(Solved) How to detect if an object is facing the camera within a certain angle

[flipwon]

Hey guys,

I’ve been knocking my head off a wall trying to figure this out. I’m trying to get the angle of an object
looking at my camera to enable or disable a tooltip. Basically, if the angle is too great from the camera, I’d like the tooltip to disable.

I’m not sure how to describe the problem any better as english isn’t my first language. Here’s a terrible diagram:

So if looking at the side or back of the object, I set false. I’d love to show something that I have, but I have nothing but a boolean as of now as I’ve started over and over again.

Thanks in advance

It was actually pretty simple:

var angle = Vector3.Angle(MyDistanceGrabInteractor.gameObject.transform.TransformDirection(a), Camera.main.transform.TransformDirection(Vector3.forward));
