问题[c#]

有一个界面：

public interface IUpdatable 
{
    public void Awake();
    public void Start();
    public void Update();
    public void FixedUpdate();
    public void LateUpdate();
}

该接口旨在从不继承自的类中提取 Unity 方法MonoBehaviour。我有一个PlayerController实现该接口的类。

这是装饰器本身。我试图使用接口将所有调用集中在一个地方，但是当我运行它时，它至少List<IUpdatable> updatable有一个后继者。Count = 0;IUpdatable

public class UpdatableDecorator : MonoBehaviour
{
    private List<IUpdatable> _updatables  = new();
    
    [Inject]
    public void Construct(List<IUpdatable> updatable)
    {
        _updatables.AddRange(updatable);
        Debug.Log(_updatables.Count);
    }
    private void Awake()
    {

        foreach (var awake in _updatables)
        {
            awake.Awake();
        }
    }
    void Start()
    {
        foreach (var start in _updatables)
        {
            start.Start();
        }
    }


    void Update()
    {
        foreach (var update in _updatables)
        {
            update.Update();
        }
    }
    private void FixedUpdate()
    {
        foreach (var fixedUpdate in _updatables)
        {
            fixedUpdate.FixedUpdate();
        }

    }

    private void LateUpdate()
    {
        foreach (var lateUpdate in _updatables)
        {
            lateUpdate.LateUpdate();
        }
    }
}

绑定如下所示SceneInstaller：

private void BindDicorator()

{
      Container.Bind<List<IUpdatable>>().AsSingle();
      Container.BindInterfacesAndSelfTo<UpdatableDecorator>().FromComponentInHierarchy().AsSingle();
}

我不知道我做错了什么。我将非常感激您的指导。

大家好。有一个代码可以找到物体之间的最小距离并选择该物体以便在游戏中进行进一步的交互。

我看到并知道代码看起来很糟糕，但我不知道如何正确缩短它（例如，使用 foreach）。

请帮助我，但不要冒犯我）

代码：

void Distanse()

            if (tmp1 < distance)
            {
                distance = tmp1;
                botNearest = bots[0];
            }
        }

        if (players[1] != null)
        {
            float tmp1 = Vector3.Distance(players[1].transform.position, bots[0].transform.position);

我的目标是在 ListBox 中显示最新添加的项目。严格来说，我是通过ListBox输出控制台来模拟的。 AvaloniaListBox没有方法ScrollToEnd，但是它有一个方法ScrollIntoView，但不幸的是没有效果。我在 GitHub 上找到了一个关于此问题的问题，其中讨论了通过在 UI 线程中运行方法来解决此问题，但这也没有任何效果。我的搜索让我找到了ScrollViewer具有所需方法的东西ScrollToEnd，但是在加载表单时我无法加载它。可能是因为当内容不适合视口时它就被隐式地创建了。通过这个我可以弄清楚，但我有一个问题：我做的一切都正确吗，或者有没有更简单的方法？

我正在 Docker 容器中的 ASP.NET 上创建分布式分散数据存储系统。使用 Chord (DHT)。在节点之间保存文件可以正常工作 - 它们被分发和存储。尝试从节点上传（下载）文件时出现此问题。我无法从日志中找出问题所在。错误可能出在哪里？
