Hello,
I tried to make a health bar, by following the steps in this Player Health & Armor - #3 Creating A First Person Shooter (FPS) With Unreal Engine 4 - YouTube , and this Regenerating Armor & Damage Function - #4 Creating A First Person Shooter (FPS) With Unreal Engine 4 - YouTube video (He uses an older version of UE4, but all the nodes that he uses are avaible on UE4.25.3). But at the end of all of this, i noticed that my health bar is not getting less.
here the screenshots:
