Member Enumeration Documentation

◆ CargoAcceptState

enum GSIndustry::CargoAcceptState

Ways for an industry to accept a cargo.

Enumerator
CAS_NOT_ACCEPTED	The CargoID is not accepted by this industry.
CAS_ACCEPTED	The industry currently accepts this CargoID.
CAS_TEMP_REFUSED	The industry temporarily refuses to accept this CargoID but may do so again in the future.

◆ IndustryControlFlags

enum GSIndustry::IndustryControlFlags

Control flags for industry.

Enumerator
INDCTL_NO_PRODUCTION_DECREASE	When industry production change is evaluated, rolls to decrease are ignored. This also prevents industry closure due to production dropping to the lowest level.
INDCTL_NO_PRODUCTION_INCREASE	When industry production change is evaluated, rolls to increase are ignored.
INDCTL_NO_CLOSURE	Industry can not close regardless of production level or time since last delivery. This does not prevent a closure already announced.
INDCTL_EXTERNAL_PROD_LEVEL	Indicates that the production level of the industry is controlled by a game script.
