- Entity
- a collection of components that represents a thing in the game
- Component
- a piece of data
- System
- logic that operates on a certain set of entities
- Capability
- collection of components
- systems require capabilities from entities
- entities inherently have capabilities, because they consist of components
Operations that should be possible
- iterate over all entities
- iterate over all entities that have a certain capability
- remove an entity and associated entry from the lists in entityMap
- remove from entityList
- find out which capabilities in capabilityMap match the components of the entity and delete the entity from those lists
- add entity
- add components
- iterate all capabilities in capabilityMap and add it to the ones that have matching components
- add component to entity
- check that component does not exist already
- just add component
- check capabilityMap for new matching capabilities and add the entity to those lists
- remove component from entity
- similar to removing an entity
