you can add collision group too, here is the link https://create.roblox.com/docs/reference/engine/classes/PhysicsService

local function isLookingAt(cam: Camera, what: Instance): boolean
  -- local rayParams = RaycastParams.new()
  -- rayParams.CollisionGroup = "checkingPart"
  local rayOrigin = cam.Position
  local rayDirection = cam.CFrame.LookVector
  local raycastResult = workspace:Raycast(rayOrigin, rayDirection, --[[ rayParams ]])

  if (not raycastResult) then
    return false
  end
  return raycastResult.Instance == what
end

maybe something like this could work (no guarantee)

Raycasting | Documentation - Roblox Creator Hub

Raycasting allows you to detect collisions and determine the position of objects.

PhysicsService | Documentation - Roblox Creator Hub

Class.PhysicsService primarily contains methods for working with collision
groups which define whether a set of parts may or may not collide with parts
in other collision groups. You can register a collision group through
Class.PhysicsService:RegisterCollisionGroup()|RegisterCollisionGroup() and
assign parts to it by setting those parts'...

thats what i came up with

#

is it supposed to be local or
