Comment

Inspiration

Making a good thing better. Some of us played Minecraft as children, some of us wanted to play it for the first time. All of us wanted to add cool features to an already cool game.

Video Playlists (showcasing more features)

What it does

Feature overview

Land plots

  • /claim: claim land 9 blocks at a time
  • /selfheal: heal up to 50 percent of your health on your own claimed land
  • /unclaim: unclaim land you own (9 blocks at a time)

General roleplay

  • /me: describes your actions to nearby players
  • /it: describe an event/narrative not performed by a specific player, e.g. "The sky broke like an egg into full sunset, and the water caught fire."
  • /roll: generates a random number between 0 and 100, used to determine if an action succeeds
  • /ID: show your ID card to nearby players
  • /rob: start looting the ship

What we used

  • Minecraft Java Edition
  • Bukkit: a server modification API implemented by some Minecraft servers that retains compatibility with unmodified, official Minecraft clients
  • Spigot: an open-source Minecraft server that supports the Bukkit plugin API
  • An open-source map, Eickelburg - The City

Challenges we ran into

  • Setting up the server took a long time, and it takes a lot of RAM
  • Multi-threading in Java
  • Dependency management
  • Minecraft does not let you make custom block entity models
  • Testing the plugin when 2 members didn't have copies of Minecraft

Accomplishments that we're proud of

  • Designing a mod for a game some of us spent their entire childhood playing!
  • Learning how to set up and manage a game server
  • Adding awesome features to an open-source project
  • Navigating a complicated build system

What we learned

  • Game server management
  • Java
  • Implementing a project with an API
  • How to think about what a player might want to do, and implement a way to do it

What's next for Minecraft Medieval Roleplay Mod

  • Improving the market feature by adding a visible inventory
  • Expanding the abilities for each role
  • Adding more benefits to owning land
  • Implementing more economy features
