[Master_MTA]

hello all i have gonna to create my own dxlib so i am trying to do something if it wasn't possible you should take  look of my code first   it's work fine without wrong

but i wanna do something better 

function gsplit(text, pattern, plain)
  local splitStart, length = 1, #text
  return function ()
    if splitStart then
      local sepStart, sepEnd = string.find(text, pattern, splitStart, plain)
      local ret
      if not sepStart then
        ret = string.sub(text, splitStart)
        splitStart = nil
      elseif sepEnd < sepStart then
        -- Empty separator!
        ret = string.sub(text, splitStart, sepStart)
        if sepStart < length then
          splitStart = sepStart + 1
        else
          splitStart = nil
        end
      else
        ret = sepStart > splitStart and string.sub(text, splitStart, sepStart - 1) or ''
        splitStart = sepEnd + 1
      end
      return ret
    end
  end
end

 function split(text, pattern, plain)
  local ret = {}
  for match in gsplit(text, pattern, plain) do
    table.insert(ret, match)
  end
  return ret
end

addEventHandler('onClientCharacter',root,function(key)
	for k,v in ipairs(getElementsByType('dxEditBox',resourceRoot))do
		if getElementData(v,'line')==true and dxGetVisible(v)==true then
			local data=getElementData(v,'info')
			local text=data.text..key
				setElementData(v,'info',{
				text=text,
					id=data.id,
					x=data.x,
					y=data.y,
					x1=data.x1,
					y1=data.y1,
					color=data.color,
					postgui=data.postgui,
					textcolor=data.textcolor,
					dxWindow=data.dxWindow
				})
			break
		end
	end
end)
addEventHandler('onClientKey',root,function(button,press)
if press then
if button=='backspace' then
for k,v in ipairs(getElementsByType('dxEditBox',resourceRoot))do
if dxGetVisible(v)==true and getElementData(v,'line') and getElementData(v,'line')==true then
local data=getElementData(v,'info')
text=''
for k,v in ipairs(split(data.text,''))do
if k==#split(data.text,'') then break end
text=text..v
end
				setElementData(v,'info',{
				text=text,
					id=data.id,
					x=data.x,
					y=data.y,
					x1=data.x1,
					y1=data.y1,
					color=data.color,
					postgui=data.postgui,
					textcolor=data.textcolor,
					dxWindow=data.dxWindow
				})
break
end
end
end
end
end)

setTimer

or

onClientRender

getKeyState

Thats just about using the getKeyState function into a renderer using tickCounts to differentiate the situations ( delete one 500ms or delete more less than 100ms ).
