GameEvent class abstract

Base class for all events dispatched through the EventBus.

Events are lightweight data objects that systems can fire and other systems can subscribe to, enabling decoupled communication.

class DamageEvent extends GameEvent {
  final Entity target;
  final double amount;
  DamageEvent(this.target, this.amount);
}

// Producer system:
world.events.fire(DamageEvent(entity, 25.0));

// Consumer system (in onAddedToWorld or initialize):
world.events.on<DamageEvent>((event) {
  // handle damage
});
