###### (This is the legacy documentation for stable SDL2, the current stable version; [SDL3](https://wiki.libsdl.org/SDL3/) is the current development version.) # SDL_JoystickRumbleTriggers Start a rumble effect in the joystick's triggers ## Header File Defined in [SDL_joystick.h](https://github.com/libsdl-org/SDL/blob/SDL2/include/SDL_joystick.h) ## Syntax ```c int SDL_JoystickRumbleTriggers(SDL_Joystick *joystick, Uint16 left_rumble, Uint16 right_rumble, Uint32 duration_ms); ``` ## Function Parameters | | | | -------------------- | ----------------------------------------------------------------- | | **joystick** | The joystick 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 0, or -1 if trigger rumble isn't supported on this joystick ## 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_JoystickRumble](SDL_JoystickRumble)() instead. ## Version This function is available since SDL 2.0.14. ## See Also * [SDL_JoystickHasRumbleTriggers](SDL_JoystickHasRumbleTriggers) ---- [CategoryAPI](CategoryAPI), [CategoryAPIFunction](CategoryAPIFunction)
