This is an experimental technology
Because this technology's specification has not stabilized, check the compatibility table for usage in various browsers. Also note that the syntax and behavior of an experimental technology is subject to change in future versions of browsers as the specification changes.
The pulse() method of the GamepadHapticActuator interface makes the hardware pulse at a certain intensity for a specified duration.
Syntax
gamepadHapticActuatorInstance.pulse(value, duration).then(function(result) { ... });
Parameters
- value
- 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).
- duration
- 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.
