# al\_get\_haptic\_gain(3)

Allegro 5 API

## NAME

al\_get\_haptic\_gain - Allegro 5 API

## SYNOPSIS

-

  ```
  #include <allegro5/allegro.h>
  double al_get_haptic_gain(ALLEGRO_HAPTIC *hap)
  ```

## DESCRIPTION

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(3)](/al_get_haptic_capabilities/3.md) returns a value that has ALLEGRO\_HAPTIC\_GAIN(3)[ALLEGRO\_HAPTIC\_CONSTANTS(3)](/ALLEGRO_HAPTIC_CONSTANTS/3.md) set. If this is not set, this function will simply return 1.0 and all effects will be played without any gain influence.
