SDL_RumbleJoystick

Start a rumble effect.

Header File

Defined in <SDL3/SDL_joystick.h>

Syntax

int SDL_RumbleJoystick(SDL_Joystick *joystick, Uint16 low_frequency_rumble, Uint16 high_frequency_rumble, Uint32 duration_ms);

Function Parameters

joystick	The joystick to vibrate
low_frequency_rumble	The intensity of the low frequency (left) rumble motor, from 0 to 0xFFFF
high_frequency_rumble	The intensity of the high frequency (right) rumble motor, from 0 to 0xFFFF
duration_ms	The duration of the rumble effect, in milliseconds

Return Value

Returns 0, or -1 if rumble isn't supported on this joystick

Remarks

Each call to this function cancels any previous rumble effect, and calling it with 0 intensity stops any rumbling.

This function requires you to process SDL events or call SDL_UpdateJoysticks() to update rumble state.

Version

This function is available since SDL 3.0.0.
