🛡️ Argentum Online Server

🛡️ How to Run My Server:

Create a new folder named C:\AO20 and navigate to it. Follow these steps:

Clone the repository git clone https://github.com/ao-org/argentum-online-server.git
Rename the file Example.Server.ini to Server.ini
Rename the file Example.feature_toggle.ini to feature_toggle.ini
Rename the file Empty_db.db to Database.db
Clone Recursos (https://github.com/ao-org/Recursos)
Open Visual Basic 6 as an administrator
Open the file Server.VBP

🔛 Feature Toggle/Flag (Turn ON/OFF features)

When introducing new functionality to the server, it should include the capability to be disabled. To achieve this, we implement the feature flags design pattern, which is configured within the file Example.feature_toggle.ini.

🎬 Game Scenarios

In the following folders, you will find configuration files for events. When programming a new type of event, it must have its own configuration file. https://github.com/ao-org/Recursos/tree/master/Dat/Scenarios

🗄️ SQL Migrations

To modify the schema of the database or make alterations to existing tables, it is essential to create a new SQL migration file within the ScriptsDB directory. The project is configured to automatically detect and execute the required migration scripts. This process ensures that the database is systematically updated to reflect the latest schema changes without manual intervention. This approach not only maintains database integrity but also streamlines the update process, enabling seamless transitions between different database schema versions.

🛡️ Pull Requests

We have a pre-commit hook for the project, Visual Basic 6 IDE changes the names of the variables and it makes the Pull Requests very difficult to understand.

Please run the following commands with git bash or the client you are using.

chmod +x .githooks/pre-commit
git config core.hooksPath .githooks

Basically the pre-commit hook runs when you make a git commit and it will run the file git_ignore_case.sh to avoid false changes in the Pull Request. Is not perfect but it helps a lot. Please send the Pull Requests with only the neccesary code to be reviewed.

In case you have problems setting locally your pre-commit hook you can run the file git_ignore_case.sh by just doing double click.

🗺️ Maps Limitation 512 with VB6 Debugger

There is a limitation when running and debugging the game within Visual Basic 6. Due to VB6's constraints, it cannot load more than 512 maps during debugging. As a result, maps such as Dungeon Dinosaurios (Map 577) will not function properly and it will throw overflow error

🛡️ Requirements

Database SQLite

Installing SQLite ODBC Driver for 32-bit Systems

To integrate SQLite with ODBC on a 32-bit system, please download the appropriate driver from the following link:

SQLite ODBC Driver - 32 bits

Optimizing Database Performance

To enhance the performance of your SQLite database, consider changing the journal mode to Write-Ahead Logging (WAL) by executing the following SQL command:

PRAGMA journal_mode=WAL;

Write-Ahead Logging can significantly improve the write performance and concurrency of your database. For more information on how WAL mode benefits your database operations, please visit the SQLite WAL documentation:

SQLite Write-Ahead Logging

This mode enables most read operations to proceed without locking and allows updates to occur without interfering with reads, thus increasing the performance and scalability of your application when using SQLite.
