我的程序如下：3 s( j1 [" h+ b+ p
breed [dogs dog]
$ d+ i! @7 Y5 R9 T0 ^& |, Gbreed [cats cat]) V- l" @) ^8 ?
breed [cows cow]9 X0 D$ D6 i; t8 n: R
$ d0 b9 j) T; tto setup
- j* L1 W2 @% [" y8 ~4 S$ o clear-all) T( Q6 i5 P1 I
set-default-shape dogs "dog"' S: h( @8 z) @4 f7 j; U
set-default-shape cats "cat"& A; e- z1 |1 n; Z" z! }2 j
set-default-shape cows "cow"7 X9 [7 V. k) {1 q+ u# A
ask patch 0 1 [ sprout-dogs 1 ]
( ^7 v* h9 T3 C1 w2 H5 T2 O ask patch 0 0 [ sprout-cats 1 ] i: m* _: k' S. E3 H
ask patch 0 -1 [ sprout-cows 1 ]; r) A0 ?/ }/ A9 s
end, B* R$ J- m/ y
, C8 D3 b) w' ?/ r* O+ V% M
* Z" `, t$ A" M
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：$ `. u# Z4 L% U% f
error while observer running SET-DEFAULT-SHAPE in procedure SETUP
0 `$ _8 E& \. `# P"dog" is not a currently defined turtle shape
1 r2 v6 j+ n4 C* S9 c(halted running of setup): @! X4 g3 K! t f
+ Q" `$ x1 F7 { B
( Y& l' k* N$ w) e& D我用的版本是4.0.4 请大虾们指教下。thanks！ |
