This Unreal Engine 5.3 Gameplay Ability System video is about Chill Orbs at targets that come in range.
We start by updating the Orb Actor Blueprint to include Tracking a target Enemy. Next, we update the Chill Orbs Actor Blueprint to set the Orb’s target Enemy and cleanup the Orbs it tracks, as well as itself when no Orbs remain. We also add a Sphere Collision to choose Enemy Character Targets.
