Passing meta settings XML to client

[Jay_]

Hello,

I'm trying to pass my server side settings defined in my meta.xml to the client. However, when passing the table of XML data to the client, the data does not persist.

Here's my server side code:

 

addEvent("onClientRequestResourceSettings", true)
addEventHandler("onClientRequestResourceSettings", resourceRoot,
	function()		

		local xml = xmlLoadFile("meta.xml")             	
		local settingsNode = xmlFindChild(xml, "settings", 0)
		
		if(settingsNode) then
			local settings = xmlNodeGetChildren(settingsNode)   
			triggerClientEvent(client, "onServerProvideResourceSettings", resourceRoot, settings)
		end 
		
        xmlUnloadFile(xml)    
	end 
)

That above event is called client side when the resource starts.

 

Here's the client side code:

 

addEvent("onServerProvideResourceSettings", true)
addEventHandler("onServerProvideResourceSettings", resourceRoot,
	function(theSettings)
		iprint("Settings provided: "..inspect(theSettings)) --Output: "Settings provided: { }"
	end
)

 

However my settings table is not being passed to the client. When printing the output, it appears to be an empty table. I'm aware there is a limitation of passing xml data to the client, however as this is in fact a table data type, I wouldn't of thought there would be an issue?

Can anyone point me in the right direction, or perhaps provide some better solutions for passing settings data from the meta.xml to the client?

Cheers.

The table is fine, but the nodes aren't. Those nodes are nothing more than a reference to the real nodes in the xml, which are only available on the side where the xml is loaded.

Loop through the table and get the real data with https://wiki.multitheftauto.com/wiki/XmlNodeGetAttributes

And send that.

I personally would use setElementData for this, simply save the resource settings as element data to 'resource' (predefined variable) and then you can use the same element on the client to access these data. No need to use events in this case.

You may have to use resourceRoot, I'm not sure which one is correct in this case.

Thanks. This makes perfect sense, I'll go with that.

Ahmed Ly, your code doesn't really make sense to me. I'm not sure why you're explicitly calling xmlFindChild during a strange iteration, when my above method of using xmlNodeGetChildren will retrieve all of the children in a table?

Given that there is potential scope for there to be a large number of settings defined in the XML, I don't agree with this. setElementData is really only designed to sync small amounts of data.

I only need to provide this information once during initialisation of the resource to a single client. setElementData really wouldn't be an efficient way of providing this information over a single event call. It also raises concerns over security as I only want this information to be accessible from within the resource.
