AutoWire Notes and Thoughts

Main

// --- AutoWire ---
// Service Locator pattern is inferior to DI, but that is what we are stuck with in Unity, so lets make our life easier
//
// Notes:
// 1) any persistent state should be a component or belong to a component (no models, services in thin air)
// 

public class Enemy : AutoWire
{	
	[Locate] 
	public Transform { get; set; } // Will find the component on this gameobject
	
	[Locate] 
	public EnemiesManager { get; set; }	// wont find the component so will look into AutoWire cache and pull out an instance, 
										// failing that it will do this.FindComponentInParent, 
										// failing that it will use GameObject.FindObjectOfType	
										
	[Locate]
	public INotificaitonService { get; get; } // will look into the AutoWire cache for a mapping of this interface
	
	// Illegal because AutoWire declares Awake as private
	void Awake()
	{
	}

	// If we need to so something in awake use this instead
	override protected void OnAwake() 
	{	
	}
}

// This is a class purely for convenience, you could just do AutoWire.WireUp(this); in your own monobehaviour awake 
// and thus not need to extend this class at all
public class AutoWire : MonoBehaviour
{
	private void Awake()
	{
		AutoWire.WireUp(this);
		OnAwake();
	}
	
	virtual protected void OnAwake() {}
}

// When AutoWire locates this class for something else it will automatically be put into the cache
[AutowireCache]
public class EnemiesManager : MonoBehaviour
{
}

// Here we bootstrap the game and use Edit > Project Settings > Script Execution Order to ensure that its always loaded first
public class Bootstrap 
{
	public GameObject managers;

	void Awake()
	{
		// Whenever the locator is asked for INotificaitonService it will look for AndroidNotificationService instead
		AutoWire.Map<INotificaitonService>().To<AndroidNotificationService>();	
		
		// Will get all the components from the managers object and cache them immediately 
		// so AutoWire doesnt have to go looking for them once they are first requested
		AutoWire.CacheAllComponentsIn(managers);
	}
