我的程序如下：
- H* C _1 A" {# J# U0 c6 Ibreed [dogs dog]
7 F. S4 d% g$ H8 b# ]; A7 A/ R- ibreed [cats cat]
* K5 V0 O* {8 G9 j- Xbreed [cows cow]0 M' t ^2 q2 U# H/ d' ^
0 n5 I$ k$ [8 u$ Q2 T5 ^ g; t- h
to setup% B% l2 H1 i/ t
clear-all: v* k/ m% y7 R8 e4 a" Y8 T0 U
set-default-shape dogs "dog"
( z5 g# }& f2 E" u- J set-default-shape cats "cat"
! E- a; Z- r% `/ ^& i( Y set-default-shape cows "cow"1 e8 Y+ f" k6 v" _6 W
ask patch 0 1 [ sprout-dogs 1 ]
/ [2 x, y8 F6 y9 N ask patch 0 0 [ sprout-cats 1 ], u5 F+ x9 T% f2 I+ h. }; q
ask patch 0 -1 [ sprout-cows 1 ]
% [$ h2 m/ T+ C# z o7 ~/ \+ Send5 _; w/ o# v2 Z& ?( e" ^8 X9 t
" |' P Z" n: k
" b! k0 v/ j9 B7 ?; L6 U
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：% x* j& G" O$ y& E
error while observer running SET-DEFAULT-SHAPE in procedure SETUP
; ^$ |$ l8 P" |: i5 A# V"dog" is not a currently defined turtle shape
# ` i8 I; V, D$ K3 U(halted running of setup)
3 o( t- |0 [. w1 C) q: I' R! J% h( e( T
' M1 q2 P& V: |5 {% n$ g9 Y& V
我用的版本是4.0.4 请大虾们指教下。thanks！ |
