Module 04 · Lesson 14

Crossing the wall: TriggerServerEvent and TriggerClientEvent

Last lesson was about events on one side. This lesson is about sending a message across the wall. The client asks. The server checks. The server answers the player who asked, and can also tell everyone else. That small pattern sits underneath many real FiveM features.

You'll learn: TriggerServerEvent -> TriggerClientEvent -> RegisterNetEvent -> the source variable -> one client vs all clients
Time: ~28 minutes
Prereqs: Lesson 13 (TriggerEvent) and Lesson 12 (trust & authority).
Outcome: A working ping-pong feature: client asks, server answers the one player who asked, and broadcasts a notice to everyone, with validation and authority intact.

BEFORE YOU START

Build it

Make the resource folder

The server has one folder for this lesson.

Inside your server's resources folder, create this folder:

code

resources/qu_trigger_server_client_event

Create the files

Every file named in the manifest exists.

Create this exact file layout:

code

resources/qu_trigger_server_client_event/
fxmanifest.lua
server.lua
client.lua
