[Solved] How to intercept text entered in console?

Dragokas · **Author**

Hi,

what function should I detour to have ability to catch (and ideally, modify) my own entered text in game console ~, like "aaaaaaaaaaaaaa":

Quote:

] aaaaaaaaaaaaaa
Unknown command "aaaaaaaaaaaaaa"

I want replace with other text before game and sm search for existance of appropriate command.

Or at least catch it.

Thank you.

Similar to a registered command, this global callback will catch a majority of commands and allows for returns.

Code:

public Action OnClientCommand(int client, int args)
{
	char cmd[64];
	GetCmdArg(0,cmd,sizeof(cmd));
	if (StrContains(cmd,"aaa",false) == 0)
	{
		PrintToConsole(client,"%s not registered, but there is another similar command named <aabbcc>.",cmd);
		return Plugin_Handled;
	}
	return Plugin_Continue;
}

While it won't catch a lot of client-side commands, a majority of the unregistered commands will. You might just have to test to see if it can do what you want it to.

Ouuuuu, that is exactly what I want. Thanks for let me know.

And, damn it, Valve doesn't support cyrillic letters in console when the arey at 0 argument.

Always return srange 0xD0. So, looks like still required to go deep in low-level.

Just put a null terminator at the beginning of the string of the reply message?

You should beable to use this as a base to change cmds.

It looks like he hooks for "ClientPrintf ... function, intended to print console text.

I think that can't help me because in my case valve already broke that text.

I need to hook previous function that accept my text before handling and answering me in console.

Anyway, thanks for help.

Ahh i see, you may wanna look at where sm does cmd listeners or the OnClientCmd func ect

https://github.com/alliedmodders/sou...pp#L1128-L1240

or move the "sm" cmd check below allow sourcemod plugins to change stuff before anywhere else and build sm with your change.

Thanks, I lookup vice versa call chain.

I leave it here for myself.

sm:

PHP Code:


			
IServerGameClients *serverClients = NULL;
...
GET_V_IFACE_CURRENT(GetServerFactory, serverClients, IServerGameClients, INTERFACEVERSION_SERVERGAMECLIENTS);
...
SH_DECL_HOOK2_void(IServerGameClients, ClientCommand, SH_NOATTRIB, 0, edict_t *, const CCommand &);
...
SH_ADD_HOOK(IServerGameClients, ClientCommand, serverClients, SH_MEMBER(this, &PlayerManager::OnClientCommand), false);

Valve SDK:

PHP Code:


			
EXPOSE_SINGLE_INTERFACE_GLOBALVAR(CServerGameClients, IServerGameClients, INTERFACEVERSION_SERVERGAMECLIENTS, g_ServerGameClients );

Problem should be somewhere here:

https://github.com/VSES/SourceEngine...face.cpp#L2367

PHP Code:


			
void CServerGameClients::ClientCommand( edict_t *pEntity, const CCommand &args )
{
    CBasePlayer *pPlayer = ToBasePlayer( GetContainingEntity( pEntity ) );
    ::ClientCommand( pPlayer, args );
}

https://github.com/VSES/SourceEngine...e/cmd.cpp#L765

PHP Code:


			
const ConCommandBase *Cmd_ExecuteCommand( const CCommand &command, cmd_source_t src, int nClientSlot )

https://github.com/VSES/SourceEngine...lient.cpp#L995

PHP Code:


			
bool CGameClient::ExecuteStringCommand( const char *pCommandString )

Some sigs from L4D2 linux:

Solved. Perhaps, it is a SourceMod bug: https://github.com/alliedmodders/sourcemod/issues/1248
