A system health check for Roblox

[XXOTIC-1]

(Create a RemoteEvent in ReplicatedStorage named SystemCheckRemote)

-- ServerScriptService/SystemCheckServer.lua

local Players = game:GetService("Players")
local ReplicatedStorage = game:GetService("ReplicatedStorage")
local remote = ReplicatedStorage:WaitForChild("SystemCheckRemote")

local focusOffCounter = {}
local maxFocusLoss = 5 -- Number of times allowed to Alt+Tab before kick

remote.OnServerEvent:Connect(function(player, data)
if not data then return end

-- Handle focus loss tracking
if data.FocusLost then
	local count = (focusOffCounter[player.UserId] or 0) + 1
	focusOffCounter[player.UserId] = count

	warn("[Focus Lost] " .. player.Name .. " | Count: " .. count)

	if count >= maxFocusLoss then
		player:Kick("You have been kicked for switching windows too often.")
	end
	return
end

-- Handle system check
if data.SystemCheck then
	local info = data.SystemCheck
	print("[SystemCheck] " .. player.Name)
	print("  Device: " .. tostring(info.DeviceType))
	print("  Platform: " .. tostring(info.Platform))
	print("  Input: " .. tostring(info.InputType))
	print("  Time since join: " .. math.floor(info.TimePlayed) .. "s")
	print("  Network Ping: " .. tostring(info.Ping))
	print("  Memory Usage: " .. tostring(info.Memory) .. " MB")
end

end)

-- Reset focus counter on player leave
Players.PlayerRemoving:Connect(function(player)
focusOffCounter[player.UserId] = nil
end) (put this in server script)

-- StarterPlayerScripts/SystemCheckClient.lua

local Players = game:GetService("Players")
local RunService = game:GetService("RunService")
local ReplicatedStorage = game:GetService("ReplicatedStorage")
local UserInputService = game:GetService("UserInputService")
local Stats = game:GetService("Stats")

local remote = ReplicatedStorage:WaitForChild("SystemCheckRemote")
local startTime = tick()

-- 📦 Send system info
local function sendSystemData()
local timePlayed = tick() - startTime
local memory = math.floor(Stats:GetTotalMemoryUsageMb())
local ping = math.floor(Stats.Network.ServerStatsItem["Data Ping"]:GetValue())
local device = UserInputService:GetPlatform()
local inputType = UserInputService.TouchEnabled and "Touch" or (UserInputService.KeyboardEnabled and "Keyboard" or "Gamepad")

remote:FireServer({
	SystemCheck = {
		DeviceType = device,
		InputType = inputType,
		Platform = UserInputService:GetPlatform().Name or "Unknown",
		TimePlayed = timePlayed,
		Ping = ping,
		Memory = memory,
	}
})

end

-- 🔁 Periodic system check every 30 seconds
task.wait(5)
sendSystemData()
while true do
task.wait(30)
sendSystemData()
end

-- 🔍 Focus lost detection (Alt+Tab or tab out)
UserInputService.WindowFocusReleased:Connect(function()
remote:FireServer({FocusLost = true})
end) (put this in local script and place it in starter scripts service)
