我的程序如下：
& @( ?# B Z6 ^1 k7 gbreed [dogs dog]5 y6 f3 m- k9 a: }
breed [cats cat]
" g5 t' h/ u( t8 L- |6 D8 rbreed [cows cow]9 r& X6 \9 s: G, U+ u8 g% T2 s
! `! Y: `1 i! D
to setup4 d! m* {7 J1 |5 O5 F, V( w+ G5 Q
clear-all% B6 X% t: i( B {- g6 h8 t
set-default-shape dogs "dog"/ i8 q. r( P j) A/ t
set-default-shape cats "cat"0 [4 {. x% @" h6 [+ Y
set-default-shape cows "cow"
7 {4 ]4 w5 J7 f* J: @! u5 B3 f ask patch 0 1 [ sprout-dogs 1 ]
X1 E4 X9 q! N; w+ T. q3 y ask patch 0 0 [ sprout-cats 1 ]
' c) e) u/ E; b" i1 m v ask patch 0 -1 [ sprout-cows 1 ]

6 I/ a1 T% f8 ~6 C# }5 [5 i3 X; X6 {( G: G! o0 C# l
+ y2 f2 Y. a2 }# K( z# S6 v
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：% @3 m+ Y5 J/ Y1 P" } l7 s: S3 _- q
error while observer running SET-DEFAULT-SHAPE in procedure SETUP
: R6 q' U& j$ k& r1 q7 c"dog" is not a currently defined turtle shape

/ m' g) J" `" [
: ~ K/ n; P, O y我用的版本是4.0.4 请大虾们指教下。thanks！ |
