This Unreal Engine 5.4 video is about applying damage from the Weapon and Projectile to the Enemy Hit.
We start by giving a way for the Weapon Blueprint to Get the Range and Damage from the Tower. Next, we create a Turret Tower Attribute Gameplay Effect to ensure the correct Range, Fire Rate, and Damage. Next, we create a Blueprint Function Library Utility Function to Damage Enemy, and call that from the previous video’s On Hit Target Function.
