Question

我有SceneA（A）和SceneB（B）。 B也有一个由SceneContext安装程序安装的Foo AsSingle和NonLazy。 Foo对Debog.Log（“ Hello Errors！”）实现了IInitialize：

yield return LoadScene("SceneA");
yield return new WaitForSeconds(2.0f);
SceneManager.LoadScene("SceneB");
yield return new WaitForSeconds(2.0f);
var newSceneContainer = ProjectContext.Instance.Container.Resolve<SceneContextRegistry>()
.SceneContexts.Single().Container;
Foo foo = newSceneContainer.Resolve<Foo>();

我猜到“无法解析该类”，而在调试中我看到了Foo的问候消息，因此安装程序已完成其工作。现在，如果Foo是MonoBehaviour，则在Zeneject将游戏对象绑定为“来自场景”的组件的游戏对象上，那么毫无问题，它将得到解决。在这种情况下，请让我知道如何解决。

Foo重命名为“ BClass”。 A的安装程序为空。 B的代码：

public class BInstaller : MonoInstaller
{
    public override void InstallBindings()
    {
        Container.BindInterfacesAndSelfTo<BClass>().AsSingle().NonLazy();
    }
}

public class BClass : IInitializable, IDisposable {
    public void Initialize() { Debug.Log("Hello Errors!"); }
    public void Dispose() { }
}

最后的测试：

public class ScenesFlow_A_to_B : SceneTestFixture
{
    [UnityTest]
    public IEnumerator TestScene()
    {
        yield return LoadScene("SceneA");
        //waiting
        SceneManager.LoadScene("SceneB");
        //waiting
        var newSceneContainer = ProjectContext.Instance.Container
        .Resolve<SceneContextRegistry>().SceneContexts.Single().Container;
        BClass bc = newSceneContainer.Resolve<BClass>() as BClass;
        Assert.IsNotNull(bc);// fail!
    }
}

新变化：

public class ScenesFlow_A_to_B : SceneTestFixture
{
    [UnityTest]
    public IEnumerator TestScene()
    {
        yield return LoadScene("SceneA");
        //SceneManager.LoadScene("SceneB");
        yield return SceneManager.LoadSceneAsync("SceneB");
        var newSceneContainer = ProjectContext.Instance.Container
        .Resolve<SceneContextRegistry>().SceneContexts.Single().Container;
        BClass bc = newSceneContainer.Resolve<BClass>() as BClass;
        Assert.IsNotNull(bc);
    }
}

结果将是这样：

Zenject Unity3D测试场景打“无法解决类”如何摆脱？
