Anti Crash Script Roblox Better Now

Exploiters can fire your remotes hundreds of times per second, causing lag crashes. A bucketed rate limiter is essential.

-- Script inside a ModuleScript required by your remote handler
local remoteThrottle = {}
function remoteThrottle.isAllowed(player, remoteName, cooldownSeconds)
local playerKey = player.UserId
local now = tick()
if not remoteThrottle[playerKey] then
    remoteThrottle[playerKey] = {}
end
local lastFire = remoteThrottle[playerKey][remoteName] or 0
if now - lastFire < cooldownSeconds then
    warn("[AntiCrash] Throttled ", player.Name, " on ", remoteName)
    return false
end
remoteThrottle[playerKey][remoteName] = now
return true

end
-- Usage in a RemoteEvent:
local myRemote = game.ReplicatedStorage:FindFirstChild("MyEvent")
myRemote.OnServerEvent:Connect(function(player, data)
if not remoteThrottle.isAllowed(player, "MyEvent", 0.2) then
return -- Ignore spam
end
-- Process data safely
end)

Better tuning: Use 0.05 for movement, 0.2 for attacks, and 2.0 for chat or trading. anti crash script roblox better

Detects runaway loops and yields them.

local LoopMonitor = {}
local loopIterations = {}
function LoopMonitor.wrapWhile(conditionFunc, bodyFunc, maxIterations)
local iter = 0
return function()
iter = iter + 1
if iter > maxIterations then
task.wait() -- force yield to prevent freeze
iter = 0
end
return conditionFunc()
end
end

Use with:

local condition = LoopMonitor.wrapWhile(function() return running end, nil, 10000)
while condition() do
    -- your loop body
end

Exploiters can spam FireAllClients with massive strings. A better anti-crash validates data size.

Server-side (Remote Event):

local REMOTE = game.ReplicatedStorage:WaitForChild("MyRemote")
REMOTE.OnServerEvent:Connect(function(player, data)
-- ANTI-CRASH: Check data size
if type(data) == "string" and #data > 5000 then
warn(player.Name .. " attempted to send massive string. Kicked.")
player:Kick("Data limit exceeded")
return
end
-- Process normal data
end)

Instead of blocking all remotes, block only those sent faster than 0.04 seconds.

local cooldown = {}
local function canFire(remote)
    local last = cooldown[remote] or 0
    if tick() - last < 0.04 then return false end
    cooldown[remote] = tick()
    return true
end

Prevents event connection spam (e.g., thousands of Changed events).

local ConnectionLimiter = {}
local connectionCounts = setmetatable({}, __mode = "k") -- weak keys
local oldConnect = RBXScriptSignal.connect
function RBXScriptSignal:connect(fn)
local callingScript = debug.info(2, "s") -- script source
connectionCounts[callingScript] = (connectionCounts[callingScript] or 0) + 1
if connectionCounts[callingScript] > 500 then
    error("[AntiCrash] Too many connections from script: " .. tostring(callingScript))
end
return oldConnect(self, fn)

end

local AntiCrash = {}
function AntiCrash.init()
-- Load all subsystems
require(script.InstanceBlocker)
require(script.ConnectionLimiter)
require(script.LoopMonitor)
require(script.CrashRecovery)
require(script.MemoryMonitor)
print("[AntiCrash] Smart Resilience System active")

end
return AntiCrash
