Making Shop System

Help and Feedback Scripting Support
#1

Hello devleopers, i want to make a shop system with owned items (not a buy item again just equip) i have a local script with the scripts, but i don’t know how to make owned items.
I want to make:

  1. Equip Items

newTemplate script:

local folder = game.ReplicatedStorage:WaitForChild("Tools")

local frame = script.Parent:WaitForChild("Items")

local template = frame:WaitForChild("Template")

for _, tool in pairs(folder:GetChildren()) do
	local newTemplate = template:Clone()
	newTemplate.Name = tool.Name
	newTemplate.ObjectName.Text = tool.Name
	newTemplate.Visible = true 
	newTemplate.Parent = frame

	local object = tool:Clone()
	object.Parent = newTemplate.ViewportFrame

	local camera = Instance.new("Camera")
	camera.CFrame = CFrame.new(object.Handle.Position + (object.Handle.CFrame.lookVector*5)+Vector3.new(2,2,2), object.Handle.Position)
	camera.Parent = newTemplate.ViewportFrame
	newTemplate.ViewportFrame.CurrentCamera = camera	
	
	newTemplate.MouseButton1Click:Connect(function()
		local result = game:GetService("ReplicatedStorage").Events.Buy:InvokeServer(tool.Name)
		if result == true then
			newTemplate.BackgroundColor3 = Color3.fromRGB(55,255,85)
		else
			newTemplate.BackgroundColor3 = Color3.fromRGB(255,60,0)
		end
		wait(1)
		newTemplate.BackgroundColor3 = Color3.fromRGB(255,255,255)
	end)
end

buy event script:

replic.Buy.OnServerInvoke = function(player, toolName)
	local tool = game.ReplicatedStorage.Tools:FindFirstChild(toolName)
	if tool and not player.StarterGear:FindFirstChild(toolName) then
		if tool:FindFirstChild("Cost")  then

		if tool.Cost.Value <= player.leaderstats.Deti.Value then
			-- buy

			player.leaderstats.Deti.Value -= tool.Cost.Value
			
			local newTool = tool:Clone()
			newTool.Parent = player.Backpack

			local newTool = tool:Clone()
			newTool.Parent = player.StarterGear
	
			return true
		else
			return false
		end
	else 
		return false end
	end
end
