@ue-too/ecs / index / EntityManager
Class: EntityManager
Defined in: index.ts:480
Manages entity lifecycle and signatures.
Remarks
The EntityManager handles:
- Creating new entities (recycling IDs from a pool)
- Destroying entities (returning IDs to the pool)
- Storing and updating component signatures for each entity
Entities are represented as simple numbers (IDs) and the manager maintains a signature (bit field) for each entity indicating which components it has.
