Overview

MBot is a multi-purpose discord bot with administrative commands, mini-games, currency system, and experience system that was created for entertainment purposes.

Inspiration

As someone who uses Discord frequently, I wanted to create a bot that automated my tasks and could be used for entertainment purposes.

How it’s made

As this was just a bot within Discord, it was mostly backend work. After initially setting up the bot to accept commands using Discord.js (Node.js module) , I was ready to start implementing features. I developed the features through an iterative process, where I would first brainstorm what the feature required (database, libraries, etc.), then implementing and coding the feature, and then finally testing the feature thoroughly to make sure it worked properly and didn’t have any bugs.

The database schema consisted of 5 main fields: userID, serverID, money, xp, and level. A schema gets created for each user upon typing in the chat. The data can be read and updated depending on the command.

Schema

After about 3 months of adding features, I deemed it to be sufficient to publish online so that other people could use it. Initially, I used Heroku for hosting but they later announced that they would get rid of their free tier so I migrated to Railway.

Challenges

Figuring out the best way to implement features was the biggest challenge, especially the ones that required a database since I had no prior knowledge of using databases. With enough research, I learned how to update and retrieve user data from MongoDB. This knowledge helped me implement many important features, such as the experience and currency system, as well as user profiles.
