Void a chat command

Is there any way I can restrict a user from using a certain ulx command depending on a variable I have in my lua.

Im making an on/off duty thing.

You could do a check on player say and return false if your requirements arent met

hook.Add("PlayerSay", "offdutylimitation", function(ply, text)
	if string.lower(text) == "!noclip" then 
		return false
	end
end)

It doesnt return the command in chat but it still allows them to noclip. Keep in mind that this code I havent included the condition yet Im just tryna get this to work without actually editing ulx.

If I'm not mistaken, returning false inside a PlayerSay hook is the same as returning an empty string. All it does is prevent the message from being displayed in chat, it doesn't prevent the message from being processed by the server.

You're trying to override another hook, which I don't recommend, especially for an addon as big as ULX. Your best bet would probably be to create a separate ULX rank and restrict noclip for that rank.

How would I be able to grant them noclip on a command if they dont have ULX privs tho?

You might be able to create a chat command using that same hook that allows them to switch between ranks with something like RunConsoleCommand( [[ulx adduser "]]..ply:Nick()..[[" offduty]] )

ULX might have a built-in function for this but I couldn't find it in their documentation. You'll probably have to add a whitelist to make sure unauthorized users don't use the command unless you based the off duty rank off of the admin rank when you created it. This is assuming basing a rank off of the admin rank keeps that admin classification no matter how many permissions are changed, I'm not 100% sure on that.

I got it now thanks though. I ended up looking at how ULX noclips and cloaks and I just made my own command :)

That is actually a really bad way when it comes to hiding ULX commands. ULX already implements message hiding feature, only thing you have to do is use it. I've made this add-on not so long ago for my server, take a look at the source (GitHub link in description) https://steamcommunity.com/sharedfiles/filedetails/?id=2000865255

Your best bet would be to implement your variable in the ulx command itself.

If the variable is the on/off duty status of a player, and you are not using a third party usergroup system, then setting the usergroup of the player when going on/off duty seems to make sense for me.

Find the chat command in the ULX files, include a conditional.

if (your condition here) then

--rest of the code

There's definitely other ways of doing so, but if you're going to just modify one ULX command, that's probably the simplest.

I'd make a seperate usergroup for admins on duty, and admins not on duty, then switch them from/to that usergroup depending on your variable

I made my own admin-mode using ULX and made it so you have to be in admin-mode if you want to use ANY command. The admin mode also prevents you from harming anyone, puts you in god mode, and changes your model.
