Hey 
I’m currently creating my game “Nightfall: Find Your Way” and I want to replicate this type of smooth combat attack (video attached click here watch at 0:30, credit: Project: Unknown).
Can someone give me tutorial how to achieve this in Unreal Engine 5? 
Hello @VADS1452 ,Welcome back to the forums!
If you’re aiming to build a smooth and scalable combat system, I strongly recommend using the Gameplay Ability System (GAS), especially if you plan to support multiple abilities, cooldowns, and more advanced combat logic.
However, when it comes to the “feel” of smooth combat, most of it comes from how you set up your animations: using Animation Montages, proper blending, Anim Notifies for timing, and an input buffering system for responsiveness. GAS helps structure abilities, but the smoothness itself is mainly driven by animation and timing systems.
So I’ll leave you with these videos and the learning site where they explain all of this in more detail, which could help you achieve that type of smooth combat attack.
