Normal chatchannel fechando automatico

[granoob 2]

estou colocando um sistema antibot, porem ele tem um problema porque não achei um melhor ainda, quando o jogador responde a pergunta o chat fica aberto no qual ele para de notifica o jogador

alguem saber um script o metodo desse chat fechar automaticamente

 

segue o script abaixo

 

function onJoin(player)
    if not player then
        return true
    end

    if not ANTI_BOT_SYSTEM.cache.players[player:getId()] or ANTI_BOT_SYSTEM.cache.players[player:getId()].verified == false then
        player:popupFYI('You can\'t open this channel.')
        return false
    end

    addEvent(function() player:sendChannelMessage("", string.format(ANTI_BOT_SYSTEM.messages.channel_enter.msg, ANTI_BOT_SYSTEM.config.timeToAnswer), ANTI_BOT_SYSTEM.messages.channel_enter.type, ANTI_BOT_SYSTEM.config.channelId) end, 300)
    addEvent(function()
            local random = math.random(#ANTI_BOT_SYSTEM.questions)
            player:sendChannelMessage("", ANTI_BOT_SYSTEM.questions[random].question, TALKTYPE_CHANNEL_R1, ANTI_BOT_SYSTEM.config.channelId)
            ANTI_BOT_SYSTEM.cache.question = random
        end, 2000)  
    addEvent(vericationBot, ANTI_BOT_SYSTEM.config.timeToAnswer * 1000, player:getId())
    return true
end

function onLeave(player)
    if not player then
        return true
    end

    if ANTI_BOT_SYSTEM.cache.players[player:getId()] then
        player:openChannel(ANTI_BOT_SYSTEM.config.channelId)
        addEvent(function() player:sendChannelMessage("", ANTI_BOT_SYSTEM.messages.channel_close.msg, ANTI_BOT_SYSTEM.messages.channel_close.type, ANTI_BOT_SYSTEM.config.channelId) end, 300)
    end
end

function onSpeak(player, type, message)

    player:sendChannelMessage(player:getName(), message, TALKTYPE_CHANNEL_Y, ANTI_BOT_SYSTEM.config.channelId)

    if message ~= ANTI_BOT_SYSTEM.questions[ANTI_BOT_SYSTEM.cache.question].answer then
       addEvent(function() player:sendChannelMessage("", ANTI_BOT_SYSTEM.messages.wrong_answer.msg, ANTI_BOT_SYSTEM.messages.wrong_answer.type, ANTI_BOT_SYSTEM.config.channelId) end, 300)
    else
        addEvent(function() player:sendChannelMessage("", ANTI_BOT_SYSTEM.messages.correct_answer.msg, ANTI_BOT_SYSTEM.messages.correct_answer.type, ANTI_BOT_SYSTEM.config.channelId) end, 300)
        ANTI_BOT_SYSTEM.cache.players[player:getId()] = nil
    end
    return false
end
