How to make an NPC be able to detect you if your seen by them?
Basically Notoriety. Check out that game btw. When NPC look at you that detect you, but if you behind a wall, they don't detect players.
I tried making a hat for the NPCs that will touch a player if he/she is in the NPCs sight. But it goes through walls so that doesn't work.
Please help me. I have no idea what to do, iv been thinking about this for more than a year.

you can use camera.GetPartsObscuringTarget()

So I tried NPC.Humanoid.Camera but it doesn't exist, how do use this information you gave me to make the NPC see other players? AlexanderYar 788 — 5y

you need to insert a camera object in the NPC, then set the camera subject property to the humanoid of the NPC, and i am sure that should work.. User#23252 26 — 5y

here is a useful link: https://developer.roblox.com/en-us/api-reference/property/Humanoid/CameraOffset User#23252 26 — 5y

also btw, the reason why you can't access Humanoid.Camera is b/c it's not a property field of a Humanoid: here is a list of all properties of a humanoid: https://developer.roblox.com/en-us/api-reference/class/Humanoid User#23252 26 — 5y

You can raycast from the NPC's head to the target, if it hits a body part belonging to them, then the NPC sees them.
1 | local maximumDistance = 300 -- the ray's max distance, in studs |
2 | local ray = Ray.new(NPC.Head.Position, (TARGET.HumanoidRootPart.Position - NPC.Head.Position).Unit * maximumDistance) |
3 | local hit = workspace:FindPartOnRayWithIgnoreList(ray,{NPC}) |
4 |
5 | if hit.Parent == target.Parent then |
6 | print("i can see the player") |
7 | else |
8 | print("i cannot see the player") |
9 | end |
Keep in mind that I haven't tested the code above, so it may need some tweaking.

Yes thank you, but although it does that, wouldn't a part raycast through itself.because if you make the raycast start at the heads position, that is inside the head, so wouldn't it also detect a player behind the NPC?also, would the Ray go through invisible or not collide parts??

No it wouldn't go through invisible or non-collideable parts, you can use the CollectionService to add tags to the parts which you want the ray to ignore, then simply add it to the IgnoreList table. strongrussianboy123 68 — 5y
