unity3d - 从 SettingCollection 中选择 GameObject

Question

我正在使用 Zenject 框架，我想为工厂创建的类实例化 gameObject。为此，我在 GameInstaller 中使用了类似的东西

Container.BindFactory<int,int,Hex, Hex.Factory().
    FromComponentInNewPrefab(_settings.PlainHexPrefab[0]).
    WithGameObjectName("Hex").
    UnderTransformGroup("Zenject");`

它工作正常，但在我的 _settings.PlainHexPrefab 中，我收集了 GameObjects，我需要通过 Hex 对象的属性选择其中一个依赖项。我怎么能做到？

以下三种方法可能对您有用：

1. 从方法

   public class Hex : MonoBehaviour
   {
       public class Factory : PlaceholderFactory<int, int, Hex>
       {
       }
   }
   
   public class TestInstaller : MonoInstaller<TestInstaller>
   {
       public GameObject[] HexPrefabs;
   
       public override void InstallBindings()
       {
           Container.BindFactory<int, int, Hex, Hex.Factory>().FromMethod(CreateHex);
       }
   
       Hex CreateHex(DiContainer _, int p1, int p2)
       {
           var prefab = HexPrefabs[Random.RandomRange(0, HexPrefabs.Count() -1)];
           return Container.InstantiatePrefabForComponent<Hex>(prefab);
       }
   }
   

2. 定制工厂

   public class HexFactory : IFactory<int, int, Hex>
   {
       readonly DiContainer _container;
       readonly GameObject[] _prefabs;
   
       public HexFactory(
           GameObject[] prefabs,
           DiContainer container)
       {
           _container = container;
           _prefabs = prefabs;
       }
   
       public Hex Create(int p1, int p2)
       {
           var prefab = _prefabs[Random.RandomRange(0, _prefabs.Count() -1)];
           return _container.InstantiatePrefabForComponent<Hex>(prefab);
       }
   }
   
   public class TestInstaller : MonoInstaller<TestInstaller>
   {
       public GameObject[] HexPrefabs;
   
       public override void InstallBindings()
       {
           Container.BindFactory<int, int, Hex, Hex.Factory>()
               .FromIFactory(b => b.To<HexFactory>().AsSingle().WithArguments(HexPrefabs));
       }
   }
   

3. 定制工厂中的子工厂。这还有一个好处是每个预制工厂都应该被“验证”

   public class CustomHexFactory : IFactory<int, Hex>
   {
       readonly List<Hex.Factory> _subFactories;
   
       public CustomHexFactory(List<Hex.Factory> subFactories)
       {
           _subFactories = subFactories;
       }
   
       public Hex Create(int p1)
       {
           return _subFactories[Random.RandomRange(0, _subFactories.Count() -1)].Create(p1);
       }
   }
   
   public class TestInstaller : MonoInstaller<TestInstaller>
   {
       public GameObject[] HexPrefabs;
   
       public override void InstallBindings()
       {
           foreach (var prefab in HexPrefabs)
           {
               Container.BindFactory<int, Hex, Hex.Factory>().FromComponentInNewPrefab(prefab)
                   .WhenInjectedInto<CustomHexFactory>();
           }
   
           Container.BindFactory<int, Hex, Hex.Factory>().FromFactory<CustomHexFactory>();
       }
   }
