This Unreal Engine 5.4 video is about building the Cannon Tower, which will have a lower fire rate, but apply damage to an Area, in a future video.
We start by creating the Cannon Projectile and Weapon, with their respective meshes. Next, we create the Cannon Attributes Gameplay Effect, which compared to the Turret Attributes, will have a longer delay between firing, and do half the damage, but later, apply to an area. Lastly, we create the Cannon Tower, attach the Cannon Weapon, and ensure it’s being created from the UI action, with a minor refactor.
