Delay server shutdown or stop servers' quit command from working?

FiveM Server Development Server Discussion

What I want to achieve:

A more graceful server shutdown procedure, meaning all resources have time to save, log, update and do other miscellaneous tasks before the server is allowed to shut down. I don’t want to change anything on the clients’ side.


What I’ve tried so far:

I have created a custom exit command which executes the quit command once all resources are ready.

Simple example 
RegisterCommand("exit", function(source, args, rawCommand)
	local _source = source
	if _source == 0 then
		--[[
			Functions to update the server status,
			log the time and maybe args too,
			give players a 15-30s warning, etc.
		]]

		ExecuteCommand("quit")
	end
end)

Note: Requires add_ace resource.name command.quit allow

After that I tried adding an ace to system.console, denying the quit permission in case I enter quit out of muscle memory, hoping that the resource would still be allowed to execute the command, but that didn’t work out.

I also tried using the onResourceStop and onServerResourceStop events, but those only report after a resource has already stopped, unless I missed something.


My questions:

  • Is there a better solution, eg. executing quit and the server will wait for everything to finish?
  • If the above isn’t possible, maybe blocking the quit command from being executed in the console window so I, and perhaps others, can’t accidentally use the wrong procedure due to muscle memory?
  • Or did I completely miss an event or a function that could help me out here?

Little side-note: I’m not using txAdmin, meaning that I won’t have to modify it.

Thanks in advance for any help and tips!
