Multiplayer Games

[samcp12]

So I recently started learning about Sockets and network programming in Java as I hope to add it into a game but I'm unsure how I would implement it, I was thinking of having it so you would type in the IP of the player you wish to connect to and then you would appear in the players "world", is this even possible or are there easier/more efficient ways? I am also curious how I would send player data, would I just use Object streams?

Sorry If I'm not being clear and sound like a newbie but I'm kind of new to networking

P.S
I've read the oracle tutorials/documentation and understand the basics of sockets/server sockets.

Depends an what you wan't to do.

If you just want to make a multiplayer game, use KryoNet (Its written like this I think).
If you want to learn how the networking works exactly: Don't use Object-Streams, as they are way too slow.

I for myself have my own networking library, but I think its better if you use a complete library like KryoNet,
since a complete library is more easy to use, cleaner, and mostly free of bugs.
(Don't get me wrong: Every library has its bugs, some are better, some are worse)

I hope I didn't confuse anyone with this post.
Any mistakes/fails/errors are due to 4 hours of work in the garden today.

I'd rather not use a libary, I prefer to know whats going on fully, unless I know exactly whats happening I just don't like using libarys.

Then the next question is: Do you wan't to use TCP or UDP?
There are many reasons to take the one or the other.
This thread here is a good read if you have to decide between them.

Have a nice day!

Thanks! I'll have a read of that

This is a ridiculous attitude to be taking as a programmer.  You're already using the Java standard library and it has hundreds of classes and features you didn't write, to say nothing of the big managed runtime it all sits on.  You can't make informed decisions about what libraries are appropriate and which you'd rather reimplement yourself if you don't get any experience in using them.

Now it's your code, so I don't really care in the end what you do, but communities also aren't usually inclined to help people who choose Not Invented Here as a guiding principle.  Just some unsolicited advice.

If I'm understanding the OP correctly he's trying to learn some networking basics, not create an MMO. I agree with you entirely that reinventing the wheel is usually not the smartest approach, but sometimes when trying to learn, it is good to understand everything that is going on, and then hand it over to the library for ease.

I understand where you are coming from but I didn't say I would NEVER use library I simply said I disliked the use of them, to further my point I should of said that I disliked the use of them when I don't understand the basics (not every single line of code). I guess it is just my attitude but I feel I should know a little about what is going on under the hood and not just blindly downloading a library without a single clue of what's going on.  Why shouldn't I learn a little bit of C before using something like OpenGl? It's my choice as a programmer, and besides how is gaining more knowledge in a subject a negative thing?

Back to the original topic, I was simply asking for advice for how Sockets can be used in game development, the library I was suggested to use is no where near what I will be needing any time soon. Like another poster said I am not looking to make some fancy MMORPG I was simply looking for advice.
