local staterSpeed = 16

local dfPerPoint = 10

game.Players.PlayerAdded:Connect(function(player)
	local attr = Instance.new("Folder")
	attr.Name = "Attributes"
	attr.Parent = player
	
	local defense = Instance.new("IntValue")
	defense.Name = "Defense"
	defense.Parent = player
	
	local strenght = Instance.new("IntValue")
	strenght.Name = "Strenght"
	strenght.Parent = player
	
	local speed = Instance.new("IntValue")
	speed.Name = "Speed"
	speed.Parent = player
end)

local repStorage = game:GetService("ReplicatedStorage")

local dfRemote = repStorage.Remotes.AddHealth
local spdRemote = repStorage.Remotes.AddSpeed
local strRemote = repStorage.Remotes.AddStrenght

local function PointsAvailable(player)
	local PointsUsed = player.Attributes.Health.Value + player.Attributes.Strenght.Value + player.Attributes.Health.Value
	local PointsAvailable = player.LevelsInfo.Level.Value - PointsUsed
	
	return PointsAvailable > 0
end

dfRemote.OnServerEvent:Connect(function(player)
	
	if not PointsAvailable(player) then return end
	
	player.Attributes.Health.Value += 1
	
	local dfPerPoint = 10
	
	player.Character.Humanoid.MaxHealth = 100 + player.Attributes.Health.Value * dfPerPoint
	player.Character.Humanoid.Health = 100 + player.Attributes.Health.Value * dfPerPoint
	
end)

spdRemote.OnServerEvent:Connect(function(player)
	
	if not PointsAvailable(player) then return end
	
	player.Attributes.Speed.Value += 1
	
	local spdPerPoint = 2
	local starterSpeed = 16
	
	player.Character.Humanoid.WalkSpeed = starterSpeed + player.Attributes.Speed.Value * spdPerPoint
end)


strRemote.OnServerEvent:Connect(function(player)
	
	if not PointsAvailable(player) then return end
	
	player.Attributes.Strenght.Value += 1
end)
