Handle prefabs

Handling dependency injection for prefabs can be tricky. But Ducktion has you covered. Simply attach the DynamicDependencyResolver component to your prefab and it will automatically resolve all dependencies for you when the prefab is instantiated.

It will resolve all dependencies for any component attached to the prefab using the Resolve attribute.

public class MyComponent : MonoBehaviour
{
    [Resolve] private IMyService _myService;
}

public class MyComponent : MonoBehaviour
{
    [Resolve] private IMyService _myService;
}

Internal

The component itself is very simple. It uses the Ducktion.singleton.ResolveDependencies method to resolve all dependencies:

using TheRealIronDuck.Ducktion.Attributes;
using UnityEngine;

namespace TheRealIronDuck.Ducktion.Components
{
    public class DynamicDependencyResolver : MonoBehaviour
    {
        private void Awake()
        {
            Ducktion.singleton.ResolveDependencies(gameObject);
        }
    }
}

using TheRealIronDuck.Ducktion.Attributes;
using UnityEngine;

namespace TheRealIronDuck.Ducktion.Components
{
    public class DynamicDependencyResolver : MonoBehaviour
    {
        private void Awake()
        {
            Ducktion.singleton.ResolveDependencies(gameObject);
        }
    }
}

TIP

If you can't use the DynamicDependencyResolver component for some reason, you can also use the Ducktion.singleton.ResolveDependencies method directly. The method can be applied to any GameObject or MonoBehaviour, and it will search for components marked with the Resolve attribute.
