我的程序如下：% u, b6 p2 i2 `
breed [dogs dog]
- `* P$ k3 m! {breed [cats cat]7 z/ Y9 H6 G' K9 }# F1 E
breed [cows cow]4 \, X0 ~; V1 ?8 V' z0 t3 G* W! z
8 t6 I% w- Z2 {8 X: A% C8 ito setup
8 ?1 T2 h* r! S clear-all g1 N7 P; i$ j5 p1 e2 _
set-default-shape dogs "dog", C. T. P: d) H+ Q# b ^' @' U, X: F
set-default-shape cats "cat"" t; v% A/ A. b; s6 O$ l, G5 u* c" R
set-default-shape cows "cow"
. m+ @3 P' E8 v ask patch 0 1 [ sprout-dogs 1 ]

1 q3 L7 z8 V6 A( v- rend' ?( h9 P% Q3 P- E K

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：2 O1 K1 z, B3 l3 b0 z! ?8 }7 `# s
error while observer running SET-DEFAULT-SHAPE in procedure SETUP
1 K9 [' t& V: w# g$ q# s$ ~ r3 ~9 `"dog" is not a currently defined turtle shape" g/ W5 g, e: O# I9 [. E

5 p6 {4 I3 @8 O5 ] G我用的版本是4.0.4 请大虾们指教下。thanks！ |
