I'm getting the following error when trying to add an event listener in Hook_LevelInit in the Metamod:Source stub solution:

error C2355: 'this' : can only be referenced inside non-static member functions

Here's my function:

bool Hook_LevelInit(const char *pMapName, char const *pMapEntities, char const *pOldLevel, char const *pLandmarkName, bool loadGame, bool background)
{
	gameevents->AddListener(this, "player_death", true);

	return true;
}

Does anyone know what might be causing this?

Hook_levelinit should either be a member function of the class of your plugin or even better you should add the listener on plugin start

I was trying to use an example from the sample_mm solution. How would I add the listener on plugin start? Can you provide a little code snippet please? Thanks

I'm on mobile but just copy that gameevents line to the plugin start function where you get the interfaces

[Ajaxx]

So I moved the listener to the Load function like this:

bool StubPlugin::Load(PluginId id, ISmmAPI *ismm, char *error, size_t maxlen, bool late)
{
	PLUGIN_SAVEVARS();

	GET_V_IFACE_CURRENT(GetEngineFactory, engine, IVEngineServer, INTERFACEVERSION_VENGINESERVER);
	GET_V_IFACE_CURRENT(GetEngineFactory, gameevents, IGameEventManager2, INTERFACEVERSION_GAMEEVENTSMANAGER2);

	/* Make sure we build on MM:S 1.4 */
#if defined METAMOD_PLAPI_VERSION
	GET_V_IFACE_ANY(GetServerFactory, server, IServerGameDLL, INTERFACEVERSION_SERVERGAMEDLL);
#else
	GET_V_IFACE_ANY(serverFactory, server, IServerGameDLL, INTERFACEVERSION_SERVERGAMEDLL);
#endif

	SH_ADD_HOOK_MEMFUNC(IServerGameDLL, LevelInit, server, this, &StubPlugin::Hook_LevelInit, true);
	SH_ADD_HOOK_STATICFUNC(IServerGameDLL, ServerActivate, server, Hook_ServerActivate, true);

	gameevents->AddListener(this, "player_death", true);

	return true;
}

and I get the error:

error C2664: 'IGameEventManager2::AddListener' : cannot convert parameter 1 from 'StubPlugin *const ' to 'IGameEventListener2 *'

Do I need to instantiate a IGameEventListener2 and pass it to the listener?

[Zephyrus]

Nope, your class must extend the IGameEventListener2

class StubPlugin : public ISmmPlugin, public IGameEventListener2
{
}

By heart, but you should get the point

Thank you very much! That solved my issue with AddListener but now I get error:

error C2259: 'StubPlugin' : cannot instantiate abstract class

here:

StubPlugin g_StubPlugin;

You have to add all functions of the class to yours and make sure you include the header for the gameeventlistener class

[Ajaxx]

That did the trick. I was missing FireGameEvent. Thanks a million!
