###### (This is the documentation for SDL3, which is the current stable version. [SDL2](https://wiki.libsdl.org/SDL2/) was the previous version!) # SDL_RumbleJoystickTriggers Start a rumble effect in the joystick's triggers. ## Header File Defined in [](https://github.com/libsdl-org/SDL/blob/main/include/SDL3/SDL_joystick.h) ## Syntax ```c bool SDL_RumbleJoystickTriggers(SDL_Joystick *joystick, Uint16 left_rumble, Uint16 right_rumble, Uint32 duration_ms); ``` ## Function Parameters | | | | | ------------------------------ | ---------------- | ------------------------------------------------------------------ | | [SDL_Joystick](SDL_Joystick) * | **joystick** | the joystick to vibrate. | | [Uint16](Uint16) | **left_rumble** | the intensity of the left trigger rumble motor, from 0 to 0xFFFF. | | [Uint16](Uint16) | **right_rumble** | the intensity of the right trigger rumble motor, from 0 to 0xFFFF. | | [Uint32](Uint32) | **duration_ms** | the duration of the rumble effect, in milliseconds. | ## Return Value (bool) Returns true on success or false on failure; call [SDL_GetError](SDL_GetError)() for more information. ## Remarks 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 game controller as a whole. This is currently only supported on Xbox One controllers. If you want the (more common) whole-controller rumble, use [SDL_RumbleJoystick](SDL_RumbleJoystick)() instead. This function requires you to process SDL events or call [SDL_UpdateJoysticks](SDL_UpdateJoysticks)() to update rumble state. ## Version This function is available since SDL 3.1.3. ## See Also - [SDL_RumbleJoystick](SDL_RumbleJoystick) ---- [CategoryAPI](CategoryAPI), [CategoryAPIFunction](CategoryAPIFunction), [CategoryJoystick](CategoryJoystick)
