Hi guys,

I was wondering if there was an easy way in a SourceMod extension to find an entity by its classname and adjust its properties. This would be quite easy to do in a plugin, but unfortunately, the rest of my logic is already in an extension.

Incidentally, the entity class is vote_controller, and the properties I want to adjust are:

 -Member: m_iActiveIssueIndex (offset 796) (type integer) (bits 32)
 -Member: m_iOnlyTeamToVote (offset 800) (type integer) (bits 32)
  Sub-Class Table (2 Deep): m_nVoteOptionCount
  -Member: 000 (offset 0) (type integer) (bits 8)
  -Member: 001 (offset 4) (type integer) (bits 8)
  -Member: 002 (offset 8) (type integer) (bits 8)
  -Member: 003 (offset 12) (type integer) (bits 8)
  -Member: 004 (offset 16) (type integer) (bits 8)
 -Member: m_nPotentialVotes (offset 824) (type integer) (bits 32)
 -Member: m_bIsYesNoVote (offset 828) (type integer) (bits 1)

(yes, all of them)

For FEBC, you can copy the native implementation using IServerTools right out of SDK Tools.
http://hg.alliedmods.net/sourcemod-c...tives.cpp#l638

For finding datadesc property offsets and values, use GetDataMap and FindInDataMap on IGameHelpers.

PHP Code:

datamap_t *pMap = gamehelpers->GetDataMap(pEntity);
typedescription_t *td = gamehelpers->FindInDataMap(pMap, "m_nVoteOptionCount");
uint32 nVoteOptionCount = *(uint32 *)((intptr_t)pEntity + GetTypeDescOffs(td));

These are Netprops by the way, would this still be the correct way to access them?

Actually, they exist as both. I sillily search for vote_controller instead of CVoteController in the netprop dump, ofc didn't find it, and then looked in the datamap dump.

Netprops, specifically for integers are a little trickier due to the varying bit counts.

Look at SM's core/smn_entities.cpp and GetEntProp for an example.

Hey, sorry to bump this since I'm trying to do the same thing

can you tell me why this doesnt work ?

PHP Code:

CBaseEntity *UTIL_FindEntityByClassname(int start, const char *pEntityClassname)
{
    CBaseEntity *pEntity;

    if (start == -1)
    {
        pEntity = (CBaseEntity *)g_pServerTools->FirstEntity();
    }
    else
    {
        pEntity = gamehelpers->ReferenceToEntity(start);

        if (pEntity)
        {
            pEntity = (CBaseEntity *)g_pServerTools->NextEntity(pEntity);
        }
    }

    if (pEntity)
    {
        static int offset = -1;

        if (offset == -1)
        {
            sm_datatable_info_t info;

            if (gamehelpers->FindDataMapInfo(gamehelpers->GetDataMap(pEntity), "m_iClassname", &info))
            {
                offset = info.actual_offset;
            }
        }

        const char *pClassname;
        string_t str;

        int lastLetter;

        while (pEntity)
        {
            str = *(string_t *)((uint8_t *)pEntity + offset);

            if (str == NULL_STRING)
            {
                pEntity = (CBaseEntity *)g_pServerTools->NextEntity(pEntity);
                continue;
            }

            pClassname = STRING(str);

            lastLetter = strlen(pEntityClassname) - 1;

            if (pEntityClassname[lastLetter] == '*' && !strncasecmp(pEntityClassname, pClassname, lastLetter))
            {
                return pEntity;
            }
            else if (!strcasecmp(pEntityClassname, pClassname))
            {
                return pEntity;
            }

            pEntity = (CBaseEntity *)g_pServerTools->NextEntity(pEntity);
        }
    }

    return pEntity;
}; 


Basically I'm trying to find the fov ("ent_fov_controller") and edit it also is there any equivalent to SetVariant* and AcceptEntityInput

PHP Code:

void OnServer_Activate(edict_t *pEdict, int edictCount, int clientMax)
{
    engine->LightStyle(0, MAP_LIGHT);

/*
    CBaseEntity *pFogEntity = UTIL_FindEntityByClassname(-1, "env_fog_controller");

    if (!pFogEntity)
    {
        g_pServerTools->DispatchSpawn(pFogEntity);
    }

    g_pServerTools->SetKeyValue(pFogEntity, "fogmaxdensity", 0.6);
    
    SetVariantInt(FogStartDist);
    AcceptEntityInput(FogControllerIndex, "SetStartDist");
        
    SetVariantInt(FogEndDist);
    AcceptEntityInput(FogControllerIndex, "SetEndDist");
    
    SetVariantInt(FogZPlane);
    AcceptEntityInput(FogControllerIndex, "SetFarZ");

    SetVariantString(FogColor);
    AcceptEntityInput(FogControllerIndex, "SetColor");

    SetVariantString(FogColor);
    AcceptEntityInput(FogControllerIndex, "SetColorSecondary");
    
    SET START DIST, END DIST, FARZ
*/
} 


The lightning works fine, but others doesnt
