Dynamic Demand
Dynamic Demand is a mod for Subway Builder that enables changing demand data on some schedule. To accomplish this, it uses a calendar system, where the game is assumed to begin on Monday, January 1. Currently, all years are 365 days with no consideration of leap days, but this may change in the future if people want that level of detail.
At present, the modding API is not correctly fetching demand data files, so this mod is a glorified calendar system right now. But, it will be fixed soon, at which point this will become a real mod that actually does something more than add a date.
You will be able to use this mod to
- differentiate weekday vs. weekend demand
- change demand seasonally
- include day-to-day variability
- add demand for specific days of the year
Keep in mind that, for larger maps, demand files can be a dozen or more MB in size, so using many different demand data files can add up to be hundreds of MBs.
