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+ m8 _8 ~; n# I
其中有一段如下
) p, ?1 ~: E$ Q2 I2 t4 bask turtles with [ infected? = true ]
) o5 ?8 F R2 |- R; k8 k2 B我原本以为这句会回传『所有』infected? = true 的 turtle
2 g1 c! S7 q3 w+ _* Q- y% y但看结果似乎不是这样。, R5 Z( i2 d% D+ @, x, B0 z
9 i' @( {# I0 L9 c) [3 ~" ]
假设所有符合条件的有 5 笔2 Z) \' L( `& u& ?/ m# k% n
有时候回传 1 笔,有时回传 3 笔,是不固定的
6 d( v: d8 P( W" S回头查语法定义
" j" n& y' v1 {. n8 e& nwith
6 `3 F3 m- O, d& nagentset with [reporter]) g+ r9 R, u0 g* M/ U* g
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.7 K+ k9 P% }1 x
它只说回传 agents satisfying the given condition
0 q( _0 e. u Z4 f) I) 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 ? [ j" b$ y* m7 y* }! k
* f% [( o7 G( t/ `想确定一下
& Y( o$ s# O& M9 ?# G: q" {谢谢!
0 w( e5 g) I% T% x/ @ |
