cancelEvent() not working for

[Lestat]

I want to prevent users being able to execute commands while not logged in. (The moment they are presented with the login screen).

  
function preventCommand(command) 
    if isGuestAccount(getPlayerAccount(source)) then 
        outputChatBox("Guest using command", source) 
        cancelEvent() 
    end 
end 
addEventHandler("onPlayerCommand", root, preventCommand) 
  

The above code succesfully cancels commands handled in the server. But it doesnt cancel commands handled in the client. Both prints the message in the chatbox.

Any workaround?

I would say; add a function in one of your files that gets executed when a player does a command at the client. If the function returns false, he'll cancel the command. MTA currently doesn't have onClientPlayerCommand event, sadly enough.
