ImageLabel Position in Serverside

Hello! So, I have this rn…

Client:

Server:

But now I have a problem… Dots are not drawn where you click (since they are being drawn server side):

Client:

local lPlr = game.Players.LocalPlayer
local mouse = lPlr:GetMouse()
local uis = game:GetService("UserInputService")
local Flash_DrawScript = game:GetService("ReplicatedStorage"):WaitForChild("Flash_DrawScript")

local isMouseButtonDown = false

local function InputBegan(input)
	local inputType = input.UserInputType
	if inputType == Enum.UserInputType.MouseButton1 then
		isMouseButtonDown = true
	end
end

function InputEnded(input)
	local inputType = input.UserInputType
	if inputType == Enum.UserInputType.MouseButton1 then
		isMouseButtonDown = false
	end
end

local function Paint(X, Y)
	if isMouseButtonDown == false then return end
	return Flash_DrawScript:FireServer(X, Y)
end

uis.InputBegan:Connect(InputBegan)
uis.InputEnded:Connect(InputEnded)

for _, frame in ipairs(lPlr.PlayerGui.DrawGui:GetChildren()) do
	if not frame:IsA("Frame") or frame.Name == "Options" then return end
	print(frame)
	frame.MouseMoved:Connect(Paint)
end

Server:

Flash_DrawScript.OnServerEvent:Connect(function(plr, X, Y)
	print("X: "..X.." Y: "..Y)
	for _, frame in ipairs(plr.PlayerGui.DrawGui:GetChildren()) do
		if not frame:IsA("Frame") or frame.Name == "Options" then return end
		
		local gui_X = frame.AbsolutePosition.X
		local gui_Y = frame.AbsolutePosition.Y
		local offset = Vector2.new(math.abs(X - gui_X), math.abs(Y - gui_Y - 36))
		local dot = Instance.new("ImageLabel")
		dot.Parent = frame
		dot.Position = UDim2.new(0, offset.X, 0, offset.Y)
		dot.Name = "Dot"
		dot.ImageColor3 = Color3.fromRGB(0, 0, 0)
		dot.BackgroundTransparency = 1
		dot.Size = UDim2.new(0, 4, 0, 4)
		dot.Image = "http://www.roblox.com/asset/?id=279918838"
		return dot
	end
end)

Btw, I know some things are a little disorganized or poorly optimized, but first I’m focusing on making this work.

I don’t recommend doing this on the server. VFX and local things should strictly be done on the client.

However, your script is likely not working because of this:

After the first iteration of a frame, the loop will just end there. In addition to the fact that you cannot return a value through RemoteEvents (RemoteFunctions serve that purpose)

So, now I have something like this:

Client:

local lPlr = game.Players.LocalPlayer
local mouse = lPlr:GetMouse()
local uis = game:GetService("UserInputService")
local Flash_DrawScript = game:GetService("ReplicatedStorage"):WaitForChild("Flash_DrawScript")

local isMouseButtonDown = false

local function InputBegan(input)
	local inputType = input.UserInputType
	if inputType == Enum.UserInputType.MouseButton1 then
		isMouseButtonDown = true
	end
end

function InputEnded(input)
	local inputType = input.UserInputType
	if inputType == Enum.UserInputType.MouseButton1 then
		isMouseButtonDown = false
	end
end

for _, frame in ipairs(lPlr.PlayerGui.DrawGui:GetChildren()) do
	if not frame:IsA("Frame") or frame.Name == "Options" then return end
	local function Paint(X, Y)
		if isMouseButtonDown == false then return end
		Flash_DrawScript:FireServer(frame, X, Y, isMouseButtonDown)
	end
	uis.InputBegan:Connect(InputBegan)
	uis.InputEnded:Connect(InputEnded)
	frame.MouseMoved:Connect(Paint)
end

Server:

Flash_DrawScript.OnServerEvent:Connect(function(plr, frame, X, Y)
	print(frame)
	local gui_X = frame.AbsolutePosition.X
	local gui_Y = frame.AbsolutePosition.Y
	local offset = Vector2.new(math.abs(X - gui_X), math.abs(Y - gui_Y - 36))
	local dot = Instance.new("ImageLabel")
	dot.Parent = frame
	--dot.Position = UDim2.new(0, offset.X, 0, offset.Y)
	dot.Position = UDim2.new(0, offset.X, 0, offset.Y)
			--[[
			dot.Position = UDim2.new(
				(X - frame.AbsolutePosition.X) / frame.AbsoluteSize.X,
				0,
				(Y - frame.AbsolutePosition.Y) / frame.AbsoluteSize.Y,
				0
			)
			]]
	dot.Name = "Dot"
	dot.ImageColor3 = Color3.fromRGB(0, 0, 0)
	dot.BackgroundTransparency = 1
	dot.Size = UDim2.new(0, 4, 0, 4)
	dot.Image = "http://www.roblox.com/asset/?id=279918838"	
	
	--for _, frame in ipairs(plr.PlayerGui.DrawGui:GetChildren()) do
		--if not frame:IsA("Frame") or frame.Name == "Options" then continue end
		
		
		--frame.MouseMoved:Connect(function(X, Y)	
			
		--end)	
	--end
end)

But it still doesn’t work. (Btw, yes, I need the dot to be created serverside this time)
