NAME
SDL_RumbleGamepadTriggers - Start a rumble effect in the gamepad's triggers.
HEADER FILE
Defined in SDL3/SDL_gamepad.h
SYNOPSIS
#include "SDL3/SDL.h" bool SDL_RumbleGamepadTriggers(SDL_Gamepad *gamepad, Uint16 left_rumble, Uint16 right_rumble, Uint32 duration_ms);
DESCRIPTION
Each call to this function cancels any previous trigger rumble effect, and calling it with 0 intensity stops any rumbling. Note that this is rumbling of the _triggers_ and not the gamepad as a whole. This is currently only supported on Xbox One gamepads. If you want the (more common) whole-gamepad rumble, use SDL_RumbleGamepad () instead. This function requires you to process SDL events or call SDL_UpdateJoysticks () to update rumble state.
FUNCTION PARAMETERS
gamepad the gamepad to vibrate. left_rumble the intensity of the left trigger rumble motor, from 0 to 0xFFFF. right_rumble the intensity of the right trigger rumble motor, from 0 to 0xFFFF. duration_ms the duration of the rumble effect, in milliseconds.
RETURN VALUE
Returns true on success or false on failure; call SDL_GetError () for more information.
AVAILABILITY
This function is available since SDL 3.2.0.
