Re: Some errors
 
You define the engine interface pointer as *engine, then have m_Engine in your code. Change one or the other (I would recommend using just engine as its not a member).

DHJ 02-05-2009 15:56
Re: Some errors
 
ehh, like this "#define m_Engine *engine" in the top of the script without ""

Keeper 02-05-2009 16:01
Re: Some errors
 
No in your code ( Line 183 ) you use the pointer m_Engine, but you define the pointer to the engine as:
Code:
// Interfaces from the engine
IVEngineServer    *engine = NULL; // helper functions (messaging clients, loading content, making entities, running commands, etc)
Either change all the instances in your code from m_Engine to engine

or change the
Code:
IVEngineServer    *engine = NULL; // helper ...
to
Code:
IVEngineServer    *m_Engine = NULL; // helper ...

still got these errors, can someone explain how to fix them.

Re: Some errors
 
Can you repost your code in ampaste.net and add highlights to the lines its generating those errors on? (use @@ to the left of the lines to highlight)

Re: Some errors
 
I think the GetUnknown() is only a member of edict_t instead of IPlayerInfo. You would have to get the index of the player from the userid. Then use the edict_t * pEntity = engine->PEntityOfEntIndex(playerIndex);

DHJ 02-06-2009 14:20
Re: Some errors
 
ehm, can you give me an example?


i tried this
Code:
                edict_t * pEntity = engine->PEntityOfEntIndex(userid);
                pEntity->SetModel("models/player/skitz/ct_rank_private_v1/urban.mdl");

Keeper 02-06-2009 15:07
Re: Some errors
 
Here's what I use for finding the player index from userid. It might not be the best way, but it works :)

Code:
int PlayerIndex ( int userid ) {
    for (int index = 1; index <= g_iMaxPlayers;index ++) {
        IPlayerInfo *playerinfo = g_PlayerInfoManager->GetPlayerInfo( g_Engine->PEntityOfEntIndex(index) );
        if (playerinfo && (playerinfo->GetUserID() == userid)) {
            return index;
        }
    }
    return 0;
}
