Client-Server Data Traffic Concepts

[poste9]

Hello everyone,

 

Im completelly new to this mc modding area but I would really appreciate if you guys keep reading after I've made that statement. 

 

My name is Rafael and I'm from Brazil, I work with c++ for quite sometime now (28 years old - yea I'm too old for mc, I know) and I have a littlebit of a telecom development background. (voip)

 

I was thinking about what to do to get me started with modding and realize that every mod I asked about having voice capabilities uses somekind of an external software to make it work.

 

I want first to share my ideas so you can understand what I want and will do.

 

(Ok, this is gonna be a big post, but please read it all)

 

I looked into the basic concepts about modding for minecraft and I'm kind of amazed how easy you guys made it for us.

I went down and tested a couple of objects and it really works fine.

 

If this thing keeps going like I plan to do, this might be a really big mod, but also can drastically improve the gameplay of this awesome game. (Dont need to keep saying... I really know I'm too old for this.. but hey.. I enjoy it ok?)

 

First thing: The basic idea is to enable voice capabilites to the game and everything that comes with it.

 

Here are the features I could think about in order of development.

 

- A Player talk and other players around could hear.

- Players would talk and the enviroment around it would affect the output of the voice.

- Voice commands (maybe) : this would enable integration with other mods.

 

This 3 stuffs being done, would enable some other possibilites like:

 

- Microphone item

- Broadcast block

- Something like a radio station multiblock

- Radio output block

- Etc...

 

Even came to my mind some kind of survaillance thing going on, but I can't think of good way to record... maybe I could think about it in the future after I get involved.

 

Well... now that you understand what's going on, Let's go to the question already.

 

I started making some coding and it would be really helpfull if you guys could make some clarifications for me before I go deep on this thing.

 

Can I hook up the very first function that receives data ? It would be nice to just intercept the stream buffer before it get parsed and If my mod handle it, parse it, and propagate in the propper way to rest of the engine whats going on.

 

I think it should be better if I dont have to listen in another port for audio data because I it would be kinda hard to make all the security and session stuff without using the core of the minecraft.

 

 

I think thats all for now... I hope I made myself clear.

 

Thank you in advance

As to your question:

"Can I hook up the very first function that receives data ?"

What do you mean by that? Intercepting packets?

 

As to personal experience and idea - this is totally possible and was alredy made in past (idk if updated now).

If I remember correctly it was a mumble-based mod that connected world, players to mumble engine and you could talk in-game (yeah, with all that distance stuff).

Why Mumble - it is open source and VERY GOOD at compressing voice, which when you have server with a lot of players is like SUPER important.

 

As to personal experience - since mod mentioned (at that time) required mumble client and server somewhere running in background (it was more cross-application), my friend and I wanted to rewrite whole engine and place it into MC client mod and MC server mod.

Long story short - had something working but there was so many unaccounted for errors that project slipped into abyss.

 

Well, a lot of useless talking - but yeah, I do recommend using mumble voice engine.

Thank you for your response and suggestion.

 

But I really want to make something from scratch.

 

My last resource would be to make a SIP server(maybe PJSIP) and authenticate users based on mc auth data.

I have a solid knowledge about how compression works, so I would not use a mumble engine just to make this thing easier.

 

Also I would probabbly be limmited to what I could do because I THINK there would be no reason for the mumble engine be made for this kind of sittuation.

 

But ye, I have a softphone of my own and I know how hard it can be.

 

Thank you again.
