Help with server-side flashlight

Help and Feedback Scripting Support
#1

Hi, i’m trying to make a server side flashlight but can’t seem to figure it out, i haven’t worked with remote events that much before so it all seems a little complicated to me.

I made a flashlight but it’s only client-side.

The code:

local RS = game:GetService("ReplicatedStorage")
local RunService = game:GetService("RunService")
local TS = game:GetService("TweenService")

local TI = TweenInfo.new(.1, Enum.EasingStyle.Sine)

local cam = workspace.CurrentCamera

local plr = game:GetService("Players").LocalPlayer
local char = plr.Character or plr.CharacterAdded:Wait()

local mouse = plr:GetMouse()

local tool = script.Parent

local batteryLevel = char:WaitForChild("BatteryLevel")
local bool = tool:WaitForChild("On")

local flashlight = RS.flashlight
local Clone = flashlight:Clone()

local Brightness = 5

Clone.Parent = char

RunService.RenderStepped:Connect(function()
	if Clone then
		Clone.Position = cam.CFrame.Position
		TS:Create(Clone, TI, {CFrame = CFrame.lookAt(Clone.Position,mouse.Hit.Position)}):Play()

		if bool.Value == true then
			TS:Create(Clone.SpotLight, TI, {Brightness = Brightness}):Play()
		elseif bool.Value == false then
			TS:Create(Clone.SpotLight, TI, {Brightness = 0}):Play()
		elseif batteryLevel.Value <= 0 then
			TS:Create(Clone.SpotLight, TI, {Brightness = 0}):Play()
		end

	end
end)

Try copy the script and paste it into a server script and for player just write game:GetService("Players"):GetPlayerFromCharacter(script.Parent.Parent)
(if its directly inside the flashlight)

doesn’t work, the output prints out “Attempt to index nil with “Hit”” line 29

Or make a server script in ServerScriptService and put a RemoteEvent inside the ReplicatedStorage Then copy the whole RenderSteped part paste it into the server script.
Server script:

game:GetService("ReplicatedStorage").RemoteEvent.OnServerEvent:Connect(function(player, tool, cam)

local RS = game:GetService("ReplicatedStorage")
local RunService = game:GetService("RunService")
local TS = game:GetService("TweenService")

local TI = TweenInfo.new(.1, Enum.EasingStyle.Sine)
local char = player.Character or player.CharacterAdded:Wait()
local mouse = player:GetMouse()
local batteryLevel = char:WaitForChild("BatteryLevel")
local bool = tool:WaitForChild("On")

local flashlight = tool
local Clone = flashlight:Clone()

local Brightness = 5

RunService.RenderStepped:Connect(function()
	if Clone then
		Clone.Position = cam.CFrame.Position
		TS:Create(Clone, TI, {CFrame = CFrame.lookAt(Clone.Position,mouse.Hit.Position)}):Play()

		if bool.Value == true then
			TS:Create(Clone.SpotLight, TI, {Brightness = Brightness}):Play()
		elseif bool.Value == false then
			TS:Create(Clone.SpotLight, TI, {Brightness = 0}):Play()
		elseif batteryLevel.Value <= 0 then
			TS:Create(Clone.SpotLight, TI, {Brightness = 0}):Play()
		end

	end
end)
end)

LocalScript(inside the tool):

local tool = script.Parent
local cam = workspace.CurrentCamera

tool.Equipped:Connect(function()
    game:GetService("ReplicatedStorage"):WaitForChild("RmoteEvent"):FireServer(tool, cam)
end)

Why do you want to make this server-side? Visual effects should always be client-sided, so that:

  1. The server has less things to worry about and therefore reduces network usage and increases performance
  2. The effects are smooth and dependent on the player’s own device instead of a potentially bad and laggy internet connection

Because it’s a horror game, if your flashlight runs out of battery then you have to rely on your friend’s flashlight

#7

Ok, but why does it need to be server-side? You can have the client disable the flashlight when it reaches 0 charge, and have the client know what charge the flashlight has through the server changing an attribute.

Is this an attempt to combat exploits?

#8

Yeah, so the player’s can’t get unlimited battery for example. i shouldn’t trust the client

#9

I figured it out, it was really simple.
I had a local script always firing a remote event sending the camera’s position and mouse’s position and applied it with a server script

#10

Exploiters can still do that by creating their own light objects. You aren’t losing anything by making the flashlight be more responsive by handling it on the client ¯\__(ツ)__/¯

#11

I can just detect if a new light object is added and remove it

#12

So it won’t lag on the client side i made a flashlight part for the client and one for the server, so the client part will only show to the client and the server part will only show to the server

#13

Exploiters can always bypass client checks. They could also completely disable the lighting system, making everything look fully-lit:

(look closely, on Kreekcraft’s perspective, the door is completely black, but on the exploiters perspective, it’s lit up and perfectly visible)
