UnityIoC

UnityIoC it's plugin for Unity3D which brings IoC containering to your games. Here is example how to use it:

Register service:

public interface ISettingsManager
{
    string Name
    {
        get;
        set;
    }
}

//
// Register singletone of SettingsManager as ISettingsManager.
//
[Register(typeof(ISettingsManager), Reuse.Singletone)]
public class SettingsManager : ISettingsManager
{
    public SettingsManager()
    {
        this.Name = "Jek";
    }

    public string Name
    {
        get;
        set;
    }
}

Use registered service in MonoBehaviour by inhereting from InjectableMonoBehaviour.

public class MainInjectableMonoBehaviour : InjectableMonoBehaviour
{
    [Dependency]
    ISettingsManager settingsManager;

    private void Start()
    {
        Debug.Log("Name from resolved dependecy: " + this.settingsManager.Name);
    }
}

Use registered service by container Dependency without inhereting.

public class MainWithDependency : MonoBehaviour
{
    Dependency<ISettingsManager> settingsManager;

    private void Start()
    {
        Debug.Log("Name from resolved dependecy(class): " + this.settingsManager.Value.Name);
    }
}

If you require to setup container manually you can use IContainerSetuper interface, here is example:

public class SomeContainerSetuper : IContainerSetuper
{
    public readonly Dependency<ISettingsManager> Settings;

    public void Setup(IContainer container)
    {
        Debug.Log("Name from setuper: " + this.Settings.Value.Name);
        Debug.Log(string.Format("Registered {0} services", container.GetServiceRegistrations().Count()));
    }
}

According to benchmarks on my machine it cost ~100ms of startup time to find all classes marked with attributes.

When you are inhereting from InjectableMonoBehaviour and using Dependency attribute to mark dependency it will cost additional 354ns(1ms = 1000ns) to find dependencies for current instance and plus 354ns per dependency to resolve.

When you using container Dependency method for resolving it will cost 34ns per dependency. So, I would like to recomend you to use this method for defining your dependencies.

If you found some bug or have a question don't hesitate to create issues.
