如何在 Discord.NET 上设置轮换播放状态

Question

我想制作一个每 10 秒左右改变一次的播放状态，我知道如何在 JS 中做到这一点，但在 C# 中却不知道。有没有办法做到这一点，如果有，你是怎么做到的？

我一直在考虑是否可以尝试 for 循环，但我不知道它会如何工作。

您可以通过多种方式完成此操作，首先我建议您研究一个简单的 Timer 类。 .NET Timer Doc

根据上面的文档，你可以制作一个简单的控制台应用

private static Timer timer;
private static List<string> status => new List<string>() { "Status1", "Status2", "Status3", "Status4" };
private static int currentStatus = 0;

static void Main(string[] args)
{
    CreateTimer();
    Console.ReadLine();
    timer.Stop();
    timer.Dispose();
}

private static void CreateTimer()
{
    timer = new Timer(10000);
    timer.Elapsed += OnTimedEvent;
    timer.AutoReset = true;
    timer.Enabled = true;
}

private static async void OnTimedEvent(Object source, ElapsedEventArgs e)
{
    DiscordSocketClient client = new DiscordSocketClient(new DiscordSocketConfig()
    {
         //Set config values, most likely API Key etc
    });

    await client.SetGameAsync("Game Name", status.ElementAtOrDefault(currentStatus), ActivityType.Playing);
    currentStatus = currentStatus < status.Count - 1 ? currentStatus +=1 : currentStatus = 0;
}

OnTimedEvent 函数显示了一个快速示例，您可以如何使用 discord.net 库来做某事。

您可以利用System.Threading.Timer 来实现此目的。

//add this namespace
using System.Threading; 

//create your Timer
private Timer _timer;

//create your list of statuses and an indexer to keep track
private readonly List<string> _statusList = new List<string>() { "first status", "second status", "another status", "last?" };
private int _statusIndex = 0;

您可以使用 ready 事件来开始。只需在 DiscordSocketClient 上订阅 Ready 事件

private Task Ready()
{
    _timer = new Timer(async _ =>
    {//any code in here will run periodically       
        await _client.SetGameAsync(_statusList.ElementAtOrDefault(_statusIndex), type: ActivityType.Playing); //set activity to current index position
        _statusIndex = _statusIndex + 1 == _statusList.Count ? 0 : _statusIndex + 1; //increment index position, restart if end of list
    },
    null,
    TimeSpan.FromSeconds(1), //time to wait before executing the timer for the first time (set first status)
    TimeSpan.FromSeconds(10)); //time to wait before executing the timer again (set new status - repeats indifinitely every 10 seconds)
    return Task.CompletedTask;
}
