-Put PM's say hook code in a header file, sayhook.h
-Declare g_pICvar as an extern
-Include sayhook.h in my plugin's cpp file
-Declare an object of type CSayHook

From here I do a make and everything compiles fine. But, when I try to load my plugin the server console just says "Unable to load plugin". If I comment out the line where I declare the CSayHook object and recompile, the plugin loads fine.

I must be overlooking something obvious but I'm at a loss. Any suggestions?

Hi, i'm having the same trouble with my plugin, when i tried to hook convar. everything compiles fine (i have convar.o) but the same error "Unable to load plugin", somebody have a solution..

i used XAD's code .. (run correctly with windows

)

As you have probably noticed, doing a CON_COMMAND_F("say", FCVAR_GAMEDLL) makes the original command completly disappear. So, this is what I came up with:

Code:

// Special hook for say commands
class CSayHook : public ConCommand
{
	// This will hold the pointer original gamedll say command
	ConCommand *m_pGameDLLSayCommand;
public:
	CSayHook() : ConCommand("say", NULL, "say messages", FCVAR_GAMEDLL), m_pGameDLLSayCommand(NULL)
	{ }

	// Override Init
	void Init()
	{
		// Try to find the gamedll say command
		ConCommandBase *pPtr = g_pICvar->GetCommands();
		while (pPtr)
		{
			if (pPtr != this && pPtr->IsCommand() && strcmp(pPtr->GetName(), "say") == 0)
				break;
			// Nasty
			pPtr = const_cast<ConCommandBase*>(pPtr->GetNext());
		}
		if (!pPtr)
			OMGOMGOMG ! PRINT ERROR1!1!1!!!!

		m_pGameDLLSayCommand = pPtr;

		// Call base class' init function
		ConCommand::Init();
	}

	void Dispatch()
	{
		// Do the normal stuff, return if you want to override the say

		// Forward to gamedll
		m_pGameDLLSayCommand->Dispatch();
	}
};

// Don't forget to make an instance
CSayHook g_SayHook;

(almost copy & paste from sourcemod)

EDIT: Fixed. Forgot m_pGameDLLSayCommand = pPtr; Thanks to u/d/theqizmo for reporting this

Wow this is exactly what Iwas looking for. But the part you edited did not compile because you forgot to convert it to a ConCommand. This do the job:

m_pGameDLLSayCommand = (ConCommand *)pPtr;

Thank for posting this, very much appreciated
