getElementData

[Stevenn]

Hello, i have a question. How can I check if I have my element data below 50 like:

-- lets say my element data is 23 which is below 50, it should do this: 
if getElementData (  localPlayer, "rank" ) ~= 0-50 then  
outputChatBox ( "hey" )  

[Guest Guest4401]

if getElementData ( localPlayer, "rank" ) < 50 then 
    outputChatBox ( "hey" ) 
end

"Attempted to compare string with number"

Your data 'rank' return string type. Convert string to number with function

tonumber 

if tonumber( getElementData ( localPlayer, 'rank' ) ) < 50 then 
    outputChatBox 'hey' 
end 

If this not working try check what return data 'rank'.

you forgot ")" in outputChatBox

No. It's normal. If you call function with 1 argument and this argument is string or table you not need use '( )'.

Example

  
print 'ye' -- ye 
for _, s in pairs { '1', '2' } do 
    print( s )  
    --[[ Output: 
    1 
    2 
    ]] 
end

Okay, thanks but how can I do something like this:

function rank () 
if tonumber( getElementData ( localPlayer, "rank" ) ) < 50 then 
outputChatBox ( "502" ) 
elseif tonumber( getElementData ( localPlayer, "rank" ) ) < 50-115 then -- i know its wrong, but I have no idea..  
end 
addEventHandler ( "onClientResourceStart", root, rank )

Okay, thanks but how can I do something like this:

end 
addEventHandler ( "onClientResourceStart", root, rank ) 
  

Explain this:

elseif tonumber( getElementData ( localPlayer, "rank" ) ) < 50-115 then 

I don't understand.

[Stevenn]

Example: If I have 0-50 points it will do something, but if I have 50-115 it will do something different, and then if I have 115-500 it will do different and so on..

[Kenix]

function rank ( ) 
    local nData = tonumber( getElementData ( localPlayer, 'rank' ) or 0 ) 
    if nData > 0 and nData < 50 then 
        -- TODO 
    elseif nData > 50 and nData < 115 then 
        -- TODO 
    elseif nData > 115 and nData < 500 then 
        -- TODO 
    end 
end 
addEventHandler ( 'onClientResourceStart', resourceRoot, rank ) 

?

[Stevenn]

Omg, I love you thanks kenix!

one last thing then I'm done ( I think )

if I change my element data, I have to restart the resource for it to update my label, how can I add a timer or something?

Why? I don't understand.

[Stevenn]

Okay so, if I kill a player I will get one point which will then be showed on a label.

but, if I kill another player I have to restart the resource in order to update the label

[ben_wright]

use

  
guiSetText 
--with 
setTimer 
--------- example ----------- 
  
myLabel = guiCreateLabel ... 
  
uText = guiSetText ( myLabel, "Example" ) 
  
--timer: 
  
updateTimer = setTimer ( uText, 1000, 1, "example update" ) 
  
  

[Kenix]

use

  
guiSetText 
--with 
setTimer 
--------- example ----------- 
  
myLabel = guiCreateLabel ... 
  
uText = guiSetText ( myLabel, "Example" ) 
  
--timer: 
  
updateTimer = setTimer ( uText, 1000, 1, "example update" ) 
  
  

Your example wrong

updateTimer = setTimer ( uText, 1000, 1, "example update" ) 

You call function uText, but this function not exists.

Correct

local pLabel = guiCreateLabel( 0.5, 0.5, 0.5, 0.5, '', true ) 
guiSetText( pLabel, 'Label' ) 
  
setTimer( guiSetText, 1000, 1, pLabel, 'Updated' )

you don't have to do that, you could use a timer to destroy the label and if the player kills another person before the label could be removed, then you could reset the timer and set the label to the new killer and the player killed, use these:

setTimer() --set a timer so the label could disapper 
resetTimer() -- reset the timer if the player kills another person again 
--then 
guiSetText() -- set the label to the player that killed again 

[Stevenn]

Isn't it just possible to update the function which I use to set the guiText ? In this case:

function rank () 

[Kenix]

setTimer( rank, 1000, 1 ) 

?

[TAPL]

do you need setTimer?

when you kill player you can use event onClientPlayerWasted with guiSetText()

https://wiki.multitheftauto.com/wiki/OnC ... ayerWasted

[Jaysds1]

ok, here's an example:

addEventHandler("onClientPedWasted",root,function() 
   if(isElement(label))then 
      resetTimer(timer) 
      guiSetText(label,killer" killed "..source) 
   else 
      label = createLabel() 
      timer = setTimer(destroyElement,7000,1,label) 
   end 
end) 

[Stevenn]

function kills () 
    local nData = tonumber( getElementData ( localPlayer, 'kills' ) or 0 ) 
    if nData > 0 and nData <50 then 
        guiSetText ( killLabel, "Kills: "..getElementData (localPlayer, "kills") ) 
    elseif nData > 50 and nData < 115 then 
    guiSetText ( killLabel, "Kills: "..getElementData (localPlayer, "kills") ) 
    end 
end 
addEventHandler ( "onClientResourceStart", root, kills ) 
  
setTimer ( kills, 1000, 1 )  

It doesn't work, if I get a new point, nothing happens until i restart the resource.

Shouldn't be on any event, should be updated even if I set my element data using the admin panel

[Jaysds1]

function kills () 
    local nData = tonumber( getElementData ( localPlayer, 'kills' ) or 0 ) 
    if nData > 0 and nData <50 then 
        guiSetText ( killLabel, "Kills: "..getElementData (localPlayer, "kills") ) 
    elseif nData > 50 and nData < 115 then 
    guiSetText ( killLabel, "Kills: "..getElementData (localPlayer, "kills") ) 
    end 
end 
addEventHandler ( "onClientResourceStart", root, kills ) 
  
setTimer ( kills, 1000, 1 )

You never created a label,

plus you set the timer to work 1 timer, set the 1 to 0

[TAPL]

function kills () 
    local nData = tonumber( getElementData ( localPlayer, 'kills' ) or 0 ) 
    if nData > 0 and nData <50 then 
        guiSetText ( killLabel, "Kills: "..getElementData (localPlayer, "kills") ) 
    elseif nData > 50 and nData < 115 then 
    guiSetText ( killLabel, "Kills: "..getElementData (localPlayer, "kills") ) 
    end 
end 
addEventHandler ( "onClientResourceStart", root, kills ) 
  
setTimer ( kills, 1000, 1 )  

It doesn't work, if I get a new point, nothing happens until i restart the resource.

Shouldn't be on any event, should be updated even if I set my element data using the admin panel

I suggest to use event onClientElementDataChange
