[REL] Protection from Trigger DDos

[Korea]

This simple code will protect you from attacking a server by TriggerServerEvent. Also you can use onPlayerTriggerEventThreshold but I think if player turns off internet and do actions then after turning it on all packets will be send in the same interval.

Change some settings to your own!

-- client side

local ServerCalls
ServerCalls = {
    interval = 1000,
    maxCallsPerInterval = 20,
    time = 0,
    calls = 0,

    refresh = function(self)
        if self.time < getTickCount() then
            self.time = getTickCount() + self.interval
            self.calls = 0
        end
    end,

    add = function(self)
        self:refresh();
        self.calls = self.calls + 1
    end,
}
ServerCalls.__index = ServerCalls

addDebugHook("preFunction", function()

    ServerCalls:add();

    if ServerCalls.calls >= ServerCalls.maxCallsPerInterval and not ServerCalls.makeLastCall then
        triggerServerEvent("banPlayer", resourceRoot)
        ServerCalls.makeLastCall = true
    end

    return ServerCalls.makeLastCall and "skip" or true
end, {"triggerServerEvent"})

-- basic implenemtation of banPlayer (server side)

addEvent("banPlayer", true)
addEventHandler("banPlayer", resourceRoot, function()
    banPlayer(client, true, false, true, "Korea", "Anty ddos")
end)
