How to detect if a part is within your field of view (Line of Sight)? [UNSOLVED]

Do this:

First make a localscript and put it in StarterGui then put this code in the localscript

Code:

local Camera = game.Workspace.CurrentCamera
local FOV = Camera.FieldOfView -- Field Of View :: INFO - Field Of View goes by radius
local Player = game.Players.LocalPlayer
local Parts = {}

function Scan(Parent)
    for i, v in pairs(Parent:GetChildren()) do
        table.insert(v)
        if #v:GetChildren() > 0 then
            Scan(v)
        end
    end
end

Scan(Workspace)

function GetPart(Player)
    for i=1, #Parts do
        if (Player.Character.Torso.Position - Parts[i].Position).magnitude < FOV then
            return Parts[i]
        end
    end
end

game:GetService("RunService").RenderStepped:connect(function()
    local Part = GetPart(Player)
    print(Part.Name)
end)
