Help with HUD

I recently started this game, and I was wondering how to add a health meter (3 hearts that disappear when taking damage/touching enemy). Can anyone help?

It seems to me that examples and tutorials on lives/health systems were already discussed so if you search in the forum you can find more
However have a look at this fast project
comments in code should be sufficient
