Workers & Resources Under the Hood: Individual-Agent Economy & Network Logistics

Engine & Tech Stack

• Engine / language: a custom in-house engine from 3Division (not a mainstream off-the-shelf engine), tuned for large-scale economic and logistics simulation.
• Map representation: a heightmap-based 3D terrain with grid-aligned construction and road, rail, conveyor, pipeline and power networks laid over it.

Core AI & Decision Making

• Citizens: individuals are simulated with needs (work, food, goods, healthcare, education) and daily routines, and must physically travel to jobs and services.
• Dispatch: labour and demand are satisfied through the transport and distribution network rather than teleported resources.

State Management & Data Architecture

• Model: a resource-flow economy where every good is produced, stored, loaded, transported and consumed as a tracked quantity, with no money-only shortcuts.
• Networks: roads, railways, conveyors, pipelines and power lines are graphs that vehicles and resources route across.

Tick Scheduling & Performance Tricks

• Continuous sim: large populations and vehicle fleets are simulated continuously, with adjustable game speed to manage the load.
• Scale: the per-citizen and per-vehicle detail is exactly what makes performance scale with city size.

Pathfinding & Spatial Systems

• Vehicles: trucks and trains path over the road and rail graphs with one-way roads, junctions and signals; pedestrians route to nearby stops and services.
• Spatial: structure follows the transport network rather than open-terrain distance.
