SimCity 4 mod update resolves decades-old 'eternal commuter' pathfinding glitch
Network Addon Mod update 50 fixes regional routing loops and slashes the project's codebase using a dynamic-link library.
The short version
- The Network Addon Mod development team released update 50 for the 2003 title SimCity 4.
- The patch resolves the 'Eternal Commuter Loop' bug, a 23-year-old regional pathfinding issue that distorted traffic, demand, and city economies.
- The update introduces a mandatory DLL implementation that cuts over ten million lines of code from the mod.
Key facts
- Network Addon Mod (NAM) update 50 resolves the 'Eternal Commuter Loop' bug that has persisted since SimCity 4 launched in 2003.[Slashdot]
- The glitch caused simulated commuters to endlessly travel between city borders without taking jobs, disrupting regional zoning demand, traffic levels, and local economies.[Slashdot]
- The fix operates by blocking designated neighbor-to-neighbor pathways while permitting standard commuter traffic across other connections.[Slashdot]
- Integrating a mandatory DLL reduced the size of the NAM codebase by nearly 90 percent and more than ten million lines of code.[Slashdot]
- Update 50 also adds features such as diagonal street placement, street tunnels, improved slope tolerances, and tighter placement rules for adjacent infrastructure.[Slashdot]
