This Unreal 5.3 Gameplay Ability System video is about adding some basic enemy movement to the Enemy Player Character.
We start with creating the AI Controller Blueprint, and then not use it, followed by a well spaced Nav Mesh Bounds Volume. Next, we connect the AI Controller BP in the Enemy Character, and add some random movement. After showing the natural movement of the Enemy Character, we copy and update the Animation Blueprint to bypass Input required functionality.
