Help Junior developer, looking to intern on a non-profit project.

[zambog420]

Hi everyone, let me introduce myself—I'm Martin, a junior developer.

I'm diving into the world of L2 servers, and honestly, I'm super overwhelmed about where to start learning the right way to set up, configure, and run a server.
There are so many datapacks—free, private—but it's so much that my head feels like it's going to explode.

I'm currently looking for someone or an active project willing to take me on as an intern. I'm not looking to make money—I'm just here to learn and grow out of pure passion for L2.

I've already been working with L2jMobius H5. I managed to edit the Community Board, add a buffer, GM Shop, and teleports.
I've also created custom NPCs for the GM Shop, and imported new custom weapons and armors—complete with original glow effects, like the Valakas and Antharas weapons.

But there's still a lot I don't know, and it can get overwhelming.

That’s why I’m looking for someone—or an active non-profit project—willing to take me on as an intern. I’m not looking to make money; I just want to learn, contribute, and grow out of pure passion for L2.

If you’re working on a project and could use a motivated learner who’s eager to help, I’d love to connect!

Did you forget to write junior developer in which direction? (java/ui/.....?)

[zambog420]

Hi, yes, I forgot to mention it, sorry. I'm currently familiar with Python, HTML, and Java. By UI, do you mean user interface?

why you use chatgpt?

In my opinion, if you're looking for completely open-sourced projects where you are able to contribute.

Interlude (aCis): Official Repo
High-Five (Mobius): Official Repo

Both are respectable projects, but Mobius is going to need a lot of tidying up though. If you're looking for guidance on client development, that's a little more complicated so you'd probably be better off learning that side of things once you have a better idea of specifically what you want to do.

Okay, I understand. Tnx

if i was you i would check first argentinian developer team to learn and contribute then start my own project privatly and then practice in free coding for my self, then you would be ready to learn standards and code out of nothing, and if you fail means you are in good path, if you win you are in for higher level, whatever you do be persistent and focused, thats what i did when i had time.

Si yo fuera tú, primero buscaría un equipo de desarrolladores argentinos para aprender y contribuir, luego comenzaría mi propio proyecto de forma privada y luego practicaría codificación libre por mi cuenta, entonces estarías listo para aprender estándares y codificar de la nada, y si fallas significa que estás en el buen camino, si ganas estás en un nivel superior, hagas lo que hagas, se persistente y concentrado, eso es lo que hice cuando tuve tiempo.

Okay, I understand. First, to get started by contributing to open projects and learning along the way. Then, when you mention starting my own project privately, do you mean taking a free datapack like L2jMobius and trying to make it functional for an online server? Great, thank you very much — all this information is really helpful. I’ve been reaching out to several server admins here in Argentina, but it seems like none of them have the time or interest to take on an intern or assistant. xd

 

P.S.: Are you the creator of Hopzone? Brings back memories of when I was a kid, downloading servers at the cyber café. For two dollars, I could spend the whole day playing and eating candy like crazy.

Another question: between L2jMobius, L2jServer, and aCis, which one has ALL of its code free?
As you probably noticed, I'm using ChatGPT to help me translate things, lol, and it suggested the following:

Project	Status	Open Source	Accepts Juniors?	Difficulty
L2JMobius	Very active	Semi-closed	Partially (with patches)	Medium-High
L2JServer	Active	Fully open	Yes (directly on GitHub)	Medium
aCis	Semi-active	Unofficial	Not very clear	Low

aCis	Semi-active	Unofficial	Not very clear	Low

 

L2JMobius->Medium-High. It's funny, all their code is quite simple, just like aCis.

[Mobius]

No drama, no finger-pointing, just undeniable results.

2000+ concurrent players. Zero lag.
The math is simple: simpler code = better code = better performance.

Meanwhile, other projects cry at 200-300 online.
Because bloat code and misinterpreting retail files isn't a feature.

Sin drama, sin acusaciones, sólo resultados innegables.

Más de 2000 jugadores simultáneos. Sin lag.
La matemática es simple: código más simple = mejor código = mejor rendimiento.

Mientras tanto, otros proyectos se quejan de tener 200-300 usuarios en línea.
Porque el código inflado y la mala interpretación de los archivos minoristas no son una opción.

Great! From what I can see, L2jmobius has very good reviews. Anyway, I've been testing it for months now and the file organization and modularity are impeccable. Everything is very easy to understand and locate. I'll need to learn with this datapack until I feel confident enough to buy the pro version.

Medium - High mobius ???   I would say is the most clean and easy to understand around.
From the other hand .. use what ever you like, good luck.

mobius has serious problems with the movement code and synchronization of npc and players.  aCis did it better
There are big problems with multithreading

Hay grandes problemas con el multihilo.

really ? xd my head is going to explode. I don't know what to do anymore

aCis is one of the oldest live pack after L2J (dec 2010) - it focuses solely on retailness and vanilla concept, over IL chronicle. It got a public and private gitlabs, because open source in L2J community is either toxic (resell/steal your work) or ungrateful. Still, a public rev is shared from time to time.

Regarding junior acceptance, you can contribute based on public revision, earn "cookies" and when you reach a given amount you can be directly registered into the private gitlab (such as Bandnentans lately). You can review all ppl who worked over aCis here : https://acis.i-live.eu/index.php?action=hof

I already had good experience with one argentinian, fernandopm, which worked under scripts rework back in 2011-2013. He came with 0 knowledge, but in the end could produce scripts.
