This is the game server, the core system used to run the Massively Multiplayer online crafting adventure game Deepworld. We would typically run 1-2 servers per core and expect roughly 1gb maximum memory usage per server.
The codebase is primarily written in Ruby and heavily leverages EventMachine an evented concurrency framework with a fair amount of the serious bit twiddling written directly in C.
The server heavily relies on the Deepworld Master Config for game logic, so be sure to dig into that as well.
We plan to provide a better treasure map over the coming days/weeks, but in the codebase you'll find many things including:
- An application protocol, leveraging MessagePack server/messages/base_message.rb and server/commands/command_directory.rb
- An behavior tree AI system vendor/rubyhave gem and models/npcs/behavior
- A em-mongo based mongodb query library proving a simple mongo API lib/mongo_model
- A steam power system to connecting steam vents to "power" machines ext/lib/steam.c
- A simple liquid dynamics system ext/lib/liquid.c
- A "plant growth" system to progress plants based on exposure to light and water ext/lib/light.c and ext/lib/growth.c
- A binary world data format stored in chunks / blocks including a migration system inspired by ActiveRecord models/zone.rb and ext/lib/zone.c
- An extremely comprehensive RSpec test suite spec folder
- A simulator to connect and control sim players for testing script/simulator
- Many many more things that we're forgetting but hopefully will enumerate in the coming days
