-- Instructions for setting up GUI in Roblox Studio 
1. In Roblox Studio, click on the "StarterGui" in the Explorer window.
2. Right-click on "StarterGui" and select "Insert Object" and then choose "ScreenGui".
3. Right-click on the "ScreenGui" you just created and select "Insert Object" and then choose "TextButton" or "ImageButton" for your loot button.
4. Customize the button's appearance and size by modifying its properties in the Properties window.
5. Create a LocalScript inside the button and add the following code to handle button clicks:

local lootButton = script.Parent
local player = game.Players.LocalPlayer

local function onClick()
    local loot = game.ReplicatedStorage:WaitForChild("LootSystem"):InvokeServer(player)
    print("You received " .. loot)
end

lootButton.MouseButton1Click:Connect(onClick)

6. In the ServerScriptService, create a RemoteFunction called "LootSystem" and insert the loot system script inside it.
7. Replace the "game.Players.PlayerAdded" event with the following code to handle the RemoteFunction call:

local LootSystem = game.ServerScriptService:WaitForChild("LootSystem")

local function onInvoke(player)
    return giveLoot(player)
end

LootSystem.OnServerInvoke = onInvoke

Now, when the player clicks the button, it will call the server script to give them a random loot item and display it in their inventory.
