How would I approach developing this life bar system

Godot Version



Alright so I am trying to develop a fighting game. I’ve seen some tutorials and have a general understanding of hitboxes and damage values. For my game, I am trying to develop a three hit system like in “Footsies” where, in order to win the round, the player needs to hit a three hit combo on all the targetboxes (high, mid and low). However since majority of damage values work with variables, how would I approach that for my specific case?

Here’s Visual Representation of what I am trying to do

I would also like to point out that after hitting the opponent on that one spot, that it would be active for at least 1 or 2 seconds before reseting.
