Basic event bus for unity

BasicEventBus

Basic event bus for unity

• Structs for events - no garbage
• Interface based subscription
• High performance (1mil events risen per frame at 60 fps on my machine)

Create an event

Create new struct, assign IEvent interface

public struct TestEvent : IEvent
{
   public string a;
   public float b;

}

Raising an event

Slower method (has to do lookup to resolve subscribers)

EventBus.Raise(new TestEvent()
{
    b = 7,
    a = "Hello"
});
                

Fast method (directly invoke raise on the generic bus)

EventBus<TestEvent>.Raise(new TestEvent()
{
    b = 7,
    a = "Hello"
});
                

Subscribing

1. Implement desired interfaces on a class

public class EventBusTest : MonoBehaviour,
    IEventReceiver<TestEvent>,
    IEventReceiver<OnResourceDrop>
{

2. Feed instance of it to EventBus.Register()

    void Start()
    {
        EventBus.Register(this);
    }

    private void OnDestroy()
    {
        EventBus.UnRegister(this);
    }

It will automatically subscribe everything, reflection is used only once on application start, after that everything is cached and mapped.
