TriggerEvent: how scripts talk to each other

Make the resource folder

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

resources/qu_trigger_event

Create the files

Create this exact file layout:

resources/qu_trigger_event/
fxmanifest.lua
client.lua

Write fxmanifest.lua

Open fxmanifest.lua and paste this:

fx_version 'cerulean'
game 'gta5'

client_script 'client.lua'

No lua54 'yes' line. As of June 2025 that directive is deprecated and you no longer need to enable it: Lua 5.3 has been deprecated and every Lua script now runs on Lua 5.4 automatically, so you leave it out.

Write the lesson code

Open client.lua and paste this. Two handlers listen for the same event name, and one command fires that event:

AddEventHandler('qu_trigger_event:shout', function(message)
print('[qu_trigger_event] handler one ' .. message)
end)

AddEventHandler('qu_trigger_event:shout', function(message)
print('[qu_trigger_event] handler two ' .. message)
end)

RegisterCommand('shout', function(_, args)
TriggerEvent('qu_trigger_event:shout', table.concat(args, ' '))
end, false)

Start and test it

Open server.cfg and add this line:

ensure qu_trigger_event

Save, then run:

restart qu_trigger_event

This is a client_script, so the command runs from inside the game. Run /shout hello in chat, or type shout hello without a slash in F8.

Chat: /shout hello
F8: shout hello
