RegisterNetEvent

FiveM shared native documentation with a Lua example.

Summary

Registers an event that can be triggered across the network (client↔server). Required for any event triggered by TriggerServerEvent or TriggerClientEvent.

Returns

void

Parameters

eventNamestringThe network event name to register.
handlerfunctionOptional. The handler function (modern syntax registers it inline).

Example

-- Modern syntax (handler inline)
RegisterNetEvent('myscript:doThing', function(arg)
  -- runs when the event is triggered over the network
end)

-- source is available in server-side net events
RegisterNetEvent('myscript:serverThing', function(data)
  local src = source
end)

Common pitfalls

  • A plain AddEventHandler won't receive networked events — you must RegisterNetEvent for cross-network events.
  • On the server, always validate the caller and data — networked events are a common exploit surface.
