Variable

[hemen]

How to get the variable from server-side script in client-side, or from server-side script in client-side?

Are there some functions, besides getElementData?

Another way would be to transfer them using events, but setting the element data is fine too.

events are better anyway - cause it's easier to make an action after sending values ie. from server to client.

i know about onClientElementDataChange - but it's more complicated i think

[hemen]

I created function, which receive and return value of variable.

--Client-side script.
function getvar1(varname,number)
triggerServerEvent("getvar1",getRootElement(),gMe,varname,number)
return getElementData(gMe,"variable")
end

--Server-side script.
function getvar1 (player,varname,number)
local var = " "
if varname == "name" then			
		var = GangInfo.Name[number]
elseif varname == "leader" then 	
		var = GangInfo.Leader[number] 
end
setElementData(player,"variable",var)
end
 
addEvent( "getvar1", true )
addEventHandler( "getvar1", getRootElement(), getvar1 )

But it's need to wait some value of milliseconds up to starting next function. Example:

--Client-side
outputChatBox(""..getvar1("name",gangid).."")

Script doesn't writes value of variable, because there are interval from receiving value of variable to writing of message.

How it can be fixed?

i suggest not to use setElementData.

triggerServerEvent, and after doing some actions triggerClientEvent back.

waiting some ms in unreliable - sometimes server/client can get a lag..

But what can i do, if triggerServerEvent and triggerClientEvent doesn't return a value of variable?

[dzek (varez)]

i dont understand what you mean

[hemen]

I'm sorry, i speak english very bad.

I'll answer the question in the different way. How recieve* a value of server-side script's variable by (with ?) function triggerServerEvent?

[dzek (varez)]

-- sending value from client to server, and back to client
 
--[[
CLIENT SIDE SCRIPT
]]--
addEvent("sendToClient", true)
addEventHandler("sendToClient", getRootElement(), function(var1)
outputChatBox("got variable from server: ".. var1)
end)
 
myVar = "hello world!"
triggerServerEvent("sendToServer", getLocalPlayer(), myVar)
 
 
--[[
SERVER SIDE SCRIPT
]]--
addEvent("sendToServer", true)
addEventHandler("sendToServer", getRootElement(), function(var1)
 varToSend = var1.." server says hello too!"
triggerClientEvent(source, "sendToClient", source, varToSend)
end)

try this script,

look on wiki pages for triggerServerEvent and triggerClientEvent (click on them in script above)

I'm sure you will understand it

[hemen]

I understood only that this function concentrates on itself, there is a recursion.

I didn't understand, when did this function started from.

I need only in function, which receive values of variables from server-side to client-side.

@hemen

You can't simply have a function which returns a server-side variable in client-side script, or the other way around... You have to trigger events back and forth.

[dzek (varez)]

there is NO recursion in my example..
