Creating New Entity Type

batterytime · **Author**

How would I go about coding a new entity type? I'm pretty experienced on how to use the Source SDK, and would like to create a new entity type. I can do this easily in the SDK, but how would I get it into an extension/MetaMod plugin? Like, if I had a new class I made with the two files CMyCustomObject.h and CMyCustomObject.cpp, how could I get it to work with a mod?

Also, once it was put into the game, how would I spawn one of that item into the world?

Thanks,
Batterytime

That would be exactly the same as how you'd do it in the SDK. MM:S simply adds some useful stuff, like SourceHook.

?

It's very difficult to do this. Since MM:S is server-side you can't introduce new code on the client and you can't modify the property networking tables. And since most games are closed-source and binary incompatible with SDK internals, you can't trivially derive from CBaseEntity anyway.

The best you can do is introduce tons of hooks on an existing CBaseEntity derivation, piggy-backing off another entity to introduce new server-side logic.

pRED could give you more examples.

Well, I don't believe it has to be as complicated as that, since the "entity" I want to make only has to sit on the server side. It's not even supposed to be visible to other players. Would this be possible?

Have a look at my CEntity framework (It requires SourceMod

)

It's just an abstraction of BAILOPAN's suggestion designed to look as close to normal SDK coding as possible (still a work in progress - use at your own risk).
I've got an updated (read: unstable and fundamentally broken) version sitting half completed locally that contains more code to allow creating new entity names. Let me know if you want to try that.

Hehehe, pRED, I've actually looked at your framework. However, I'm really new to this, so I'm pretty confused by how this entire SourceMod/MetaMod system works. All I want is to be able to define my own entity with a Think function, and some local variables stored in it. Can your new CEntity framework work?
