my test code :
| 1 | #include <allegro.h> |
| 2 | int main(void) |
| 3 | { |
| 4 | DATAFILE* dfile; |
| 5 | BITMAP* backbuffer; |
| 6 | const char *name; |
| 7 | allegro_init(); |
| 8 | install_keyboard(); |
| 9 | set_color_depth(32); |
| 10 | set_gfx_mode(GFX_AUTODETECT_WINDOWED, 800, 600, 0, 0); |
| 11 | |
| 12 | backbuffer = create_bitmap(800, 600); |
| 13 | clear_to_color(backbuffer, makecol(0,0,0)); |
| 14 | |
| 15 | dfile = load_datafile("running.dat"); |
| 16 | if (!dfile) |
| 17 | { |
| 18 | allegro_message("Error loading datafile"); |
| 19 | exit(-1); |
| 20 | } |
| 21 | for (int i= 0; dfile<i>.type != DAT_END; i++) |
| 22 | { |
| 23 | name = get_datafile_property(dfile+i, DAT_NAME); |
| 24 | allegro_message("name: %s", name); |
| 25 | } |
| 26 | |
| 27 | readkey(); |
| 28 | unload_datafile(dfile); |
| 29 | return 0; |
| 30 | } |
| 31 | END_OF_MAIN() |
after I ran the programe, why did all objects's name is empty_string?
the contents of unning.dat:
<root>
[0] BMP 000_BMP
[2] BMP 001_BMP
[3] BMP 002_BMP
...
etc
int the grabber.exe , i found that every object include NAME property.
how can I get the their names in my program?
thnks a lot.
edit: nevermind. not thinking...
]]>I found that after i used another *dat file to test the program, the program ran normally.
The running.dat was modified by me and I imported something else into it,
maybe I had destroyed it which result in the program's abnormity.
