Show HN: A self-running space economy SIM in Rust and Bevy
TL;DR
A self-running space economy simulator has been developed using Rust and Bevy, featuring hundreds of autonomous ships that trade and manage resources in a dynamic solar economy. This simulation allows users to observe a complex economic system without a predefined storyline or player objectives.
✦ Why It Matters
Explore agent-based modeling in your projects to simulate complex systems effectively.
Key Takeaways
- Experiment with the simulation by running it locally using Rust.
- Contribute to the project by forking the repository and submitting pull requests.
- Utilize the SQLite persistence feature for data management in your own projects.
- Explore the architecture documentation for insights into building scalable simulations.
How It Works
The simulation operates with autonomous ships that utilize a GOAP planner to determine their actions based on real-time economic conditions. Each ship evaluates potential goals, such as trading or refueling, and dynamically adjusts its plans mid-flight to optimize for the best outcomes.
The economy is driven by a coverage model that prices commodities based on supply and demand, allowing for a realistic simulation of market behaviors.
