[Extensions] make pulse() more like navigator.vibrate

[GrosSacASac]

It would be nice to have pulse be like navigator.vibrate or to have something similar

navigator.vibrate(100) // simple value for duration
navigator.vibrate([100,500, 100]) // array for duration, pause duration patterns

Thoughts ?

I think this is insufficient for the types of vibration effects that are common on gamepads. For instance, most modern gamepads support vibrating at varying intensity levels rather than simple on/off durations as used by navigator.vibrate.

I've proposed an alternate extension for vibration effects, please take a look:

#19 (comment)

It's used like this:

let pads = navigator.getGamepads();
pads[0].vibrationActuator.playEffect("dual-rumble", {
    startDelay: 0,
    duration: 1000,
    weakMagnitude: 0.5,
    strongMagnitude: 0.5
});

playEffect returns a Promise that resolves once the effect playback is complete. You can take advantage of this to simulate the on/off durations used by navigator.vibrate:

let startEffect = { duration: 100, weakMagnitude: 1.0 };
let continueEffect = { startDelay: 500, duration: 100, weakMagnitude: 1.0 };
pads[0].vibrationActuator.playEffect("dual-rumble", startEffect).then(() => {
    pads[0].vibrationActuator.playEffect("dual-rumble", continueEffect)
});
