CreateThread / Citizen.CreateThread

Summary

Starts a new coroutine (thread) so code can loop and yield with Wait() without blocking the rest of the resource. The backbone of almost every FiveM script.

Returns

void

Parameters

Example

CreateThread(function()
  while true do
    Wait(1000) -- every second
    -- do periodic work
  end
end)

Common pitfalls

• Every loop needs a Wait() or it freezes the thread and causes hitches.
• Use separate threads for separate concerns instead of one giant loop.
• Wait(0) runs every frame; use larger intervals when you don't need per-frame updates.
