Citybound
Citybound is an open-source multiplayer city simulation game and collaborative urban planner. It provides a shared digital space where multiple users co-manage city growth, design infrastructure layouts, and develop urban environments in real time.
The project functions as a collaborative city builder, allowing players to plan and evolve a virtual city together. Changes made to the urban environment are reflected immediately for all connected participants within the shared simulation.
The system utilizes an entity-component simulation to manage urban behavior and a shared-world coordinate system. Real-time synchronization is handled via websockets, employing authoritative state synchronization, delta-based updates, and client-side interpolation to maintain consistency across all users.
Features
- Real-time Collaboration - Provides a real-time shared environment for multiple users to collaboratively plan and build a city.
- Real-Time Building - Allows for the construction and evolution of a city with immediate reflections for all connected players.
- Collaborative Urban Planning - Enables multiple users to work together to design city layouts and infrastructure in a shared space.
- Entity Component Systems - Utilizes an entity-component system to manage city objects and decouple urban behavior logic.
- Urban Planning Tools - Functions as a shared digital space for co-managing city growth and infrastructure layout.
- Collaborative Simulation Environments - Offers a collaborative simulation environment where users collectively manage and evolve urban growth.
- Real-Time Communication - Uses WebSockets for persistent, bidirectional, low-latency communication of player actions and events.
- State Synchronization - Implements a mechanism to maintain consistent city state between the authoritative server and connected clients.
- Game State Interpolation - Smooths out visual movements of city entities by interpolating positions between server updates.
- Coordinate Systems - Employs a unified global grid coordinate system to ensure spatial consistency across all players.
- Open Source Games - Provides an open-source implementation of a city-building simulation game.
- Network State Delta Updates - Reduces network bandwidth by transmitting only specific changes in the simulation state.
- Business and Simulation - City builder simulating microscopic interactions of millions of individuals.
- Games & Entertainment - City simulation game.
