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
) y- U3 X& v4 L& R) o9 P2 p, L其中有一段如下
0 F3 d" P% x2 b' G0 S6 O& mask turtles with [ infected? = true ]
/ n% N8 o3 v. L, h( m& P# g( h我原本以为这句会回传『所有』infected? = true 的 turtle
5 [) |' A! }% X7 b3 _但看结果似乎不是这样。
G0 [; K4 G" I
" j% h" G7 X; {+ T! y% \& @, U假设所有符合条件的有 5 笔/ r9 D$ H, A# s$ w7 \0 Y
有时候回传 1 笔,有时回传 3 笔,是不固定的
8 Y2 _5 E7 }+ K; y回头查语法定义
/ x3 w9 \* E0 O4 P4 e. dwith . N% B* i H( `; K, f0 ]; a! A
agentset with [reporter]% U2 t5 U& W. W* _
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.3 @# I0 {7 z1 G) V* O* l, P
它只说回传 agents satisfying the given condition
0 Z. C( [; M* ? _8 g* E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 ? V! K4 V4 i, {9 s5 U/ C8 V1 \( G
# ]0 ?" t- z& d: N. w0 o
想确定一下" a, ^! O% X" a
谢谢! Z& c/ h8 n9 ~3 M: I
