The pulse() method of the GamepadHapticActuator interface makes the hardware pulse at a certain intensity for a specified duration.


gamepadHapticActuatorInstance.pulse(value, duration).then(function(result) { ... });


A double representing the intensity of the pulse. This can vary depending on the hardware type, but generally takes a value between 0.0 (no intensity) and 1.0 (full intensity).
A double representing the duration of the pulse, in milliseconds.

Note: Repeated calls to pulse() override the previous calls if they are still ongoing.

Return value

A promise that resolves with a value of true when the pulse has successfully completed.
