Script do detect if player is illuminated

#1

I tried to find a script to steal utilize in one of my games that would detect if the player is in a light source or not, well I didn’t find any good ones, so I made my own. It’s not perfect but it works for me and it might work for you, attached are the script, which is in StarterCharacterScripts and a demo video

(that link expires in a week so if it doesn’t work you know why)

local LLT = 0.1 -- Set this to 0 if you want it to detect all light even if its very faint

local RS = game:GetService("RunService")

local player = game.Players.LocalPlayer
local char = player.Character or player.CharacterAdded:Wait()
local RP = char:WaitForChild("HumanoidRootPart")

local Lights = {}

local rayParams = RaycastParams.new()
rayParams.FilterType = Enum.RaycastFilterType.Exclude
rayParams.FilterDescendantsInstances = {char}

for i, v in pairs(workspace:GetDescendants()) do
	if v:IsA("SpotLight") or v:IsA("PointLight") then
		table.insert(Lights, v)
	end
end

function getRangeBrightnessWeight(range, brighteness)
	local value = brighteness/range
	return value > LLT
