Hi everyone! I’m Mario and welcome to Code On Fire! 
In this tutorial, we level up your game development skills by building a completely modular, decoupled, and Data-Driven Health & Damage System in Unreal Engine 5.
This isn’t just a basic health bar tutorial. We are building a professional AAA-standard architecture that handles health, traps, enemy attacks, hitscan weapons (Line Traces), and even prevents Friendly Fire!
In this Masterclass, you will learn how to:
Use Primary Data Assets to store stats cleanly (Data-Driven design)
Create plug-and-play Actor Components for logic encapsulation
Master Blueprint Interfaces to decouple your damage system (Zero Casts!)
Fix “Friendly Fire” using Actor Tags
Handle Line Trace hit detection and fix Capsule Collision issues
Trigger physical Ragdolls on death
