[ANY] Prevent user name changes

Postby Zeus » Mon Dec 30, 2019 11:38 pm

I'm creating an plugin to integrate my discord with my TF2 servers; and want to force names to be sync'd. I need to be able to prevent players from changing their name.

This code does not seem to work:

Code: Select all

@PreEvent('player_changename')
def on_changename(event):
    return EventAction.BLOCK


Am I missing something?

Try something similar to what is being done in: https://github.com/Source-Python-Dev-Te ... cstrike.py

Syntax: Select all

@PreHook(get_virtual_function(engine_server, 'ClientCommand'))
def _pre_client_command(args):
"""Block name changes started by the server.
Pre-hook on IVEngineServer::ClientCommand to block the name changes.
"""
if args[2] == 'name "%s"':
return 0

it doesn't work because name it's client convar which he probably changes after Steam verification, and the server only requests it, the actual name change occurs in ClientSettingsChanged and call it pPlayer->SetPlayerName( pszName )

Syntax: Select all

ConVar	cl_name		( "name","unnamed", FCVAR_ARCHIVE | FCVAR_USERINFO | FCVAR_PRINTABLEONLY | FCVAR_SERVER_CAN_EXECUTE, "Current user name", CL_NameCvarChanged );

    client = Player.from_userid(args.get_int('userid'))
    client.set_name(args.get_string('oldname'))
    return EventAction.BLOCK

I understand correctly?

Yes, you are right, didn't notice the simple function :rolleyes:

No, this is possible, although I'm not sure, will only block a chat message, and he needs more global preventing.

Syntax: Select all

else if ( Q_strcmp( "player_changename", eventname ) == 0 )
{
if ( !hudChat )
return;

const char *pszOldName = event->GetString("oldname");
if ( PlayerNameNotSetYet(pszOldName) )
return;

wchar_t wszOldName[MAX_PLAYER_NAME_LENGTH];
g_pVGuiLocalize->ConvertANSIToUnicode( pszOldName, wszOldName, sizeof(wszOldName) );

wchar_t wszNewName[MAX_PLAYER_NAME_LENGTH];
g_pVGuiLocalize->ConvertANSIToUnicode( event->GetString( "newname" ), wszNewName, sizeof(wszNewName) );

wchar_t wszLocalized[100];
g_pVGuiLocalize->ConstructString( wszLocalized, sizeof( wszLocalized ), g_pVGuiLocalize->Find( "#game_player_changed_name" ), 2, wszOldName, wszNewName );

char szLocalized[100];
g_pVGuiLocalize->ConvertUnicodeToANSI( wszLocalized, szLocalized, sizeof(szLocalized) );

hudChat->Printf( CHAT_FILTER_NAMECHANGE, "%s", szLocalized );


What the... xD
I realized that he needed to block the player’s nickname change. I wrote test code that I haven’t tested (I have no way to test it)
I wrote code that should hide the change new nickname and return the old nickname. If you want more. What is stopping you? Write, study the code.

Oh my GOD. As I did not see this little function... xDD
Take offsets or signatures. And do not be challenging. I do not compete here, but only offer my own solution to the problem.

There is a leaked version of the Source Engine 2007, public Source SDK released by Valve and reverse engineered versions of the Source SDK.
