Clearing Data (Element Data)

[DarkLink]

Hi there, I am trying to get a easy and best way to clear all the data, I mean the data I saved using setElementData (on players, teams, objects..)

This is for starting a new round on my gamemode, I was using "stopResource" and "startResource" again.. but I think its not a good way to do it.

Thanks alot in advance

removeElementData 

?

[Guest Guest4401]

for k,v in pairs(getAllElementData(player)) do 
    removeElementData(player,k) 
end 
--"player" should be an element 

[Kenix]

  
addEventHandler( 'onResourceStop', resourceRoot, 
    function( ) 
        for _, pPlayer in ipairs( getElementsByType 'player' ) do 
            for sData, _ in pairs( getAllElementData( pPlayer ) ) do 
                removeElementData( pPlayer, sData ) 
            end 
        end 
    end 
)

Thanks guys

karthik can I use instead of player something to index everything ? maybe getAllElementData(getRootElement()) ?

Thanks.

Try

addEventHandler( 'onResourceStop', resourceRoot, 
    function( ) 
        for sData, _ in pairs( getAllElementData( root ) ) do 
            removeElementData( root, sData ) 
         end 
    end 
)

for _, sData in ipairs( getAllElementData( pPlayer ) ) do 
    removeElementData( pPlayer, sData ) 
end 

Should be pairs because it has a key & a value

And the key is supposed to be removed, not value

oO lol? getAllElementData return table with ( key( number ) value (string) )

no, key is string

[Kenix]

Ah damn. My bad. Didn't see in first time about key is string on the wiki

Hm I see, and to clear everything.. ? instead of use "player" ? is there something that refers to every type of element?

code at first file and first line of the resource:

  
local _eKeys = {} 
local _setElementData = setElementData 
function setElementData(p,k,...) 
    _setElementData(p,k,...) 
    _eKeys[k] = true 
end 
function clearElementData() 
    for _,v in pairs(getElementsByType"player") do 
        for k in pairs(_eKeys) do 
            removeElementData(v,k) 
        end 
    end 
end 
  

must be server side.

    end 
end

This will only remove data that was set by the resource this code is in. Also, author keeps asking about root element.

@DarkLink, you can use getElementChildren to get all the elements and then remove their data with removeElementData

Okay thanks alot mate

[qaisjp]

which mate me or 50p or both.

Yes 50p, he is doing this for his borderpatrol gamemode which is one resource, if you remove all element data, servers with other resources that use element data alongside BP GM will have problems

[DarkLink]

both ofc, yes I only want to clear the data of my resource, not others. if I use as root element my resource, its fine right?

In that case, you can get children of your resource and then remove their data, will work if you're changing data of your resource's children (vehicles, objects, markers, etc. created with your resource). If you're changing player's data then you can set player's parent to your resource when they join your server. There are many options. It's up to you which one you pick.

[DarkLink]

Okay thanks alot again, btw how can I set player's parent resource ? is there some function native ?

[qaisjp]

You don't need to set the players parent resource. What kind of crazy idea do you have for that ?
