the gamepad to vibrate.
the intensity of the left trigger rumble motor, from 0 to 0xFFFF.
the intensity of the right trigger rumble motor, from 0 to 0xFFFF.
the duration of the rumble effect, in milliseconds.
true on success or false on failure; call SDL_GetError() for more information.
Start a rumble effect in the gamepad's triggers.
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.
