这样。3 S* m, _! c. w9 G6 o% ^+ N
5 `9 f& J; t( Y( t; o
假设所有符合条件的有 5 笔
" I9 R4 E6 g- U! h有时候回传 1 笔,有时回传 3 笔,是不固定的
" f9 @, a" Y7 m* V9 }- U) D0 `回头查语法定义; x$ A, b% q8 U7 C
with , z" H) g. Z4 K* o M5 c
agentset with [reporter]
. l, M- W6 s( T3 D8 jTakes 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.: K$ r8 ^+ ]: K$ G+ h% Y
它只说回传 agents satisfying the given condition
5 z6 h2 f/ H3 I. K1 R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 ? ( q5 w' R5 u( q4 @7 _$ x" ^
L' x' _/ `6 p1 i) A. q
想确定一下
. \% e6 _8 [- E6 q谢谢!
