Item Use Effect - QBCore Guide for FiveM

Introduction

This tutorial turns Item Use Effect 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: Define the item

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

Step 2: Register use effect

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

Step 3: Verification

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

Step 4: See also

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

Step 5: Next steps

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

Code Example

['coffee'] = {
  label = 'Coffee',
  weight = 200,
  stack = true,
  close = true,
  description = 'Keeps you awake'
}

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.
