Grid system help

Hey, I have a simple code for a placement system but if I wanted to add a grid how would I do that?

Here is my current code:


Written Form:

local player = game.Players.LocalPlayer
local RunService = game:GetService(“RunService”)
local UIS = game:GetService(“UserInputService”)

script.Parent.Enabled = true

for i,v in pairs(script.Parent.MainBuildFrame:GetChildren()) do
if v:IsA(“ImageButton”) then
v.MouseButton1Click:Connect(function()
local PreviewItem = game.ReplicatedStorage.Items:FindFirstChild(v.Name)
local RoatingObject = false
local RotationAmmount = 0

		if PreviewItem then
			local NewItem = PreviewItem:Clone()
			NewItem.Parent = workspace
			NewItem.Transparency = 0.5
			NewItem.CanCollide = false
			
			local Mouse = player:GetMouse()
			
			UIS.InputBegan:Connect(function(Input, GameProccessed)
				if Input.KeyCode == Enum.KeyCode.R then
					if not GameProccessed then
						
						RoatingObject = true
						
						while RoatingObject == true do
							task.wait()
							RotationAmmount += 0.01
						end
						
					end
				end
			end)
			
			UIS.InputEnded:Connect(function(Input)
				if Input.KeyCode == Enum.KeyCode.R then
					RoatingObject = false
					
				end
			end)
			
			RunService.RenderStepped:Connect(function()

				Mouse.TargetFilter = NewItem

				NewItem.Position = Vector3.new(Mouse.Hit.Position.X, Mouse.Hit.Position.Y + NewItem.Size.Y / 2, Mouse.Hit.Position.Z)
				
				if RoatingObject == true then
					local ObjectAngles = CFrame.Angles(0,math.rad(RotationAmmount),0)

					NewItem.CFrame = NewItem.CFrame * ObjectAngles
				end
			end)
		end
	end)
end

end

I think the way people add a grid, is just placing a grid image down on the ground

Then if you use Texture, you can scale the grid to whatever

How would I script that in my game?..

try cloning and sizing it to the size of the placement area

What’s the issue? Any errors in console?
