Ah, I see. This is where I’m stuck as well. I’m specifically interested in a way to trigger an event once the player leaves the outer ring of the AI’s vision. I suppose I could put in age checks, it just seems like there would be a cleaner way to do it.
Edit: found this https://answers.unrealengine.com/questions/249501/detect-when-ai-perception-loses-sight-of-the-playe.html
It helps with sight at least. Not sure about hearing yet.
