dxDrawText server side, or some way to do it..

DarkLink · June 21, 2011

Hi guys, I want to put a timer using dxDrawText. I could do it, when I was using for client..

But there would be a timer different for each player that connects server, and thats not what I need

I need a timer to be set by server when first player log in, then wait 30 secs . ( this timer would appear on that client 30..29..28...)

And if another player would log in while the timer was decreasing, his timer (another player), would also continue decreasing, not starting from 30 again.

U guys can understand?

If dxDrawText worked via server side, would work .. but no

My friend told me to use triggerClientEvent and setTimer, communicating server with client .

So I managed to do this, but I dont understand much the addEvent and his trigger, if u guys could give me some hints

server:

  
local sec = "30" 
function onPlayerJoinBind () 
  bindKey ( source, "l", "down", VehicleLights ) 
  setTimer(triggerClientEvent, 1000, 30, "mostrarSegundos", root, sec) 
   
end 
addEventHandler ( "onPlayerJoin", getRootElement(), onPlayerJoinBind  )

client:

  
function createText() 
     
        if (tonumber(segundos)==0) then 
            return 
        end 
         
        X,Y = guiGetScreenSize () 
        X = X * (2.5/3) 
        Y = Y * (1/4) 
        dxDrawText ( segundos, X, Y, X, Y, tocolor(255, 255, 255, 255), 5) 
         
end 
  
  
  
addEvent( "mostrarSegundos", true ) 
addEventHandler( "mostrarSegundos", getRootElement(), mostrarSegundos ) 
function mostrarSegundos (sec) 
     
    segundos = sec 
    addEventHandler("onClientRender",rootElement, createText)  
end

btw I know I have to decrease the sec to print it on dxDrawText, but I dont know where

Thanks guys, and sorry for asking

function onJoin () 
  if not( timerValue == true )then 
  timerValue = true  
  getTimerValue () 
end 
addEventHandler ( "onPlayerJoin", getRootElement(), onJoin ) 
  
function getTimerValue () 
  if ( timerValue == true ) then 
  triggerClientEvent ( getRootElement(), "showDX", getRootElement() ) 
  setTimer ( setValue, 30000,1 ) 
  elseif (timerValue == false) then 
  triggerClientEvent ( getRootElement(), "hideDX", getRootElement() ) 
  end 
end 
  
function setValue () 
  timerValue = false  
  getTimerValue () 
end 
  
function onStart () 
  setTimer ( getTimerValuea(), 50,0) 
end 
addEventHandler("onResourceStart", getResourceRootElement(getThisResource()), onStart )

function showDX () 
  addEventHandler ( "onClientRender", getRootElement(), drawDX ) 
end 
addEvent ( "showDX", true ) 
addEventHandler ( "showDX", getRootElement(), showDX ) 
  
function drawDX () 
             
        X,Y = guiGetScreenSize () 
        X = X * (2.5/3) 
        Y = Y * (1/4) 
        dxDrawText ( segundos, X, Y, X, Y, tocolor(255, 255, 255, 255), 5) 
         
end 
  
function hideDX () 
  removeEventHandler ( "onClientRender", getRootElement(), drawDX ) 
end 
addEvent ( "hideDX ", true ) 
addEventHandler ( "hideDX ", getRootElement(), hideDX )

Client side timers will not work for all players. So, do all things in server side, and create text in client side. Good luck, hope it work =)

Thanks for ur reply, but where is the segundos decreasing ? I mean the segundos-- ? so will go drawing 30, then 29 .. to 0 ?

ty again

DarkLink · June 21, 2011

Hey CowTurbo I have been working on these but isnt working..

Your solution, doesnt work too CowTurbo.

I made it showing numbers from 30 to ( - infinite ), but the numbers are going to fast, not in each second .

So I made the corrections to ur code:

CLIENT

  
function showDX (segundos) 
  sec = segundos 
  addEventHandler ( "onClientRender", getRootElement(), drawDX ) 
end 
addEvent ( "showDX", true ) 
addEventHandler ( "showDX", getRootElement(), showDX ) 
  
function drawDX () 
            
        X,Y = guiGetScreenSize () 
        X = X * (2.5/3) 
        Y = Y * (1/4) 
        dxDrawText ( sec, X, Y, X, Y, tocolor(255, 255, 255, 255), 5) 
         
        
end 
  
function hideDX () 
  removeEventHandler ( "onClientRender", getRootElement(), drawDX ) 
end 
addEvent ( "hideDX ", true ) 
addEventHandler ( "hideDX ", getRootElement(), hideDX )

SERVER

  
segundos = "30" 
function onJoin () 
  if not( timerValue == true )then 
  timerValue = true 
  getTimerValue () 
  end 
end 
addEventHandler ( "onPlayerJoin", getRootElement(), onJoin ) 
  
function getTimerValue () 
  if ( timerValue == true ) then 
  setTimer(escreve, 1000, 30) 
   
  setTimer ( setValue, 30000,1 ) 
  elseif (timerValue == false) then 
  triggerClientEvent ( getRootElement(), "hideDX", getRootElement() ) 
  end 
end 
  
  
  
function escreve () 
  
triggerClientEvent ( getRootElement(), "showDX", getRootElement(), segundos ) 
newnumber = (tonumber(segundos)-1) 
segundos = tostring(newnumber) 
--triggerClientEvent ( getRootElement(), "hideDX", getRootElement(), segundos ) 
end 
  
function setValue () 
  timerValue = false 
  getTimerValue () 
end 
  
function onStart () 
  timerValue = false 
  setTimer ( getTimerValue, 50,0) 
end 
addEventHandler("onResourceStart", getResourceRootElement(getThisResource()), onStart )

This is the hardest things of MTA Scripting that I cant understand much. Handlers, Events, and Sync beetween client and server functions.

So I would appreciate some help from pros

Thanks alot guys !

I really want to know how to this , I want to learn it.

Thanks

Castillo · June 21, 2011

Ok, look, I think the best way you could do this would be using element data, which is synced between client and server.

--server side

segundos = 30 
timerEnabled = false 
  
function onJoin () 
if timerEnabled then 
setElementData(source,"secondsRemaining",tostring(segundos)) 
triggerClientEvent ( source, "showDX", source) 
  end 
end 
addEventHandler ( "onPlayerJoin", getRootElement(), onJoin ) 
  
function escreve () 
timerEnabled = true 
for i,v in pairs(getElementsByType("player")) do 
setElementData(v,"secondsRemaining",tostring(segundos)) 
triggerClientEvent ( v, "showDX", v ) 
end 
setTimer(countDown,1000,30) 
end 
addCommandHandler("inciarcontador",escreve) 
  
function countDown() 
segundos = segundos -1 
for i,v in pairs(getElementsByType("player")) do 
setElementData(v,"secondsRemaining",tostring(segundos)) 
end 
if segundos == 0 then 
triggerClientEvent ( "hideDX", getRootElement() ) 
timerEnabled = false 
  end 
end 
  
function onStart () 
  timerEnabled = false 
end 
addEventHandler("onResourceStart", getResourceRootElement(getThisResource()), onStart )

--client side

function drawDX ()        
    X,Y = guiGetScreenSize () 
    X = X * (2.5/3) 
    Y = Y * (1/4) 
    dxDrawText ( getElementData(getLocalPlayer(),"secondsRemaining"), X, Y, X, Y, tocolor(255, 255, 255, 255), 5) 
end 
  
function showDX () 
  addEventHandler ( "onClientRender", getRootElement(), drawDX ) 
end 
addEvent ( "showDX", true ) 
addEventHandler ( "showDX", getRootElement(), showDX ) 
  
function hideDX () 
  removeEventHandler ( "onClientRender", getRootElement(), drawDX ) 
end 
addEvent ( "hideDX ", true ) 
addEventHandler ( "hideDX ", getRootElement(), hideDX )

When you type /iniciarcontador it will start the count down, when it reaches 0 it will stop and hide the DX element.

P.S: CowTurbo, your code makes no sense for me.

Thanks SolidSnake, it does the job I guess, didnt tryed yet.

But in this case I had to write that command every time I want to run this gamemode.

Is there a way to start it write after 2 players online ?

Thanks.

Castillo · June 21, 2011

Yes, it is possible, use this:

segundos = 30 
timerEnabled = false 
  
function onJoin () 
if timerEnabled then 
setElementData(source,"secondsRemaining",tostring(segundos)) 
triggerClientEvent ( source, "showDX", source) 
  end 
if getPlayerCount ( ) >= 2 then 
escreve() 
  end 
end 
addEventHandler ( "onPlayerJoin", getRootElement(), onJoin ) 
  
function escreve () 
timerEnabled = true 
for i,v in pairs(getElementsByType("player")) do 
setElementData(v,"secondsRemaining",tostring(segundos)) 
triggerClientEvent ( v, "showDX", v ) 
end 
setTimer(countDown,1000,30) 
end 
  
function countDown() 
segundos = segundos -1 
for i,v in pairs(getElementsByType("player")) do 
setElementData(v,"secondsRemaining",tostring(segundos)) 
end 
if segundos == 0 then 
triggerClientEvent ( "hideDX", getRootElement() ) 
timerEnabled = false 
  end 
end 
  
function onStart () 
  timerEnabled = false 
end 
addEventHandler("onResourceStart", getResourceRootElement(getThisResource()), onStart )

  end

for i,v in pairs(getElementsByType("player")) do

triggerClientEvent ( v, "showDX", v ) 
end 
setTimer(countDown,1000,30) 
end 
  
function countDown() 
segundos = segundos -1 
for i,v in pairs(getElementsByType("player")) do 
setElementData(v,"secondsRemaining",tostring(segundos)) 
end 
if segundos == 0 then

timerEnabled = false 
  end 
end 
  
function onStart () 
  timerEnabled = false 
end 
addEventHandler("onResourceStart", getResourceRootElement(getThisResource()), onStart )

Thanks alot solid

Its working with the two options, in the second option just had to change from

  
.. 
if getPlayerCount ( ) >= 2 then 
escreve() 
  end 
end 
..

to

  
.. 
if getPlayerCount ( ) >= 2 then 
   setTimer(escreve, 50,1) 
end 
end 
..

but there is only a little problem, the removeEventHandler is not working

segundos will reach 0 but it doesnt trigger the event hideDX, I guess..

and dont know why

the zero keeps there on the screen..

Thanks bro

Thanks for ur reply, but still not working.

And I dont get it, why u do this

  
if segundos >= 0 then 
triggerClientEvent ( "hideDX", getRootElement() ) 
timerEnabled = false 
  end

So would hide it before reach zero. the condition on IF is >= 0 .

So why?

Thanks, and sorry about ur time .

Castillo · June 22, 2011

My bad, I wanted to do: <= 0 , copy code again.

DarkLink · June 22, 2011

My bad, I wanted to do: <= 0 , copy code again.

I tryed that too when u told me, cos it wasnt making sense to me.

But also didnt worked..

Any clue?

The zero keeps there in the monitor.. :c

Wojak · June 22, 2011

if you have any doubt that the part of the code is not running, add some output lines, you can also output variables to check it they have corect values when they ate neede't.

If you can not make removeEventHandler to work, set the segundos as empty string after 0

segundos = ""

I though that too, but It will cause some lag I thing. because the event will always triggered.. onClientRender, causing some lags ?

Thanks!!

EDIT: It should work removeEventHandler, and I dont know why is not working

Wojak · June 22, 2011

no one should notice the FPS drop with one text, but try to debug your code anyway

Thanks .

Bro I did what u recommend, and I guess this DxDrawText is bugged

When I put this : outputChatBox("okay working")

at here

  
    function hideDX () 
      outputChatBox("okay working", getRootElement()) 
      removeEventHandler ( "onClientRender", getRootElement(), drawDX) 
    end 
    addEvent ( "hideDX ", true ) 
    addEventHandler ( "hideDX ", getRootElement(), hideDX )

I dont even can see the timer starting.. from 30 to 0..

I restart gamemode, I restart server.. I restart gta..

Nothing..

Can someone tell me the problems of this event? onClientRender?

Thanks!

Castillo · June 22, 2011

The event is wrong, check this: "hideDX " it has an SPACE.

function drawDX ()       
    X,Y = guiGetScreenSize () 
    X = X * (2.5/3) 
    Y = Y * (1/4) 
    dxDrawText ( getElementData(getLocalPlayer(),"secondsRemaining"), X, Y, X, Y, tocolor(255, 255, 255, 255), 5) 
end 
  
function showDX () 
  addEventHandler ( "onClientRender", getRootElement(), drawDX ) 
end 
addEvent ( "showDX", true ) 
addEventHandler ( "showDX", getRootElement(), showDX ) 
  
function hideDX () 
  removeEventHandler ( "onClientRender", getRootElement(), drawDX ) 
end 
addEvent ( "hideDX", true ) 
addEventHandler ( "hideDX", getRootElement(), hideDX )

Now it's removing the text.

LOOOL!!

I failed so much, a little thing like a space changes everything

Thanks alot bro!

Working ;D

No problem .

dxDrawText server side, or some way to do it..
