[HELP] Anti spam command script

hello!

I don't want it to kick people, just that it doesn't allow you to do a command more than 1 time in a certain time, thanks!

Just replace kickPlayer function to your outputChatBox.

The message appear but I still can make the command

Interesting solution @Patrick , I am hardly using metatables so I have always trouble to get around the default table logic.

btw I am wondering is the rawset function not required to set the value on line 26?

This code from onPlayerCommand's wiki page, I just edited and put the command name check inside it.

Hmm, looks like unnecessary.

Here is my solution, I hope its good for you.

local LIMITED_COMMANDS = {
    -- ["COMMAND_NAME"] = TIME_LIMIT_IN_SEC
    ["something"] = 5,  -- Can use this command only once in every 5 sec
    ["spam"]      = 10, -- Can use this command only once in every 10 sec
}

local EXEC = {}

addEventHandler("onPlayerCommand", root, function(cmd)
    local limit_sec = LIMITED_COMMANDS[cmd]
    if not limit_sec then return end

    local tick = getTickCount()

    if not EXEC[source]      then EXEC[source] = {}     end
    if not EXEC[source][cmd] then EXEC[source][cmd] = 0 end

    if EXEC[source][cmd] + (limit_sec * 1000) > tick then
        cancelEvent()
        return outputChatBox("#FF0000[ANTISPAM]#FFFFFF You can use this command once, in every "..limit_sec.." sec.", source, 255, 255, 255, true)
    end
    EXEC[source][cmd] = tick
end)

addEventHandler("onPlayerQuit", root, function()
    EXEC[source] = nil
end)

First of all... stop spamming...
And provide more informations about what are you doing, because it has to work.

y453bh · April 8, 2020

Can you give me the lines for antispam only?, so I can add them to all my scripts?

Because this way isnt't working, please @Patrick

Oh.. you can't cancel client sided commands.

Then, here is one way, how to limit commands on client side:

local EXEC = {}

function canUse(cmd, limit_sec)
    if not EXEC[cmd] then EXEC[cmd] = 0 end
	
    local lastuse = EXEC[cmd]
    local tick    = getTickCount()
      
    if lastuse + ((limit_sec or 2) * 1000) > tick then
        return false
    end

    EXEC[cmd] = tick
    return true
end


-- EXAMPLE

function yourFunction(cmd)
    -- Need to add this part to your functions
    if not canUse(cmd, 2) then
        return outputChatBox("#FF0000[ANTISPAM]#FFFFFF You can use this command once, in every 2 sec!")
    end

    -- your code ...
end
addCommandHandler("asd", yourFunction)

    end

    -- your code ...
end

That's what I needed, thanks a lot @Patrick

Here is another one... you need just add the cmd to "cmdAntiSPAM" table like the example:

local cmdAntiSPAM = {
     -- {cmd,usageLimit,time,dataName},
    {"say",5,3000,"CMD_SAY"},
    {"help",1,3000,"CMD_HELP"},
}
function preventCommandSpam(command)
    for i,v in ipairs(cmdAntiSPAM) do
        if v[1] == command then
        local data = getElementData(source,v[4])
            if data then
            local spam = data+1
                if spam >= v[2] then
                    cancelEvent()
                    outputChatBox ("You need to wait before using this command again!", source, 255, 0, 0, false)
                else
                    setElementData(source,v[4],spam)
                end
            else
                setElementData(source,v[4],0)
                setTimer(removeSPAMData,v[3],1,source,v[4])
            end
        end
    end
end
addEventHandler("onPlayerCommand", getRootElement(), preventCommandSpam)

function removeSPAMData(player,data)
    if isElement(player) then
        removeElementData(player,data)
    end
end

I hope this can help you.
