Lua Snippets

Common Lua patterns for FiveM resources, including ESX examples. Adjust framework exports and player lookups to the versions your server runs. Check that a player object exists, validate all requested amounts and identifiers, and keep money or inventory mutations inside trusted server-side code.

Server: Get Player


-- QBCore
local Player = QBCore.Functions.GetPlayer(source)
 
-- ESX
local xPlayer = ESX.GetPlayerFromId(source)

Server: Add Money


-- QBCore
Player.Functions.AddMoney('cash', 100)
 
-- ESX
xPlayer.addMoney(100)

Client: Show Notification


-- Using ox_lib
lib.notify({
    title = 'Server',
    description = 'Message here',
    type = 'success'
})

Client: Thread with Wait


CreateThread(function()
    while true do
        Wait(1000)
        -- Do something
    end
end)

Debounced Event

Server-side, keyed per player so one player cannot block everyone else:


local lastTime = {}
 
RegisterNetEvent('myresource:action', function()
    local src = source
    local now = GetGameTimer()
    if lastTime[src] and now - lastTime[src] < 1000 then return end
    lastTime[src] = now
    -- Do action
end)
 
AddEventHandler('playerDropped', function()
    lastTime[source] = nil
end)
