Triggering Events and sending variables

FiveM Resource Development Discussion
1

So this is my first time trying to do this on fivem. Im trying to update my text client side with variable from the server updated from my database, All my variables very side come back accurate but when I trigger the client command nothing happens.

client

Citizen.CreateThread(function()



    while true do

        Citizen.Wait(1)

            money("Bank:", pMoney)
			xp("XP: ", pXP)
			

    end

end)

AddEventHandler("playerSpawned", function()
	TriggerServerEvent("playerAccount", source)
end)

RegisterCommand('updateStats', function()
    local source = GetPlayerServerId(PlayerId())
    TriggerServerEvent('updatePlayerStats', source)

end)

Server

RegisterNetEvent("updatePlayerStats")
AddEventHandler("updatePlayerStats", function(playerMoney, playerXP, playerLevel)
	
	MySQL.Async.fetchAll('SELECT * FROM accounts WHERE user = @username', {['@username'] = GetPlayerName(source)}, function(result)
	local playerMoney = result[1].money
	local playerXP    = result[1].xp
	local playerLevel = result[1].level
	
	pMoney = playerMoney
	pXP    = playerXP
	pLevel = playerLevel
	
	
	end)
	
	
end)

Ive searched through the docs and forums but not of my solutions seem to work.

This is probably the issue you should use PlayerPedId()

@ChieF-TroN Not necessarily, as GetPlayerServerId() takes a player not a ped.

This is not required, as source is always defined inside the server side Event Handler, you just need to call it.

Also you could just move this to the server script, save passing any events at all, since RegisterCommand() is a server side native as well.

I created the command just to check if the variables her sent over accurately before I make them act on their own. So far the variables arenā€™t updating. Anything I set the int to initialize as is what is outputted in chat.

This is the entire client side of the text im drawing and trying to update

local pMoney = 1
local pXP = 1
local pLevel = 1

function money(content) 
    SetTextFont(1)
    SetTextProportional(0)
    SetTextScale(0.5, 0.5)
    SetTextEntry("STRING")
    AddTextComponentString(content)
    DrawText(0.9,0.2)

end

function xp(content) 
    SetTextFont(1)
    SetTextProportional(0)
    SetTextScale(0.5,0.5)
    SetTextEntry("STRING")
    AddTextComponentString(content)
    DrawText(0.9,0.3)

end

Citizen.CreateThread(function()



    while true do

        Citizen.Wait(1)

            money("Bank:", pMoney)
			xp("XP: ", pXP)
			

    end

end)

AddEventHandler("playerSpawned", function()
	TriggerServerEvent("playerAccount", source)
end)



RegisterCommand('updateStats', function()
    local source = GetPlayerServerId(PlayerPedId())
    TriggerServerEvent('updatePlayerStats', source)
	
	TriggerEvent('chat:addMessage', {
  color = { 255, 0, 0},
  multiline = true,
  args = {"Me", "Money: "..pMoney}
})
end)

Im still fighting with this

Iā€™m not that experienced with MySQL but what comes to my mind is:

Server side

--mysql start
   pMoney = playerMoney
   pXP    = playerXP
   pLevel = playerLevel
--mysql end

should be a table for players like:

local pMoney = {}
local pXP = {}
local pLevel = {}

...
--mysql start
   pMoney[source] = playerMoney
   pXP[source]    = playerXP
   pLevel[source] = playerLevel
--mysql end

ā€œsourceā€ for each player on server since all players are synced with the same ā€˜server.lua / scriptā€™ server side, so need a table (or array if you prefer C# or C++) for players

Send me a PM or whatever and I can send a basic example of what I mean once Iā€™m around PC again

Will do! Iā€™m away from my code atm but I will hit you up. Itā€™s highly appreciated

9

But it looks like Iā€™m setting the trigger up correctly tho, right?

10

All the examples I see are always triggering chat messages and that doesnā€™t help explain much

11

your client side:

TriggerServerEvent("playerAccount", source)

I believe doesnā€™t require you to send source like that, itā€™s automatically sent to server side as a ā€˜hiddenā€™ variable, then server side you can just get it with the variable ā€œsourceā€

Like this:

Client:

function SetCash(data)
	TriggerServerEvent('SetCharCash', data)
end

Server:

RegisterNetEvent('SetCharCash')
AddEventHandler('SetCharCash', function(data)
	srvCash[source] = data
end)

At least it works for me that way, that source is always sent automatically from client to server via events/functions. BUT Iā€™m not completely sure if you should or shouldnā€™t send source separately.

Also server side I need to do

local src = source

in MySQL functions in events or I just get source as nil inside the MySQL function/query. No idea why I canā€™t just use source, so if you run into problems with that stuff, try that. Iā€™m probably missing something simple, maybe someone can explain it

12

I updated my script but it says im trying to concatenate a nil value so im assuming ive done it wrong and still getting a nil return.

client

function updateStats()
    local source = GetPlayerServerId(PlayerPedId())
    TriggerServerEvent('updatePlayerStats', playerMoney, playerXP, playerLevel)
	
	pMoney = playerMoney
	
	TriggerEvent('chat:addMessage', {
  color = { 255, 0, 0},
  multiline = true,
  args = {"Me", "Money: "..pMoney}
	})
end

server

RegisterNetEvent("updatePlayerStats")
AddEventHandler("updatePlayerStats", function(playerLevel, playerXP, playerLevel)
	
	MySQL.Async.fetchAll('SELECT * FROM accounts WHERE user = @username', {['@username'] = GetPlayerName(source)}, function(result)
	playerMoney = result[1].money
	playerXP    = result[1].xp
	playerLevel = result[1].level
	
	end)
	
	
end)
13

client:

local playerMoney = 54345 -- or whatever you have on these variables
local playerXP = 4 -- or whatever you have on these variables
local playerLevel = 13 -- or whatever you have on these variables

...

function updateStats()
    TriggerServerEvent('updatePlayerStats', playerMoney, playerXP, playerLevel)
end

server:

playerMoney = {} -- table/array serverside for each player, like a list of all players' money
playerXP = {} -- table/array serverside for each player, like a list of all players' XP
playerLevel = {} -- table/array serverside for each player, like a list of all players' level

...

RegisterNetEvent("updatePlayerStats")
AddEventHandler("updatePlayerStats", function(playerMoney, playerXP, playerLevel)
	local src = source

	MySQL.Async.fetchAll("SELECT money, xp, level FROM accounts WHERE user = " .. GetPlayerName(src), {}, function(result)
		TriggerClientEvent('chat:addMessage', src, { args = { "t: ".. result[1].money .." " .. result[1].xp .." ".. result[1].level} })
		print(result[1].money) -- print to server side console to see what values you get with anything server side

		playerMoney[src] = result[1].money
		playerXP[src]    = result[1].xp
		playerLevel[src] = result[1].level

		TriggerClientEvent('chat:addMessage', src, { args = { "tserverside: ".. playerMoney[src] .." " .. playerXP[src] .." ".. playerLevel[src]} })
	end)
end)

Try that, I think I have some mistake in it, not sure but should work

Trying to understand how triggering the events work in general, Im drawing text on the client side. I wanna update the text with variables from the server side.

Do I initialize the money variable on the server side and then

triggerclientevent(ā€œeventnameā€, money variable)

and then set the text variable to the money variable?

15

Found out I should have been triggering a client event instead of a server event, so I was doing it backwards.
