#include <allegro5/allegro_audio.h>
bool al_play_sample(ALLEGRO_SAMPLE *spl, float gain, float pan, float speed,
ALLEGRO_PLAYMODE loop, ALLEGRO_SAMPLE_ID *ret_id)
Plays a sample on one of the sample instances created by
al_reserve_samples(3). Returns true on success, false on failure. Playback
may fail because all the reserved sample instances are currently used.
Parameters:
- gain - relative volume at which the sample is played; 1.0 is normal.
- pan - 0.0 is centred, -1.0 is left, 1.0 is right, or
ALLEGRO_AUDIO_PAN_NONE.
- speed - relative speed at which the sample is played; 1.0 is normal.
- loop - ALLEGRO_PLAYMODE_ONCE, ALLEGRO_PLAYMODE_LOOP, or
ALLEGRO_PLAYMODE_BIDIR
- ret_id - if non-NULL the variable which this points to will be assigned an
id representing the sample being played. If al_play_sample(3) returns
false, then the contents of ret_id are invalid and
must not be used as argument to other functions.
