Spacetraders 4: Visualizing the starting system
In this entry, I build a simple visual map of my starting SpaceTraders system. Using real system coordinates from the API, I plot waypoints in 2D and extend the idea into 3D by introducing a synthetic Z dimension to separate overlapping locations. Along the way, I run into a few surprisingly tricky problems around data grouping, symmetry, and Matplotlib’s 3D quirks—and briefly break my “no AI while coding” rule to get unstuck. The result is a compact 2D+3D system overview that finally makes the universe feel tangible instead of abstract.
Spacetraders 3: Getting to know the game
SpaceTraders is more than a collection of API endpoints. It’s a persistent simulation of a space economy, with ships, contracts, markets, and delayed consequences built directly into its design. This post takes a step back from implementation details and looks at how the game world is structured, how its main systems interact, and why understanding these mechanics upfront makes automation and data-driven play much easier later on.
