    GetElementData server/client

    in Scripting

    I would like to know how I could get ElementData from server to client and vice versa

      

    
-- server side
marker = createMarker(0, 0, 1.5, "cylinder", 2, 255, 0, 0)

setElementData(marker, "Item", 5)

addEvent("GetItem", true)

addEventHandler("GetItem", root, function()
  	ClientMarker = marker
    
    ItemOfClientMarker = getElementData(marker, "Item")
  end)

addEventHandler("onMarkerHit", marker, function(hp)
    triggerClientEvent("Element", resourceRoot)
    
  	setElementData(hp, "ItemTwo", ElementVariable+getElementData(marker, "Item"))
  end)

-- client side
function dxDrawTextOnElement(TheElement,text,height,distance,R,G,B,alpha,size,font,...)
	local x, y, z = getElementPosition(TheElement)
	local x2, y2, z2 = getCameraMatrix()
	local distance = distance or 20
	local height = height or 1

	if (isLineOfSightClear(x, y, z+2, x2, y2, z2, ...)) then
		local sx, sy = getScreenFromWorldPosition(x, y, z+height)
		if(sx) and (sy) then
			local distanceBetweenPoints = getDistanceBetweenPoints3D(x, y, z, x2, y2, z2)
			if(distanceBetweenPoints < distance) then
				dxDrawText(text, sx+2, sy+2, sx, sy, tocolor(R or 255, G or 255, B or 255, alpha or 255), (size or 1)-(distanceBetweenPoints / distance), font or "arial", "center", "center")
			end
		end
	end
end

setElementData(getLocalPlayer(), "ItemTwo", 0)

addEvent("Element", true)

addEventHandler("Element", root, function()
  	ElementVariable = getElementData(getLocalPlayer() , "ItemTwo")
  end)

addEventHandler("onClientRender", root, function()
    triggerServerEvent("GetItem", root)
    
	dxDrawTextOnElement(ClientMarker, tostring(ItemOfClientMarker), 2, 50, 255, 255, 0, 3, "arial")
  end)

    Does it have a chance to work? because that's something I imagine...

    You should fix it, before your server will die out of endless triggering. 

    addEventHandler("onClientRender", root, function()
triggerServerEvent("GetItem", root)--give an order to make this event "getItem" run in server per frame
end)

    Trigger client/server even should be well maintained. Right now, you call this function every frame, what if more players will join?

    Local player is actually the client!

    So server side script hasn't local player because the script is server side :)

    you should use this in client side 

    
triggerServerEvent("EventName",localPlayer) -- localPlayer = source of the event in server side

    and you can receive your event from server side like this : 

    
addEvent("EventName",true)
addEventHandler("EventName",root,
  function()
    local localPlayer = source; -- source is that player you put in the triggerServerEvent
    -- now you have the localPlayer in the server
  end
)

    also, there are another methods you can use, but this is a simple example.

     

    Note :

    When you need to use the localPlayer in server side, you will be automatically must be using the triggerServerEvent function.

    So in the logic you have to trigger an event

     

    When you want to use localPlayer?

    Using source variable isn't safe. 

    function EventName()
	if client then
		outputChatBox("Hi player!", client)
	end
end
addEvent("EventName", true)
addEventHandler("EventName", root, EventName)
    Quote
    • All parameters including 'source' can be faked and should not be trusted.
    • Global variable 'client' can be trusted.

    [help] showing name and distance when aiming

    Hello i want to do script that when player aim, you will see player nick and distance between you and player that you aiming at ( sorry for english ) i did something like this 

    
if playerTarget then
  local x,y,z = getElementPosition(playerTarget)
  local x,y,distance = getScreenFromWorldPosition (x,y,z+0.5)
  distance = 30
  if getElementData(playerTarget,"bandit") then
    text = string.gsub(getPlayerName(playerTarget), '#%x%x%x%x%x%x', '' ) else
    text = string.gsub(getPlayerName(playerTarget), '#%x%x%x%x%x%x', '' ) end
  local w = dxGetTextWidth(text,distance*0.033,"default-bold") 
  if w and x and y and text and distance then
    dxDrawText ( text.."("..(getDistanceBetweenPoints3D( x,y,z, getElementPosition ( localPlayer )))..")",x-(w/5),y,x-(w/5),y,tocolor(100, 255, 100, 200),distance*0.033,"bankgothic") end end end);

    that line is the showing name and distance 

    
dxDrawText text.."("..(getDistanceBetweenPoints3D( x,y,z, getElementPosition ( localPlayer )))..")",x-(w/5),y,x-(w/5),y,tocolor(100, 255, 100, 200),distance*0.033,"bankgothic")

    but i dont know why i have so damn large output

    Perhaps it's your issue: 

    distance*0.033

    It's a text scale.

return tabla
end

    I need clear the table to so that every time the function is executed, no added elements are added

     

    (google translate english xd)

    Just do: 

    tabla = {}

    Before loop.

            end, 2000, 1)
        end 
    end
    addCommandHandler("dig", playerDigTreasure)

    You should use locals whenever you can. 

    local col1 = createColSphere(...)
local col2 = createColSphere(...)
local col3 = createColSphere(...)

do
	col1 = "still local, but it's a string now"
	col2 = "still local, but it's a string now"
	col3 = "still local, but it's a string now"
end

    Tip:

    Attaching resource start event to root will cause that function will be triggered when ANY resource starts, use resourceRoot instead. 

    addEventHandler("onResourceStart", getRootElement(), createTreasure)

    Yes, but load IFP just once. This should work correct if player latejoined, now just do the same, with all players when you loaded IFP (so if you started or restarted resource it will affect all players)

    "This function only affects a specific player or ped, the internal animation is not replaced for everyone, for instance, different players and peds are able to have completely different crouching, walking, and fighting etc., animations running simultaneously at the same time. Also, it's not synchronized, you'll need to execute this function on every client in Lua to synchronize it.", after loading IFP loop all players, and replace animation for them, aswell you will need onClientPlayerJoin to replace animation for him (if he joined late).

    Best practice for storing character data in JSON

    I decided the best course of action would be saving all this character data locally instead of MySQL, here's where my problem comes in.

    What if user will delete cache? Or will manipulate it on other way?

    Do not be afraid to use SQLite/MySQL. If you have lot of data, you can store it in one column as a JSON string aswell.

    Tables aren't synced by default. If you create tables via shared script, they do not have same data (unless you will sync it). Take a look at this topic, might be helpful.

    Tables and shared Lua files

    in Scripting

    Posted

    12 minutes ago, Tekken said:

    So I'm interested into replacing element data functions to more efficient store data into tables but with this comes a problem, syncing the data between client and server so I taught of creating a shared Lua file and building the system there so in this way the functions will work both client/server.

    But will this work?

    Or should I use a make around with the event system?

    Shared won't work.

    Example: 

    -- Client

local clientTable = {}

--

function onClientDataSync(serverData)
	clientTable = serverData
end
addEvent("onClientDataSync", true)
addEventHandler("onClientDataSync", resourceRoot, onClientDataSync)

--

function onClientReceiveVehicleData(...)
	local receivedData = {...}
	local vehicleUserdata = receivedData[1]
	local vehicleData = receivedData[2]

	clientTable[vehicleUserdata] = vehicleData

	outputConsole(inspect(clientTable))
end
addEvent("onClientReceiveVehicleData", true)
addEventHandler("onClientReceiveVehicleData", resourceRoot, onClientReceiveVehicleData)
    -- Server

local serverTable = {}
local newVehicle = createVehicle(411, 0, 0, 3)

--

serverTable[newVehicle] = "Some data you want to pass"

    About sync: 

    --[[Sync for everyone]]

triggerClientEvent(root, "onClientReceiveVehicleData", resourceRoot, newVehicle, serverTable[newVehicle])

--[[When player latejoined - pass data f.e when he logins]]

triggerClientEvent(source, "onClientDataSync", resourceRoot, serverTable)

    why this creates me two separate gridlist instead of introducing them to one?

    You don't check if this gridlist exists.

    About this part of code, you are destroying your server network. 

    for k,v in ipairs(getElementsByType("ped") do
    if getElementData(v, "created") then
      pedsToTrigger = {}
      table.insert(pedsToTrigger, v)

    Trigger will be called 1 * count of peds, it's very bad. Because it could be done with just 1 trigger. 

    -- Client

local pedsGridlist = false

function customEvent(serverTable)
	if not pedsGridlist then
		pedsGridlist = guiCreateGridList(200, 100, 50, 50, false)

local somePed = createPed(11, 0, 0, 3)

-- 1st way, ped will be accessible via number, mostly you will need to loop whole table if there's more elements

someTable[#someTable + 1] = somePed
