local player = game.Players.LocalPlayer
local leaderstats = player:WaitForChild("leaderstats")
local xp = leaderstats:WaitForChild("XPT")
local level = leaderstats:WaitForChild("RankT")

local xpData = {
	Team1 = 0,
	Team2 = 0,
	Team3 = 0,
	Team4 = 0
}

local xpPerMinute = 500

local rankCooldown = 0
local xpCooldown = 5

local function checkAndUpdateRank()
	while wait(rankCooldown) do
		local teamColor = player.TeamColor

		if teamColor == BrickColor.new("Really red") then
			if xpData.Team1 >= 500 and level.Value == "Loading" then
				level.Value = "O5-1"
			elseif xpData.Team1 >= 1500 and level.Value == "O5-1" then
				level.Value = "O5-2"
			elseif xpData.Team1 >= 4000 and level.Value == "O5-2" then
				level.Value = "O5-3"
			elseif xpData.Team1 >= 12000 and level.Value == "O5-3" then
				level.Value = "O5-4"
			end
		elseif teamColor == BrickColor.new("Forest green") then
			if xpData.Team2 >= 500 and level.Value == "Loading" then
				level.Value = "SID-1"
			end
		elseif teamColor == BrickColor.new("CGA brown") then
			if xpData.Team3 >= 500 and level.Value == "Loading" then
				level.Value = "CD-1"
			end
		elseif teamColor == BrickColor.new("Really black") then
			if xpData.Team4 >= 500 and level.Value == "Loading" then
				level.Value = "L-1"
			end

	end
end

local function checkAndUpdateXP()
	while wait(xpCooldown) do
		local teamColor = player.TeamColor

		if teamColor == BrickColor.new("Really red") then
			xpData.Team1 = math.min(xpData.Team1 + xpPerMinute, 12000)
		elseif teamColor == BrickColor.new("Forest green") then
			xpData.Team2 = math.min(xpData.Team2 + xpPerMinute, 12000)
		elseif teamColor == BrickColor.new("CGA brown") then
			xpData.Team3 = math.min(xpData.Team3 + xpPerMinute, 12000)
		elseif teamColor == BrickColor.new("Really black") then
			xpData.Team4 = math.min(xpData.Team4 + xpPerMinute, 12000)
		end

		xp.Value = xpData.Team1 + xpData.Team2 + xpData.Team3 + xpData.Team4
	end
end
