MTA > Settings > Multiplayer > Nick:

[Xabache]

I need to force user nicknames (as visible in chat and on screen) to 4-10 characters, no color codes, in all caps. I know it is the mta client which defines the nickname you see despite the login panel account name, can I change this with my login_panel, or any other way?

[Et-win]

string.upper 
string.gsub 

[Xabache]

And could i implement these in my loginpanel_client.lua or loginpanel_server.lua, or is this an mta client change?

Those aren't functions they are lua strings. So you'd have to use them client side.

Those aren't functions they are lua strings. So you'd have to use them client side.

Who told you that? They're a lua string libary. Not a lua string but a function.

You can use them server or client. Available for both

[TrapLord Studios™]

Made a mistake thanks.

Ten years ago when i started mIRC scripting i found it most helpful when someone with skills came along and solved one or two problems in total. That I may learn from their example. As I have done for new mirc scripters ever after

The example I hope to learn from you from is an MTA New Player Regitration Entry nickname filter with hopefulyl all of the following rules forced at the entry point or rejected by the server once entered

- No Colored Nicks allowed #FFFFFF

- Characters A-Z, 0-9, - _ only

- 4-10 characters required/limited

- ALL CAPS

- A Profanity Nick name filter position would be nice too if (UCKYOU isin $nick) echo BAd Nickname ...sort of thing

Rejection at the typing level, the nickname entry level into the client would seem best, but a rejection message server side is also fine

Read about Lua's String Library. There are many ways you could achieve this, most commonly using patterns with regular expressions. You'll find lots of helpful answers if you use Google a bit.

For example if you searched the forums regarding colour-coded nicknames you'd find this popular line of code;

string.gsub(theString, "#%x%x%x%x%x%x", "") 
-- Can also be used like this; 
theString:gsub("#%x%x%x%x%x%x", "") 

Now you can use the above pattern with whichever string function you'd like to either prevent them from entering hex colour-codes or replace it.

You'll learn the most by trial and error and getting used to searching Google for potential hints in the right direction. People providing you full code/examples is but a lazy way to get someone to do it for you.

I've noticed that regardless my efforts nothing overwrites what is set in MTA > Settings > Multiplayer > Nick. Whatever is set in the MTA client is what i see in the chat room regardless of there being a totally different login name set on the client.lua side. Example: Xabache password as the client.lua login, is ignored and subject to ehcabaX as set in MTA > Settings > Multiplayer > Nick, and what i see on the map, above the user, and in the chat.

How do i force it to use client.lua Login nick only and ignore MTA > Settings > Multiplayer > Nick in all cases.

[Dealman]

You can use setPlayerName to change the players nickname temporarily.

Obviously, this will be reset to their default whenever they quit your server. This is a sort of security measure so servers can't "troll" people.

not working to force the login nick "a1" to appear on screen in chat as "A1" instead of the MTA client set nickname JohnDoe... setPlayerName( getLocalPlayer() , username)

..ideas?
