Lua Talk event problem.

[Hameq]

Hello.
Today i found bug in talk event function i mean that random player is able to spam it because "cancelNPCTalk(events)" doesn't work in my eyes, this function should stop more than 1 running event or something like that.

Look on this movie:
clip0005 - YouTube

Here is script i hope someone know what to do:

function doCreatureSayWithDelay(cid,text,type,delay,e)
   if delay<=0 then
      doCreatureSay(cid,text,type)
   else
      local func=function(pars)

                    doCreatureSay(pars.cid,pars.text,pars.type)
                    pars.e.done = TRUE

                 end

      e.done = FALSE
      e.event = addEvent(func,delay,{cid=cid, text=text, type=type, e=e})

   end
end
 
--returns how many msgs he have said already
function cancelNPCTalk(events)
  local ret = 1
  for aux = 1, table.getn(events) do
     if events[aux].done == FALSE then
        stopEvent(events[aux].event)
     else
        ret = ret + 1
     end
  end
  events = 0
  return(ret)
end
 
function doNPCTalkALot(msgs,interval)
  local e={}
  local ret={}
  if interval==nil then interval=3000 end --3 seconds is default time between messages
  for aux=1,table.getn(msgs) do
      e[aux]={}
      doCreatureSayWithDelay(getNpcCid(),msgs[aux],TALKTYPE_SAY,(aux-1)*interval,e[aux])
      table.insert(ret,e[aux])
  end
  return(ret)
end
