DESCRIPTION
The attached file contains all the source code from my Projectiles tutorial https://youtu.be/hkQ9bEwpfV8
The "Combat Damage System" post contains a link to a full project file which includes the source code of this "AOE Tutorial" as well as the "Projectile System Tutorial". So you can download that instead and have a fully functioning UE5 Project.
You are welcome to use them in your game for any purpose.
