Svelto-IoC: hierarchical DI container usage example

// Root Container:

    void SetupContainer()
    {
        container = new Container();

        // input
        container.BindSelf<GameControls>();
        container.BindSelf<MouseController>();
        container.BindSelf<CameraRig>();

        // vehicle builder
        container.BindSelf<VehicleBuilder>();
    }

// Vehicle builder:

public class VehicleBuilder : MonoBehaviour
{
    [Inject] IContainer ParentContainer { get; set; }


    public Vehicle Create()
    {
        // the "scope" container used to construct just a vehicle
        var container = CreateScopeContainer(ParentContainer);

        return container.Build<Vehicle>();
    }

    IContainer CreateScopeContainer(IContainer parentContainer)
    {
        var container = new Container(parentContainer);

        container.BindSelf<Vehicle>();
        container.BindSelf<Motor>();
        container.BindSelf<VehicleConstraints>();
        container.BindSelf<VehiclePlayerControl>();

        return container;
    }
}


// Usage:

var vehicleBuilder = rootContainer.Build<VehicleBuilder>();
var vehicle = vehicleBuilder.Create();
