Gaia Emulator - Java - Gradle

Howdy folks,

Today I present you with a project I've been working on for a while now.

I started working on it because I was bored and needed something to do, as AzureJava was discontinued (due to the lack of enthusiasm and updates) and the name got on my nerves, due to my O.C.D when coding high-level OOP languages.

I know what you're going to say, "This is just a copy of AzureJava" --- nothing like it. AzureJava was my first Java Emulator from scratch and I hope you can understand that, your first experience is not always going to be your best, it's not always going to *click* the first time around.

Gaia is to my standards (beware of my O.C.D) clean, documented, and I'd go ahead and say the methods practice is pretty good as well, if you get what I'm trying to say? I don't know how else I would be able to assure you on the fact that I focus on the slightest of detail, from classes I don't have any business being in, look at the GitHub log, random commits titled "Naming Conventions" because that's how I roll

:junglejane:

List of dependencies & frameworks used:

• Netty 4 for it's networking. To specify, our networking component basically consist of a TCP Server and an RCON/MUS Server (RCON is not done yet).
• Hibernate ORM along with java.persistence annotations, used for easily querying known database tables.
• Trove for high performance collections
• Log4j Logging of course!
• Reflections class searching for packet registration
• HikariCP connection pooling
• Guice dependency injection
• Governator Guice extensions
• MappedBus low latency interprocess communication (IPC) library used for sharing memory across the JVM. Will go into more detail on that keep reading!

The software design for my emulator was inspired by Scott and Jordan. Somewhat Microservice Architecture, with touches by moi.

Diagram I wrote up along time ago: http://i.imgur.com/yfwIlNU.png

• The workers are basically separate processes from the master
• This increases the scalability of the overall application, thus quickly fixing errors without restarting the whole hotel.
• For example: Navigator runs on a separate process and crashes... just the navigator will go down, and it can be easily worked on and restarted without the users even noticing.
• This improves the stability of the master application because if you think about it, it's basically load-balancing, which avoids the master from performing vast, strenuous calculations.

Positive and negative feedback appreciated! Open source, so if you feel like you could contribute to the development, go ahead!

P.S.
Don't talk shit about how I won't finish my project, at least I'll be providing you with a "good" OPEN SOURCE base to work off of?

@Caustik (Adil) one of my best mates, help and support along the way!
@scottstamp851 (Scott) i know we've had a falling out, but your cool man! thanks for the help and encouragement.
@Quackster (Alex) encouraging me?? kinda? x's and o's!
@maritnmine (Martin?) i don't know you personally, but you've helped me a lot through the years with your somewhat educational posts i.e. Guide on writing a Habbo Emulator.

Thinking about whether I should use a Scripting Engine (Lua?) to load and interpret plugins, or using JAR files, hoping the plugin manager will be committed tonight, currently leaning in the direction of JAR files.

Looks like the most promising project I have seen for a while. But I must ask, what about dependency injection?

Thanks. I'm new to dependency injection but I'm currently using it to create an instance of a class without having to assigning values that wouldn't be used by the suggested caller. Only 1 class uses it at the moment, which happens to be the main class.

Singleton classes with "default values" are also in mind.

Governator is a set of extensions for Guice :p. Also, hibernate may trouble you when you're a bit deeper into the project, so make sure you read up on plenty of documentation.
Looks promising, good luck!

You use dependency injection (DI) to make your objects/modules depend on less modules. That way it is far easier to test. If for example your class relies on a call to a static method, it has one dependency to that part. Therefore your "unit tests" would become more like integration tests when you are writing your tests to that class. This is also why the traditional way of implementing singleton classes in Java is considered as evil.

Thanks for the suggestion, I'll look into it!

O.C.D kicked in yesterday night, cleaning up some of the older class files.

Sorry I didn't commit the plugin manager yet, nor did I finish working to get the client to load (still thinking of revisions). I wasn't planning on using an encryption, so I was just going to go to the same build Mango used, with the banner.php.

In other news, I've been "thinking" of removing the configuration file, and allowing the user to configure the emulator via database.

Only if everything could be solved with a "Fix it!" button.

And how about both? Just like Arcturus, key configuration values like database, gameserver in the config file and all other less important things (read default values) in the database. :P:

Fields that are static final/const should be all uppercase :^)
Btw, I see that you are writing a lot of documentation. Like a lot. Make sure that the documentation is short and that you don't have too much bloat in it. If there is something in the documentation that doesn't contribute to the reader's understanding of it, I suggest leave it out. Not sure if you are going to make a whole lot of changes to the code (As this is early in the development stages), there could be major changes that could have a significant impact on the documentation writing and you would have to re-write much of the documentation that you already put a lot of effort into. Might wanna look for a good balance there.

Thanks for the feedback, I'll try to make it as short and as simple as possible.

Lol, since I cannot say this development looks good since that's off topic I might try it again:

Looking good. Cannot wait for some screens. This development surely looks promising!

Thanks. I'm really not focusing on getting the client up until I'm satisfied with every other initialization component within the emulator. In other news... I've just started rewriting the Configuration Manager. Check out the commits: https://github.com/HeyItsKawaii/Gaia.../configuration

Finished HikariCP and Hibernate https://github.com/HeyItsKawaii/Gaia...aiaServer.java

Heh. So, it's not "just AzureJava", but it's literally the same codebase with most of the objects renamed?

Interesting to see you couldn't figure out the correct way to implement the configuration bootstrapping I "borrowed" from Crowley.

Sorry guys. This is old news.

I don't know what you're talking about, and no it's not the same codebase, I'm not going to argue with you though.

I don't see why you try to take credit for my work, and AzureJava, you REFACTORED my code, which I fail to brag until now.

http://prnt.sc/a2lpay The proof is in the pudding.

The real reason I quit? and everyone else quit? because a so called member of our team failed to respect another member of the team (no names). He/She also tries to take credit for writing what he/she did not write, as well as kiss ass to TheGeneral (from my point of view at least).

As suggested on Skype, pudding cup #2.

Wow the Github Repo is Horrible!

Please add to your Gitignore Local user Files!

All the Binaries was Included and Also IntelliJ .idea Files! That's not good.

Please make cleaner.

Also Documentation need to be small. The best Docmentation is the code itself. Make it reliable and easy to understand. Good namings are good too.


Good Luck. Seems interesting this project.
But why Netty 4?


Also i think this project will not have future. But if you don't "give up", good luck.

- - - Updated - - -

Also please, Good Commit Names.

A commit name called "Updates n' shit. …" What the hell.

Documentation doesn't necessarily need to be small, especially not in Java (I don't know if you know). My current documentation I believe is simple and brief, just not "C# small".

If you're not following the project then why do you care about the commit? My GitHub is fine.

Why not Netty 4? It's the latest STABLE Netty release. I'd rather have a library that is confirmed to be stable, than the latest version of it.

Is really arrogant you say that "If you're not following the project then why do you care about the commit? My GitHub is fine."
If you know, if someone "Watching" you Repository that means these people are following.

Do not care? The Community cares.

C# Small? Why you saying documentation in C# is Small? If you're talking about XML Documentation from Visual Studio, you can implement it with many Arguments.

Also read that: The Golden Rules of Code Documentation | Java, SQL and jOOQ.

Tips:
1. If is a Class, you need Explain the Functionality of The Class, What the Class does.
2. If is a Getter Setter, you need Document what is setted, what allowed types or "regex" are allowed, etc.etc.

You don't need Explain which every variable is. Is massive. Only the types and main usage.

A good documentation are Variables that are explained as itself.
Java you don't need huge documentation. Since Java mainly follows as base Google's Java Code Style, Java is a Language that is totally followed by Software Design Patterns. You can't do "embarassing" and "bad" code layouts.

Java follow's in everything the MVCP and OO* Styles, since in Visual Artefacts and Code Artefacts. You can see how a Simple Windows is coded, with a View, Model, Controller, Listeners (for Actions), and etc.

Java documentation doesn't be huge, since Every Good Java IDE (Eclipse, IntelliJ) show Native Variables and Methods Documentation (passing the mouse).

You only need code good names and a good Class View Layout (i'm talking about Software Class Diagram).
Good Namespace and Classes Structure, good Classes Name, Good Methods Name, Good Variables Name.

Not num1, num2, string2, or someSring, or like WebWorker webWorker = new ... (we already know is a WebWorker!)

Also i'm only giving you a tip, you don't need go to personal side or leave as offense!

Other tip, please do a good Entitiy-Relationship Model for your Project. Since you're using the Entire Universe Packages in your project.

- - - Updated - - -

Say that your github is fine, when other say is not, it's the same as someone say your house is on fire! and you say no isn't everything is normal.

Accept critics. The reason of i say is weird is exactly why need to be good namings!

Commit name aren't to the OWNER understand or COLLABORATOR understand since he is doing the commit.
Is for OTHER PEOPLE THAT DOESN`T KNOW, Understand WHAT IS THIS COMMIT, WHAT CHANGES, THE REASON OF CHANGING.


Good Luck. I will no longer follow this development. Since this Guy is a badass.

Sadly, you are the only one who feels this way about my GitHub. And because you were rude about it, your suggestions are null and void, no pun intended :).

Any update's ?

Any Updates² or dead?

Well @ovflowd is right. You shouldnt have folders like .idea in your github

But good luck! :-)

I realize how I was being an asshole towards @ovflowd, I apologize for that. Decided to go easy on the documentation, and briefly re-writing the source before continuing to the client (not just because of the documentation).

Although, random question to settle my stress (O.C.D), I'd like your opinion on the folder structure-- should the Gaia.java be located in the /boot folder?

Anyways, I'll post more updates on that soon!

OFF-T:
Updated my JavaScript emulator for those who forked. :)

P.S.
Possibly switching to PostgreSQL or allowing multiple drivers.

You don't actually have OCD so it doesn't matter where Gaia.java goes...

Well because you can't self diagnose OCD, nor do you "have OCD when it comes to programming".

If you firmly believe you have OCD you should see a psychologist.

I didn't just "self diagnose" many people have told me this, while watching me code.

But I'll take your advice, thanks!

So, other NOT PSYCHIATRISTS think you have a serious mental health issue? Uh-huh.

You're not obsessive, you're indecisive. Where you put a class in your folder structure doesn't really matter. If you really had OCD you'd have like a million sub-folders.

Point proven? This has nothing to do with the project, however, I do still need opinions on whether to put in a boot folder.

Stop wasting time, you don't need opinions on what to put in folders.

Updated the source rewrite, might end up switching to Spring.

Looking good. It's refreshing to see someone else following the micro service architecture approach. Good luck :):

Sorry for the lack of updates, been working on a C++ project with a friend.
Source updated, check GitHub if you're still following the development.

Safe to say this development is dead, right?
