al_rumble_haptic(3) Library Functions Manual al_rumble_haptic(3) NAME al_rumble_haptic - Allegro 5 API SYNOPSIS #include <allegro5/allegro.h> bool al_rumble_haptic(ALLEGRO_HAPTIC *hap, double intensity, double duration, ALLEGRO_HAPTIC_EFFECT_ID *id) DESCRIPTION Uploads a simple rumble effect to the haptic device and starts playback immediately. The parameter intensity is a relative magnitude between 0.0 and 1.0 that determines the intensity of the rumble effect. The duration determines the duration of the effect in seconds. You must also pass in a pointer to a user allocated ALLEGRO_HAPTIC_EF- FECT_ID(3). It it is stored a reference to be used to control playback of the effect. Returns true if the rumble effect was successfully up- loaded and started, false if not. In case false is returned, the rumble effect will be automatically re- leased as if al_release_haptic_effect(3) had been called, so there is no need to call it again manually in this case. However, if true is returned, it is necessary to call al_release_haptic_effect(3) when the effect isn't needed anymore, to prevent the amount of available effects on the haptic device from running out. SINCE 5.1.8 [Unstable API]: Perhaps could be simplified due to limited sup- port for all the exposed features across all of the platforms. Awaiting feedback from users.
