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()

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.
local maximumDistance = 300 -- the ray's max distance, in studs
local ray = Ray.new(NPC.Head.Position, (TARGET.HumanoidRootPart.Position - NPC.Head.Position).Unit * maximumDistance)
local hit = workspace:FindPartOnRayWithIgnoreList(ray,{NPC})
if hit.Parent == target.Parent then
print("i can see the player")
else
print("i cannot see the player")
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.

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?
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..
here is a useful link: https://developer.roblox.com/en-us/api-reference/property/Humanoid/CameraOffset
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
