Some optimizations were made into dll, for each entity classname the game creates a hash -> all ents are cached, the new entities created by amxx are not taken into account.

Type in server console print_ent command.

Generaly this is not a problem, but when you are creating a weaponbox or item_armoury the problems start. The first one doesn't get removed on new round and the other one doesn't respawn on new round. Without that utility removing and respawning manually is needed.
This method is cs specific, because in cs we have a function called CREATE_NAMED_ENTITY which calls the engine function pfnCreateNamedEntity and also AddEntityHashValue.

FM/Engine's functions which create entities doesn't call AddEntityHashValue. A possible solution may be to hook AddEntityHashValue with orpheu/okapi and make our custom entity to be taken into accout.

Anyway, now I come with a better solution, by hooking CREATE_NAMED_ENTITY. This will do the trick, allow us to have our custom ents taken into accout without extra code, and all the job is done by game. In most of cases it's better to let the game to work for you.

I've create a native create_named_entity which only needs a class name and will return a completly valid entity which you can use.


You need orpheu for that plugin to run and you also need to include create_named_entity.inc in your plugin.

A short example:

/* Plugin generated by AMXX-Studio */

#include <amxmodx>
#include <fakemeta>
#include <create_named_entity>

new const Model[] = "models/w_weaponbox.mdl"
public something()
{
    new iEnt = create_named_entity("weaponbox")
    if(!pev_valid(iEnt))
    {
        return
    }
    
    //set an origin by yourself
    engfunc(EngFunc_SetModel, iEnt, Model)
    engfunc(EngFunc_SetSize, iEnt, Float:{0.0, 0.0, 0.0} , Float:{0.0, 0.0, 0.0})
    
    set_pev(iEnt, pev_movetype, MOVETYPE_TOSS)
    set_pev(iEnt, pev_solid, SOLID_TRIGGER)
    
    
    dllfunc(DLLFunc_Spawn, iEnt)
}

The only thing that is different is:

create_named_entity("classname")

I'm going to leave here the needed game code:

PHP Code:

edict_t *CREATE_NAMED_ENTITY(string_t iClass)
{
    edict_t *named = g_engfuncs.pfnCreateNamedEntity(iClass);

    if (named)
    {
        AddEntityHashValue(&named->v, STRING(iClass), CLASSNAME);
    }

    return named;
} 


The point is to see that it calls AddEntityHashValue

As you probably know

Likely almost no one. That's not really common knowledge. This might be a good idea to explain the whole thing.

is cs specific

Please make the thread more obvious about this, like a tag or similar. It will help when people will search.

It's always good to work with the game and not to re-create stuffs, for compatibility purpose.

You should elaborate a bit more as it's a general sentence out of context. Here the advantage of calling CREATE_NAMED_ENTITY is simply that the games will call itself pfnCreateNamedEntity and since sent from game, any plugins/modules will be able to hook your custom entity creation.


As side-note, it's probably not a good idea to allocate each time a string with Engfunc_AllocString because even for a same string, it will allocate a new one and memory is kept until you shutdown HLDS. For plugin creating a lot of entities this could be a nice waste of memory. Unfortunately, we have not really the choice from a pawn plugin. This could be lowered by caching the value though.

Will add CS native for that, as it's quite useful.

You may add it, but until you do, it's usefull to have this plugin..

[Arkshine]

I don't see where I did say that plugin was useless?

[HamletEagle]

No, I mean that I created this because I needed it and I'll keep it here until you add that native

1. This isn't something recent. You can check older cs versions and they have print_ent command and AddEntityHashValue functions on it.
2. Before this thread Arkshine said it was going to add it to cstrike module :v

1. I know, where I say that this is something new ?
2. He didn't added it yet, anyway I'm using it for one of my projects so I thought it worth to share.

Nice job, could be useful in my next mod.
