al_get_haptic_gain3alleg5
Allegro 5 api
Usage
-
#include <allegro5/allegro.h> double al_get_haptic_gain(ALLEGRO_HAPTIC *hap)
Overview
Returns the current gain of the device. Gain is much like volume for sound, it is as if every effect’s intensity is multiplied by it. Gain is a value between 0.0 and 1.0. Only works correctly if al_get_haptic_capabilities(3alleg5) returns a value that has ALLEGRO_HAPTIC_GAIN(3alleg5)ALLEGRO_HAPTIC_CONSTANTS(3alleg5) set. If this is not set, this function will simply return 1.0 and all effects will be played without any gain influence.
Since
5.1.8
[Unstable API]: Perhaps could be simplified due to limited support for all the exposed features across all of the platforms. Awaiting feedback from users.
