The OnVBloodDeath event in ScarletCore allows you to listen for, inspect, and react specifically to V Blood unit death events in the game. This is useful for custom boss logic, analytics, boss-based triggers, or implementing special effects and mechanics for V Blood deaths in your mod.

public static event EventHandler<DeathEventArgs> OnVBloodDeath;

• sender: The DeathEventListenerSystem instance that detected and raised the event.
• args: A DeathEventArgs object containing all relevant information about the batch of V Blood deaths.

• List<DeathInfo> Deaths — List of all V Blood deaths that occurred in the frame
• int DeathCount — Number of V Blood deaths in this batch

• Entity Died — The V Blood entity that died
• Entity Killer — The entity that caused the death
• Entity Source — The source of the damage/death

EventManager.OnVBloodDeath += (sender, args) => {
    foreach (var death in args.Deaths) {
        Log.Info($"[VBloodDeath] {death.Died} was killed by {death.Killer} (source: {death.Source})");
    }
};

EventManager.OnVBloodDeath += (sender, args) => {
    Log.Info($"V Blood deaths this frame: {args.DeathCount}");
};

You can use a named method for your handler. The method must match the event signature:

void OnVBloodDeathHandler(object sender, DeathEventArgs args) {
    // sender is the DeathEventListenerSystem instance
    foreach (var death in args.Deaths) {
        // Custom logic here
    }
}

EventManager.OnVBloodDeath += OnVBloodDeathHandler;
EventManager.OnVBloodDeath -= OnVBloodDeathHandler; // Unsubscribe when done

Note: When using a method handler, the first parameter must be of type object (the sender, which is the DeathEventListenerSystem instance), and the second parameter must be of type DeathEventArgs.

The sender parameter is the DeathEventListenerSystem instance that detected the V Blood death. You can cast it if you need to access system-specific methods or properties:

EventManager.OnVBloodDeath += (sender, args) => {
    var deathSystem = sender as DeathEventListenerSystem;
    // Use deathSystem if needed
};

You can register multiple handlers. All will be called in order.

Always unsubscribe your handler when it is no longer needed to avoid memory leaks:

EventManager.OnVBloodDeath -= OnVBloodDeathHandler;

• Custom V Blood/boss death logic or effects
• Analytics and logging for boss deaths
• Boss death-based triggers or achievements
• Special effects for boss encounters

Tip: For more advanced death features, combine this event with other ScarletCore systems and services.
