QBCore Events Reference - QBCore Guide for FiveM

Introduction

This tutorial turns QBCore Events Reference into a clean, developer-friendly guide for QBCore/FiveM. You will follow a step-by-step flow, copy the relevant code patterns, and learn the “why” behind the setup.

Requirements

• QBCore installed and running on a dev server
• Basic Lua knowledge and comfort reading FiveM patterns
• A test workflow for iterating safely (dev server, not production)
• Optional: a code editor with Lua/FiveM helpers (VS Code recommended)

Step-by-Step Guide

Step 1: Player Events

In this step, you will apply the player events concept as a practical change: define the pieces, wire them together, then verify the behavior in your dev server.

Step 2: Client-Side Player Events

In this step, you will apply the client-side player events concept as a practical change: define the pieces, wire them together, then verify the behavior in your dev server.

Step 3: Server-Side Player Events

In this step, you will apply the server-side player events concept as a practical change: define the pieces, wire them together, then verify the behavior in your dev server.

Step 4: Job Events

In this step, you will apply the job events concept as a practical change: define the pieces, wire them together, then verify the behavior in your dev server.

Step 5: Job Update Events

In this step, you will apply the job update events concept as a practical change: define the pieces, wire them together, then verify the behavior in your dev server.

Step 6: Server-Side Job Events

In this step, you will apply the server-side job events concept as a practical change: define the pieces, wire them together, then verify the behavior in your dev server.

Step 7: Gang Events

In this step, you will apply the gang events concept as a practical change: define the pieces, wire them together, then verify the behavior in your dev server.

Step 8: Gang Update Events

In this step, you will apply the gang update events concept as a practical change: define the pieces, wire them together, then verify the behavior in your dev server.

Code Example

RegisterNetEvent('QBCore:Client:OnPlayerLoaded', function()
    local PlayerData = QBCore.Functions.GetPlayerData()
    print('Player loaded:', PlayerData.charinfo.firstname, PlayerData.charinfo.lastname)
    
    -- Initialize your script here
    -- Player data is now available
end)

Tips & Best Practices

• Keep authority on the server: validate inputs before money/database operations.
• Start with one resource/module at a time, then refactor after you verify it works.
• Use callbacks for request/response flows and events for push/UX updates.
• When you run loops, avoid freezes: always yield with Wait() (client/server) and cache hot values.
