class: EntityGroup

[20:7] extends: EntityWorldListener

Wraps FXGL's EntityGroup (com.almasb.fxgl.entity.EntityGroup), an auto-updating filtered view of entities by one or more entity-type enums. The group listens for world add/remove events and keeps its own list of active matching entities for efficient frame-by- frame iteration. Build one with the GameWorld instance, initial entity list, and the list of type enums to track.
