Skrip tombol upgrade

Di ReplicatedStorage, buat folder bernama Instances.

Di dalam folder Instances, buat ScreenGui bernama JumpPurchaseGui dengan ResetOnSpawn dinonaktifkan.

Di dalam JumpPurchaseGui, buat TextButton bernama JumpButton dengan properti berikut:
- Teks: "Upgrade Jump (5 Koin)"
- UkuranTeks: 25
- TitikJangkar: 1, 1
- Posisi: {1, 0}, {1, 0}

Juga di dalam folder Instances, buat RemoteFunction bernama IncreaseJumpPowerFunction.

Akhirnya, di layanan StarterPlayer, aktifkan properti CharacterUseJumpPower.

Di ServerStorage, ganti kode ModulScript PlayerData yang ada dengan yang berikut:

```lua
local PlayerData = {}

PlayerData.COIN_KEY_NAME = "Coins"
PlayerData.JUMP_KEY_NAME = "Jump"

local playerData = {
	--[[
		[userId: string] = {
			["Coins"] = coinAmount: number,
			["Jump"] = jumpPower: number
		}
	--]]
}

local function defaultPlayerData()
	return {
		[PlayerData.COIN_KEY_NAME] = 0,
		[PlayerData.JUMP_KEY_NAME] = 0,
	}
end

local function getData(player)
	local data = playerData[tostring(player.UserId)] or defaultPlayerData()
	playerData[tostring(player.UserId)] = data
	return data
end

function PlayerData.getValue(player, key)
	return getData(player)[key]
end

function PlayerData.updateValue(player, key, updateFunction)
	local data = getData(player)
	local oldValue = data[key]
	local newValue = updateFunction(oldValue)

	data[key] = newValue
	return newValue
end

return PlayerData
```

Di ServerScriptService, buat Skrip bernama JumpService dengan kode berikut:

```lua
-- Layanan
local ReplicatedStorage = game:GetService("ReplicatedStorage")
local ServerStorage = game:GetService("ServerStorage")
local Players = game:GetService("Players")

-- Modul
local Leaderboard = require(ServerStorage.Leaderboard)
local PlayerData = require(ServerStorage.PlayerData)

-- Acara
local IncreaseJumpPowerFunction = ReplicatedStorage.Instances.IncreaseJumpPowerFunction

local JUMP_KEY_NAME = PlayerData.JUMP_KEY_NAME
local COIN_KEY_NAME = PlayerData.COIN_KEY_NAME
local JUMP_POWER_INCREMENT = 30
local JUMP_COIN_COST = 5

local function updateJumpPower(player, updateFunction)
	-- Perbarui tabel kekuatan melompat
	local newJumpPower = PlayerData.updateValue(player, JUMP_KEY_NAME, updateFunction)

	-- Perbarui kekuatan melompat pemain
	local character = player.Character or player.CharacterAdded:Wait()
	local humanoid = character:FindFirstChildWhichIsA("Humanoid")
	if humanoid then
		humanoid.JumpPower = newJumpPower

		-- Perbarui papan peringkat melompat
		Leaderboard.setStat(player, JUMP_KEY_NAME, newJumpPower)
	end
end

local function onPurchaseJumpIncrease(player)
	local coinAmount = PlayerData.getValue(player, COIN_KEY_NAME)
	if coinAmount < JUMP_COIN_COST then
		return false
	end

	-- Tingkatkan kekuatan melompat pemain
	updateJumpPower(player, function(oldJumpPower)
		oldJumpPower = oldJumpPower or 0
		return oldJumpPower + JUMP_POWER_INCREMENT
	end)
	-- Perbarui tabel koin
	local newCoinAmount = PlayerData.updateValue(player, COIN_KEY_NAME, function(oldCoinAmount)
		return oldCoinAmount - JUMP_COIN_COST
	end)
	-- Perbarui papan peringkat koin
	Leaderboard.setStat(player, COIN_KEY_NAME, newCoinAmount)
	return true
end

local function onCharacterAdded(player)
	-- Reset kekuatan melompat pemain saat karakter ditambahkan
	updateJumpPower(player, function(_)
		return 0
	end)
end

-- Inisialisasi pemain yang ditambahkan sebelum terhubung ke acara PlayerAdded
for _, player in Players:GetPlayers() do
	onCharacterAdded(player)
end

-- Inisialisasi normal pemain dari acara PlayerAdded
local function onPlayerAdded(player)
	player.CharacterAdded:Connect(function()
		onCharacterAdded(player)
	end)
end

local function onPlayerRemoved(player)
	updateJumpPower(player, function(_)
		return nil
	end)
end

IncreaseJumpPowerFunction.OnServerInvoke = onPurchaseJumpIncrease
Players.PlayerAdded:Connect(onPlayerAdded)
Players.PlayerRemoving:Connect(onPlayerRemoved)
```

Di ReplicatedStorage, buat Skrip bernama JumpButtonClickHandler dengan RunContext diatur ke Client dan kode berikut:

```lua
local ReplicatedStorage = game:GetService("ReplicatedStorage")
local Players = game:GetService("Players")

local player = Players.LocalPlayer
local playerGui = player.PlayerGui

local IncreaseJumpPowerFunction = ReplicatedStorage.Instances.IncreaseJumpPowerFunction
local jumpPurchaseGui = ReplicatedStorage.Instances.JumpPurchaseGui
local jumpButton = jumpPurchaseGui.JumpButton

local function onButtonClicked()
	local success, purchased = pcall(IncreaseJumpPowerFunction.InvokeServer, IncreaseJumpPowerFunction)
	if not success then
		-- purchased akan menjadi pesan kesalahan jika success adalah false
		error(purchased)
	elseif success and not purchased then
		warn("Koin tidak cukup!")
	end
end

jumpButton.Activated:Connect(onButtonClicked)

-- Tambahkan JumpPurchaseGui ke Gui pemain
jumpPurchaseGui.Parent = playerGui
```
