Script un botón de mejora

En ReplicatedStorage, crea una carpeta llamada Instances.

Dentro de la carpeta Instances, crea un ScreenGui llamado JumpPurchaseGui con ResetOnSpawn desactivado.

Dentro de JumpPurchaseGui, crea un TextButton llamado JumpButton con las siguientes propiedades:
- Text: "Mejorar Salto (5 Monedas)"
- TextSize: 25
- AnchorPoint: 1, 1
- Position: {1, 0}, {1, 0}

También dentro de la carpeta Instances, crea una RemoteFunction llamada IncreaseJumpPowerFunction.

Finalmente, en el servicio StarterPlayer, habilita la propiedad CharacterUseJumpPower.

En ServerStorage, reemplaza el código existente del módulo PlayerData con el siguiente:

```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
```

En ServerScriptService, crea un Script llamado JumpService con el siguiente código:

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

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

-- Eventos
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)
	-- Actualiza la tabla de poder de salto
	local newJumpPower = PlayerData.updateValue(player, JUMP_KEY_NAME, updateFunction)

	-- Actualiza el poder de salto del jugador
	local character = player.Character or player.CharacterAdded:Wait()
	local humanoid = character:FindFirstChildWhichIsA("Humanoid")
	if humanoid then
		humanoid.JumpPower = newJumpPower

		-- Actualiza el leaderboard de salto
		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

	-- Aumenta el poder de salto del jugador
	updateJumpPower(player, function(oldJumpPower)
		oldJumpPower = oldJumpPower or 0
		return oldJumpPower + JUMP_POWER_INCREMENT
	end)
	-- Actualiza la tabla de monedas
	local newCoinAmount = PlayerData.updateValue(player, COIN_KEY_NAME, function(oldCoinAmount)
		return oldCoinAmount - JUMP_COIN_COST
	end)
	-- Actualiza el leaderboard de monedas
	Leaderboard.setStat(player, COIN_KEY_NAME, newCoinAmount)
	return true
end

local function onCharacterAdded(player)
	-- Restablece el poder de salto del jugador cuando se añade el personaje
	updateJumpPower(player, function(_)
		return 0
	end)
end

-- Inicializa cualquier jugador añadido antes de conectarse al evento PlayerAdded
for _, player in Players:GetPlayers() do
	onCharacterAdded(player)
end

-- Inicialización normal de jugadores desde el evento 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)
```

En ReplicatedStorage, crea un Script llamado JumpButtonClickHandler con RunContext establecido en Client y el siguiente código:

```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 será el mensaje de error si success es falso
		error(purchased)
	elseif success and not purchased then
		warn("¡No hay suficientes monedas!")
	end
end

jumpButton.Activated:Connect(onButtonClicked)

-- Agrega el JumpPurchaseGui a la GUI del jugador
jumpPurchaseGui.Parent = playerGui
```
