setGain method

bool setGain(
  1. int gain
)

Set the global gain of the specified haptic device.

Device must support the SDL_HAPTIC_GAIN feature.

The user may specify the maximum gain by setting the environment variable SDL_HAPTIC_GAIN_MAX which should be between 0 and 100. All calls to SDL_SetHapticGain() will scale linearly using SDL_HAPTIC_GAIN_MAX as the maximum.

\param haptic the SDL_Haptic device to set the gain on. \param gain value to set the gain to, should be between 0 and 100 (0 - 100). \returns true on success or false on failure; call SDL_GetError() for more information.

\since This function is available since SDL 3.2.0.
