hello all, question about Allegro''s datafiles: is there a way to store char data in a datfile? Ex. map.txt listing 0,0,0,0,0,0,0,0,0,0,0,0,0,0,0, 0,0,0,0,0,0,0,0,0,0,0,0,0,0,0, 0,0,0,0,0,0,0,0,0,0,0,0,0,0,0, 0,0,0,0,0,0,0,0,0,0,0,0,0,0,0, 0,0,0,0,0,0,0,0,0,0,0,0,0,0,0, 0,0,0,0,0,0,0,0,0,0,0,0,0,0,0 end map.txt listing levels.dat listing 0 BINARY DATA map.txt MYMAP end levels.dat listing c++ source #include <allegro.h> DATAFILE * mydat; unsigned char * lvl1[25][19]; int main(void){ allegro_init(); install_keyboard(); mydat = load_datafile(".\\levels.dat"); lvl1 = mydat[0].dat; //error, cannot convert from void * to unsigned char* return 0; } how could i cast this correctly? thank you much!

Haven''t tested that out, but as far as I can remember, Allegro dat-entries always have to be cast...meaning that it might look like something like this:


#include <allegro.h>

DATAFILE * mydat;
unsigned char * my_entry;
int main(void){

allegro_init();
mydat = load_datafile(".\\levels.dat");

my_entry = (char *)mydat[0].dat;
//this should work
return 0;
}


But the problem is the following: you declared your map.txt in ASCII format, single entries seperated by ",". This doesn''t mean that the dat-entry will be split up in those so-called tokens!

You either have to make the map-format binary or write a parser for your ASCII-based files...

For further questions, feel free to contact me via ICQ!
