Gain is much like volume for sound, it is as if every effect\[aq]s intensity is multiplied by it. Gain is a value between 0.0 and 1.0. Returns true if set sucessfully, false if not. Only works if al_get_haptic_capabilities(3alleg5) returns a value that has ALLEGRO_HAPTIC_GAIN(3alleg5)ALLEGRO_HAPTIC_CONSTANTS(3alleg5) set. If not, this function returns false, and all effects will be played without any gain influence. .SH SINCE .PP 5.1.8 .RS .PP \f[I][Unstable API]:\f[] Perhaps could be simplified due to limited support for all the exposed features across all of the platforms. Awaiting feedback from users. .RE
