Aura is an open-source server emulator written in C#. It's solely being developed for educational purposes, learning about programming, MMORPGs, maintaining huge projects, working with other people, and improving knowledge. It's not about playing a game or competing with any services provided by Nexon or its partners, and we don't endorse such actions.

Aura is completely free and licensed under the GNU GPL. As such, every user is free to use Aura and choose how to use it.

Compatibility to all major versions but NA was dropped on 2013-09-13 (Aura Legacy). Since that time, Aura is kept compatible only to the latest update of NA.

To run Aura, you need

• .NET 4.5 (Mono 3.0+)
• MySQL 5 compatible database

To compile Aura, you need

• C# 5 compiler, such as:
  • Visual Studio (2012 or later)
  • Monodevelop (With mono version 3 or greater)
  • SharpDevelop (Version 4.4 or greater)

• Compile Aura
• Run sql/main.sql to setup the database
• Copy system/conf/database.conf to user/conf/, adjust the necessary values and remove the rest.

Afterwards, you should be able to start Aura via the provided scripts or directly from the bin directories. If not, or if you need a more detailed guide, head over to our forums, Gitter chat, or wiki.

There are 4 ways you can help us to improve Aura:

1. Research
2. Bug reports
3. Pull Requests
4. Releases on the forums

Do research on NPCs, quests, skills, anything really that isn't implemented yet and post it on our research forum. The information you post will help developers to implement the features.

Report bugs on GitHub so they can be fixed ASAP. If you're not sure if you've found a bug or not, report it on the forum, and we'll clarify for you.

The fastest way to get code contributions into the source is a pull request, which, if well written, can be merged right in to master. To expediate this process, all pull requests must comply with our coding conventions below.

Alternatively you can make "casual" releases on the forum, which developers might pick up as research or as a base to implement the features into the official source.

• Base: MS Naming Guidelines, MS C# Coding Conventions
• Exceptions:
  • Use _private for private fields and this.Foobar for properties, public fields, and methods.
  • Use tabs, not spaces.
• Comment lines shouldn't exceed ~80 characters, other lines' lengths are irrevelant.
• Excessive usage of the auto-formatting feature is encouraged. (Default VS settings)
• Avoid regions.

Usually all errors are solveable by recompiling, running SQL updates from sql/, and deleting the cache folder.

This message means that the client wasn't able to connect to the channel, which is usually caused by configuration mistakes. Make sure you can reach the IP/Port you've set the channel to run on (channel.conf) from the affected computer.

In some rare cases this can also be caused by routers, for example, if you try to make the server publicly available and the router doesn't allow you to connect to your own public IP.
