I want to hook CBasePlayer::ObserverStart with Orpheu, since Okapi is having some issues especially on Linux and with virtual functions mostly, so I don't wanna use it at all anymore, as my server eprforms much betetr since I got rid of it.

Plugin test:

PHP Code:

#include <amxmodx>
#include <orpheu>

new const g_szPluginName[] = "Observer Spectator Test";
new const g_szPluginVersion[] = "1.0";
new const g_szPluginAuthor[] = "DarthMan";

new OrpheuFunction: g_hFuncStartObserver;
new OrpheuHook: g_hStartObserver;
const OrpheuInvalidHook = OrpheuHook: 0;

#define PLUGIN_NAME g_szPluginName
#define PLUGIN_VERSION g_szPluginVersion
#define PLUGIN_AUTHOR g_szPluginAuthor

public plugin_init()
{
    register_plugin(PLUGIN_NAME, PLUGIN_VERSION, PLUGIN_AUTHOR);

    RegisterForward();
}

public plugin_precache()
{
    g_hFuncStartObserver = OrpheuGetFunction("StartObserver", "CBasePlayer");
}

RegisterForward()
{
    if(g_hFuncStartObserver != OrpheuInvalidFunction)
    {
        if(g_hStartObserver == OrpheuInvalidHook)
        {
            g_hStartObserver = OrpheuRegisterHook(g_hFuncStartObserver, "OnPlayerSpectate_Post", OrpheuHookPost);
        }
    }
}

UnregisterForward()
{
    if(g_hStartObserver != OrpheuInvalidHook)
    {
        OrpheuUnregisterHook(g_hStartObserver);
    }
}

public plugin_unpause()
{
    RegisterForward();
}

public plugin_pause()
{
    UnregisterForward();
}

public plugin_end()
{
    UnregisterForward();
}

public OnPlayerSpectate_Post(const iID)
{
    new szPlayerName[32];

    get_user_name(iID, szPlayerName, charsmax(szPlayerName));

    server_print("%s joined team 'SPECTATORS'.", szPlayerName);

    new iPlayers[32], iPlayer, iNum;

    get_players(iPlayers, iNum);

    if(iNum > 1)
    {
        for(new i = 0; i < iNum; i++)
        {
            iPlayer = iPlayers[i];

            if(iPlayer != iID)
            {
                client_print(iPlayer, print_chat, "* %s joined team 'SPECTATORS'.", szPlayerName);
            }
        }
    }
} 


Signature file:

PHP Code:

{ 
    "name" : "StartObserver", 
    "class" : "CBasePlayer",
    "library" : "mod", 
    "arguments" : 
    [ 
        { 
            "type" : "Vector"
        },
        { 
            "type" : "Vector"
        }
    ], 
    "identifiers" :
    [
        {
            "os" : "windows",
            "mod" : "tfc",
            "value" : [0x53,0x56,0x8B,"*",0x57,0x33,"*",0x8B,"*","*",0x57,0x83,"*","*",0x50,0x6A]
        },
        {
            "os" : "linux",
            "mod" : "tfc",
            "value" : "_ZN11CBasePlayer13StartObserverE6VectorS0_"
        }
    ]
    
} 


The funcion has Params as Vectos as args as per HLSDK. So, is there a way I can hook it with Orpheu?
