That’s the fun part, when your camera is your pawn you need to send orders down the line to those you control, but you cannot possess them otherwise you lose control of the camera pawn.
With MOBAs you control 1 character, so they can be a child of your controller here just fine. Basically you’d have a BP pawn with a root, and this camera setup as a child of it. Then you would have the selected character also be a child of the root. This way, nothing moves with each other in a parent/child scenario, and you can handle all of your character logic with you. You can even do this modularly if you were to attach the character’s after the fact kind of how the FPS template adds and sends commands to the guns.
