Issue with PointLight Brightness

Help and Feedback Scripting Support
#1

Does anyone know what is the issue, when I click the button on UI it won’t change brightness of the PointLight in workspace. I’ve tried it in server script and in local script.

I have tried looking on DevHub but I haven’t find anything new.

Note: Code below is in a local script.

local MainFrame = script.Parent
local PlayClapMusicButton = MainFrame.Clap
local CloseCurtainsButton = MainFrame.Close_Curtains
local OpenCurtainsButton = MainFrame.Open_Curtains
local PlayEndingMusicButton = MainFrame.Ending_Music
local ExitButton = MainFrame.Exit
local PlayIntermissionMusic = MainFrame.Intermission
local LightsOnButton = MainFrame.Lights_On
local LightsOffButton = MainFrame.Lights_Off
local CinemaAudio = game.Workspace.cinemaarea
local StageLight = game.Workspace.stagelight.PointLight

local LightsOn = false
local CurtainsOpen = false

function TurnLightsOn()
	while wait(0.1) do 
		StageLight.Brightness = StageLight.Brightness + 0.1
		if StageLight.Brightness == 3 then
			break
		end
	end
end

function TurnLightsOff()
	while wait(0.1) do 
		StageLight.Brightness = StageLight.Brightness - 0.1
		if StageLight.Brightness == 0 then
			break
		end
	end
end

PlayClapMusicButton.MouseButton1Click:Connect(function()
	CinemaAudio.SoundId = ""
	CinemaAudio:Play()
end)

PlayIntermissionMusic.MouseButton1Click:Connect(function()
	CinemaAudio.SoundId = ""
	CinemaAudio:Play()
end)

PlayEndingMusicButton.MouseButton1Click:Connect(function()
	CinemaAudio.SoundId = ""
	CinemaAudio:Play()
end)

ExitButton.MouseButton1Click:Connect(function()
	MainFrame:Destroy()
end)

LightsOnButton.MouseButton1Click:Connect(function()
	TurnLightsOn()
end)

LightsOffButton.MouseButton1Click:Connect(function()
	TurnLightsOff()
end)

If you have a solution or an idea I would love to hear it.

i am a bit confused on how that would work.
I have never seen someone do that so i don’t know if it is a normal thing but i just have no idea how that would work

#3

What do you exactly mean by that? Should wait be inside the loop? Like this;

while true do
wait(0.1)
end
#4

when you do while you need to give it a true statement for it to loop so if you pass in something that is false or nil it won’t loop so doing wait(0.1) there would give it a nil so it wouldn’t do anything

#5

Have you tried using debounce or toggle variable?

--Similar to this:
local isOpen = false

local function OpenLights()
    if isOpen == false then
         isOpen = true

        Lightbulb.PointLight.Enable = true
    end
end

local function OpenLights()
    if isOpen == true then
         isOpen = false

        Lightbulb.PointLight.Enable = true
    end
end

In this case for me, I’d rather use TweenService for better fade effect

Yes, that was exactly what I was trying to do but I don’t know how that Tween would work, could you show me an example?

#8

also i would recommend if you did

while StageLight.Brightness > 0 do
      -- also when dealing with while loops always remember to add a wait() in it or the game will crash
      -- decrease brightness
end

Sure, I’ll try it. Thanks for letting me know.

#10 
local TweenService = game:GetService("TweenService")

local FadeInfo = TweenInfo.new(1, Enum.EasingStyle.Sine, Enum.EasingDirection.Out, 0, false, 0)


local isOpen = false
local function OpenLights()
    if isOpen == false then
        TweenService:Create(Lightbulb.PointLight, FadeInfo, {Brightness = 3}):Play()
        isOpen = true
    end
end

local function CloseLights()
    if isOpen == true then
        TweenService:Create(Lightbulb.PointLight, FadeInfo, {Brightness = 1}):Play()
        isOpen = false
    end
end

Edit: I forgot to add Interval for the TweenInfo

--I added a 1 in the TweenInfo.new(1, ~~~)

Should I implement RemoteEvent or would I put this in local or server script?

If you are going to show the fade of the light in all players use Remote events but if not use my recommended script

Yeah, I’m trying so everyone can see it cause it’s for a theatre.

here slowly makes it brighter and brighter and brighter probably “if StageLight.Brightness == 3 then” this area is not working
edit : it makes it stop in 3 but probably it needs to be changed or script’s that stage is not working
