Question❓ in UNITY 3D / 2D

Hey Unity People
Anyone know how to make a usage timer which will have a bar which goes down when using an ability and goes up when you don't?
I need this for a game and really hope I can get an answer.
(I can't find good tutorials)
What do you guys think about customizations in shoot em ups? what is considered great customization?
