bool al_play_haptic_effect(ALLEGRO_HAPTIC_EFFECT_ID *id, int loop)
Plays back a previously uploaded haptic effect. The play_id must be a valid ALLEGRO_HAPTIC_EFFECT_ID(3alleg5) obtained from al_upload_haptic_effect(3alleg5), al_upload_and_play_haptic_effect(3alleg5) or al_rumble_haptic(3alleg5).
The haptic effect will be played back loop times in sequence. If loop is less than or equal to 1, then the effect will be played once only.
This function returns immediately and doesn't wait for the playback to finish. It returns true if the playback was started sucessfully or false if not.
