Class EntityService

java.lang.Object
com.deco2800.game.entities.EntityService
public class EntityService extends Object
Provides a global access point for entities to register themselves. This allows for iterating over entities to perform updates each loop. All game entities should be registered here. Avoid adding additional state here! Global access is often the easy but incorrect answer to sharing data.
