Hi,
I’ve recently been following [this tutorial][1] on the official Unreal YouTube channel in order to create some basic AI for my game, however, I’ve run into an odd problem that’s halted my plans in their tracks. For whatever reason, the OnPerceptionUpdated event isn’t firing at all and has a note stating “No value will be returned by reference. Parameter ‘UpdatedActors’. Node: OnPerceptionUpdated”
I’m not sure whether this is a bug with version 4.10.2 of the Unreal Engine or if I’ve just messed things up, but I’m honestly at a loss as to what I can do to resolve the problem so any help would be appreciated. Attached below is an image of my AI controller setup.
