Question

我读了很多文章，但我似乎没有得到它。我现在有这个代码工作，因为我硬编码3秒延迟，所以有足够的时间进行网络通话，所以当显示分数时有数据。但我真正想要的是让网络通话结束，然后显示分数。救命？

 IEnumerator Start()
{
    client = new MobileServiceClient(_appUrl, _appKey);
    table = client.GetTable<Highscore>("Highscores");
    yield return StartCoroutine(ReadItems());
    DisplayScores();
}

void Update()
{

}

public void btn_GoBack()
{
    Application.LoadLevel("StartScene");
}

private void OnReadItemsCompleted(IRestResponse<List<Highscore>> response)
{
    if (response.StatusCode == HttpStatusCode.OK)
    {
        Debug.Log("OnReadItemsCompleted data: " + response.Content);
        List<Highscore> items = response.Data;
        Debug.Log("Read items count: " + items.Count);
        Scores = items;
    }
    else
    {
        Debug.Log("Error Status:" + response.StatusCode + " Uri: " + response.ResponseUri);
    }
}

private IEnumerator ReadItems()
{
    table.Read<Highscore>(OnReadItemsCompleted);
    yield return new WaitForSeconds(3);
}

private void DisplayScores()
{
    txtHighScores.text = "";
    int numberOfScores = Math.Min(Scores.Count, 5);

    for (int i = 0; i < numberOfScores; i++)
    {
        string name = Scores[i].username.ToString();
        string score = Scores[i].score.ToString();

        txtHighScores.text += (i + 1).ToString() + ". " +
                              " - " + name + "\r\n" +
                              score.ToString().PadLeft(4, '0');
    }
}

Answer 1

使用Startcorutine方法传递参数很重要，否则会出错。所以在你的代码中尝试我的修复。

 IEnumerator Start()
{
    client = new MobileServiceClient(_appUrl, _appKey);
    table = client.GetTable<Highscore>("Highscores");
    yield return StartCoroutine(ReadItems(2.0f)); //delay
    DisplayScores();
}

IEnumerator ReadItems(float delay)
{
    yield return new WaitForSeconds(delay);
    table.Read<Highscore>(OnReadItemsCompleted);

}

删除＆＃34; DisplayScores()＆＃34;的方法调用来自Start()
并插入DisplayScores()作为方法回调的最后一行OnReadItemsCompleted
然后您应该删除行yield return new WaitForSeconds(3);

在继续Unity3d中的代码之前等待Web调用完成
