Module Database
Manage sets of units and groups.
#Database class
Mission designers can use the DATABASE class to build sets of units belonging to certain:
- Coalitions
- Categories
- Countries
- Unit types
- Starting with certain prefix strings.
This list will grow over time. Planned developments are to include filters and iterators. Additional filters will be added around Zone#ZONEs, Radiuses, Active players, ... More iterators will be implemented in the near future ...
Administers the Initial Sets of the Mission Templates as defined within the Mission Editor.
DATABASE construction methods:
Create a new DATABASE object with the DATABASE.New method:
- DATABASE.New: Creates a new DATABASE object.
DATABASE filter criteria:
You can set filter criteria to define the set of units within the database. Filter criteria are defined by:
- DATABASE.FilterCoalitions: Builds the DATABASE with the units belonging to the coalition(s).
- DATABASE.FilterCategories: Builds the DATABASE with the units belonging to the category(ies).
- DATABASE.FilterTypes: Builds the DATABASE with the units belonging to the unit type(s).
- DATABASE.FilterCountries: Builds the DATABASE with the units belonging to the country(ies).
- DATABASE.FilterUnitPrefixes: Builds the DATABASE with the units starting with the same prefix string(s).
Once the filter criteria have been set for the DATABASE, you can start filtering using:
- DATABASE.FilterStart: Starts the filtering of the units within the database.
Planned filter criteria within development are (so these are not yet available):
- DATABASE.FilterGroupPrefixes: Builds the DATABASE with the groups of the units starting with the same prefix string(s).
- DATABASE.FilterZones: Builds the DATABASE with the units within a Zone#ZONE.
DATABASE iterators:
Once the filters have been defined and the DATABASE has been built, you can iterate the database with the available iterator methods. The iterator methods will walk the DATABASE set, and call for each element within the set a function that you provide. The following iterator methods are currently available within the DATABASE:
- DATABASE.ForEachAliveUnit: Calls a function for each alive unit it finds within the DATABASE.
Planned iterators methods in development are (so these are not yet available):
- DATABASE.ForEachUnit: Calls a function for each unit contained within the DATABASE.
- DATABASE.ForEachGroup: Calls a function for each group contained within the DATABASE.
- DATABASE.ForEachUnitInZone: Calls a function for each unit within a certain zone contained within the DATABASE.
