[Help]Using Physfs for DataFiles

variancegears

Hi,

I am using allegro5 and am trying to implement Physfs for datafiles but I do not know where to start or how to initiate it. Is there a basic snippet of code for reference anywhere on this? I am trying to use it on some .wav files and what not but have no idea where to start. thanks

Before interacting with your "datafile" (which is just a ZIP file containing your files), you'll need to set up PhysFS and Allegro's PhysFS file interface.

#SelectExpand
  1#include <allegro5/allegro_physfs.h>
  2#include <physfs.h>
  3
  4...
  5
  6/* you'll have to get argv[0] from main to this call somehow */
  7if(PHYSFS_init(argv[0]))
  8{
  9  if(PHYSFS_addToSearchPath("datatile.zip", 1)
 10  {
 11    /* remember old file interface */
 12    al_store_state(&old_state, ALLEGRO_STATE_NEW_FILE_INTERFACE);
 13    al_set_physfs_file_interface();
 14    mysample = al_load_sample("sample.wav");
 15    ...
 16    /* restore old file interface when we are done accessing our datafile */
 17    al_restore_state(&old_state);
 18  }
 19}
