Enable AlertMessage_Post to hook Round Start & Round End.

Enable MessageBegin to hook Messages

Code:

void OnMessageBegin(int Dest, int Type, const float *pOrigin, edict_t *pPlayer)

{

        switch (Type)

        {

        case MESSAGE_HOSTAGEK:

                Ibreak;

        case MESSAGE_HOSTAGEPOS:

                break;

then you need to hook WriteByte, WriteCoord etc.. + MessageEnd forwards.

then you need to create bool array where you will which message arguments are you getting from forward WriteXXXX.

Code:

bool MessageHooked[256];

Lets hook health message & get argument (1 Byte Argument) (https://wiki.alliedmods.net/Half-life_1_game_events)

Code:

#define MESSAGE_HEALTH 70



void OnMessageBegin(int Dest, int Type, const float *pOrigin, edict_t *pPlayer)

{

        switch (Type)

        {

        case MESSAGE_HEALTH:

        {

                MessageHooked[MESSAGE_HEALTH] = true;

                RETURN_META(MRES_IGNORED);

        }

        }



        RETURN_META(MRES_IGNORED);

}



void OnWriteByte(int Value)

{

        if (MessageHooked[MESSAGE_HEALTH])

        {

                // First Value = health

                // Wanna Change IT?

                // then do like this

                WRITE_BYTE(Value * 2);

                RETURN_META(MRES_SUPERCEDE);

        }



        RETURN_META(MRES_IGNORED);

}



void OnMessageEnd(void)

{

        MessageHooked[MESSAGE_HEALTH] = false;

        RETURN_META(MRES_IGNORED);

}

didnt checked this code, but must work.
ofc you must hook those forwards with g_pengfuncsTable;

Re: hooking game start or messages

u r smart but what is g_pengfuncTable ?

enginefuncs_t *g_pengfuncsTable this is engine function hooker. you can hook with this engine functions. this is created in amxmodule.cpp/meta_api.cpp. and you can use this with extern:

Code:

extern enginefuncs_t *g_pengfuncsTable;

better hook functions earlier at starting server. theres also g_pengfuncsTable_Post variable, which hooks same functions but after this function is called (Post).

example of hooking PrecacheModel

Code:

int OnPrecacheModel_Post(const char *Resource)

{

        <Your Code Here>

        

        <Wanna Block Precache?, then use RETURN_META_VALUE(MRES_SUPERCEDE, NULL);>

        // ^^ Not tested but think must work

}



void <Function where you want to set hook for engine functions>(void)

{

g_pengfuncsTable_Post->pfnPrecacheModel = OnPrecacheModel_Post;

}
