我的程序如下：7 R* Q5 x" y* f/ c9 o, s! h
breed [dogs dog]# j0 C2 X6 H9 s, @( t3 g# H- K
breed [cats cat]
, q `+ ~! Y6 K t$ g* Vbreed [cows cow]
z, h0 e0 s4 x# P8 y
' ~/ ]; o a. X( \2 a% E& eto setup+ ^$ q+ s2 D- |- W( z1 D
clear-all0 B8 ~8 k. }# ?: \7 k; d' |' I
set-default-shape dogs "dog") B0 a$ \ T: l0 c
set-default-shape cats "cat"
& S, O1 Z. y4 y/ _$ A1 t8 s5 T. j8 h set-default-shape cows "cow"
7 K S. v3 `! |9 w w" T. C ask patch 0 1 [ sprout-dogs 1 ]- r" `( n& j: f/ k
ask patch 0 0 [ sprout-cats 1 ]) j' p+ t7 R/ ]6 O( I( `+ x
ask patch 0 -1 [ sprout-cows 1 ]" ^2 Q) V h: e3 ~5 [8 P3 }% { l2 n
end
4 M! M4 P4 D- l4 B- A$ S) T1 b$ L& y; S, d- y, w, e8 Z0 I
) Q R( I {* T6 F. o' e: D; N
这个是netlogo自带模型库里的模型中的程序，我新建文件再将其输入却提示错误：! M! s* O5 L4 x A1 i
error while observer running SET-DEFAULT-SHAPE in procedure SETUP
) e+ Z3 @" y3 @2 F, o1 ?"dog" is not a currently defined turtle shape! c) s6 m' C2 D" B. `* N* [! f2 }; F
(halted running of setup)
5 D3 N. W# a- j" {$ [& z. w+ @& i$ J C5 q) r1 x6 [) n
0 R7 `' h0 z/ D7 Q我用的版本是4.0.4 请大虾们指教下。thanks！ |
