Global Events
Warudo contains a EventBus class that allows you to subscribe to and broadcast global events. To define a custom event class, inherit from the Warudo.Core.Events.Event class. For example:
public class MyEvent : Event {
public string Message { get; }
public MyEvent(string message) {
Message = message;
}
}
To subscribe (listen) to an event:
Context.EventBus.Subscribe<MyEvent>(e => {
Debug.Log(e.Message);
});
To broadcast (fire) an event:
Context.EventBus.Broadcast(new MyEvent("Hello, world!"));
You should unsubscribe from events when you no longer need to listen to them:
var subscriptionId = Context.EventBus.Subscribe<MyEvent>(e => {
Debug.Log(e.Message);
});
// Later
Context.EventBus.Unsubscribe<MyEvent>(subscriptionId);
Subscribing Events In Entities
If you are writing code inside an entity type, you can use the Subscribe method directly to avoid handling event subscription IDs:
// Inside an entity type, i.e., asset, node, plugin, structured data
Subscribe<MyEvent>(e => {
Debug.Log(e.Message);
});
The events are automatically unsubscribed when the entity is destroyed.
