我的程序如下：- c% ^ V" X9 V! }$ y
breed [dogs dog]; p' A' Z, }1 `; s4 q6 j m* v: ?
breed [cats cat]. [* Z2 S) z! o3 X
breed [cows cow]/ W6 S, ~6 s4 h. ] k9 Q: k1 R- F
1 t4 s/ ^# @( Q7 w
to setup
0 O1 o: j8 m8 W9 j W& p clear-all
/ i( D$ u# {6 o set-default-shape dogs "dog"
3 T. H+ F2 M0 f, @6 Y set-default-shape cats "cat" F. ^. z* S7 R+ a9 |: X( c
set-default-shape cows "cow"
0 u9 k; z6 P! R. {8 H ask patch 0 1 [ sprout-dogs 1 ]
7 q: d; s) B+ c' [% ?- J G' f ask patch 0 0 [ sprout-cats 1 ]1 Y }9 i6 T- Q

, Z* e( C* X4 S0 P' i6 hend" A! {0 M- O+ ^. Z2 s6 N
: |9 z* I) L" J. _* r/ T, ~* v- W! S
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 {, R( @% f* [& Y9 b6 Y8 Serror while observer running SET-DEFAULT-SHAPE in procedure SETUP
+ I! v2 X9 i5 y. y; Q0 I9 i. r, f"dog" is not a currently defined turtle shape

/ E8 N0 @8 |% Q1 T8 Y, f# c
" S5 P, m8 n" a: G& G' b1 H, f3 Q) d! l" J! W
我用的版本是4.0.4 请大虾们指教下。thanks！ |
