XML question

[mjau]

Hi i got a small problem with a XML file

if i want to get a specified line/house out of the code below how?

im asking this cuz i wanna make so when a player hits the pikup for the house it shows price owner housename etc

<houseData> 
    <house markerPosX="-1302.248046875" markerPosY="-111.3232421875" markerPosZ="14.1484375" houseName="nab" owner="nil"></house> 
    <house markerPosX="-1303.59375" markerPosY="-111.072265625" markerPosZ="14.1484375" houseName="blabla" owner="nil"></house> 
    <house markerPosX="-1308.1611328125" markerPosY="-109.3642578125" markerPosZ="14.1484375" houseName="heytrololo" owner="nil"></house> 
    <house markerPosX="-1307.861328125" markerPosY="-112.10546875" markerPosZ="14.1484375" houseName="blahhh" owner="nil"></house> 
    <house markerPosX="-1305.9541015625" markerPosY="-114.6572265625" markerPosZ="14.1484375" houseName="cake:D" owner="nil"></house> 
</houseData> 

So if i hit thepickup created for the house named cake:D it shows its prices etc

Having an unique ID for every house is good idea, but using XML for a house system is not that good. Loading very big XML files with more than 1000+ houses and that much data may cause server lag problems (tested). I suggest you using other ways to store the houses.

P.S : You can use setElementData to give an unique ID for every house when you load the houses.

Or you can use SQLite.

Use your xml to map

You can use getElementsByType

And you can use your house data/markers and etc.

I always use this in gm , because you can create something in map editor and easy change it.

In gm you just get data in map.

Eh expalin further please and anyway i need to get the exact house that belongs to that pickup(if u want i can pm u my code ...)

[Kenix]

it created marker( get house elements in map file ).

local marker 
  
local function onHit ( element,dim ) 
    if getElementType( element ) == 'player' and not isPedInVehicle( element ) then 
        -- your code 
    end 
end 
  
local function onLeave ( element,dim ) 
    if getElementType( element ) == 'player' and not isPedInVehicle( element ) then 
        -- your code 
    end 
end 
  
addEventHandler( 'onResourceStart',resourceRoot, 
    function( ) 
        local markers = getElementsByType 'house' 
        if #markers > 0 then 
            for _,v in pairs( markers ) do 
                marker = createMarker(  
                    getElementData( 'markerPosX' ), 
                    getElementData( 'markerPosY' ), 
                    getElementData( 'markerPosZ' ) 
                ) 
                setElementData( marker,'houseName',getElementData( v,'houseName' ) ) 
                setElementData( marker,'owner',getElementData( v,'owner' ) ) 
                addEventHandler( 'onMarkerHit',marker,onHit )    
                addEventHandler( 'onMarkerLeave',marker,onLeave )    
            end 
        end 
    end 
)    

Also you can create edf for easy change you houses in map editor.

( Just change marker pos and etc ).

For owner , houseName and etc better use SQL/MySQL.
