| // The setup: I have an Entity class hierarchy for server/common/client, and each entity has | |
| // a reference to an entity_manager, which should be templated to the appropriate type so | |
| // that an entity getting other entities from the manager always get the correct type of | |
| // entity back. | |
| // The common code: | |
| interface EntityManager<Entity extends EntityCommon = EntityCommon> { | |
| entities: Partial<Record<number, Entity>>; | |
