RootLifetimeScope

Concepts

• The top-level LifetimeScope for a project.

• It lasts from the start of the game to the end.

• The ScreenSystem is also responsible for launching a kind of EntryPoint.

Implementation policy

• Page containers and modal containers are referenced via SerializeField.

• Register the two referenced containers.

  • IContainerBuilder type as an extension method of the ScreenSystem-supported RegisterPageSystemand RegisterModalSystem methods supported by ScreenSystem.

• Push the first page.

  • Create an EntryPoint class.

    • Implement it using the IStartable interface.

    • Register as a RegisterEntryPoint in the RootLifetimeScope.

    • Inject a PageEventPublisher and send a PageBuilder as a message to push the page.

  • Register other message brokers, network-related dependencies, etc.

public class RootLifetimeScope : LifetimeScope
{
    [SerializeField] UnityScreenNavigator.Runtime.Core.Page.PageContainer _container;
    [SerializeField] UnityScreenNavigator.Runtime.Core.Modal.ModalContainer _modalContainer;

    protected override void Configure(IContainerBuilder builder)
    {
        builder.RegisterPageSystem(_container);
        builder.RegisterModalSystem(_modalContainer);
        builder.Register<IHttpClient>(_ => new HttpClient(), Lifetime.Singleton);

        var options = builder.RegisterMessagePipe();
        builder.RegisterMessageBroker<MessagePipeTestMessage>(options);
        builder.RegisterEntryPoint<TestEntryPoint>();
    }

    private class TestEntryPoint : IStartable
    {
        private readonly PageEventPublisher _publisher;

        public TestEntryPoint(PageEventPublisher publisher)
        {
            _publisher = publisher;
        }

        public void Start()
        {
            _publisher.SendPushEvent(new TestPageBuilder());
        }
