PS4 controller works fine. Check the Input.start_joy_vibration(0, 1, 1, 1) function, if you want a rumble effect! ;)
As for the refill: put the refill code after the character landed and/or the animation is finished. If you want to animate the refill, you can use a Tween node.

Nice ! Good to know the engine also has built in features for rumble controllers, i'll see if i can add that whenever i solve some of the problems i have on the table for the next update.
Same with the Bar refill, i'll see how this works, i've seen some tutorials about the tween node but didn't quite understood how it works yet so i'll probably go for a few rewatches to learn that properly :p
