我正在创建一个状态，显示我的机器人有多少公会，但它不会更新

Question

我正在尝试为我的 Discord 机器人创建一个状态，它显示我的机器人所在的服务器数量。我希望它在每次将我的机器人添加到新服务器时刷新状态。这是我当前的代码：bot.on('ready', () => {  console.log(`${bot.user.username} is now ready!`);  status_list = ["stuff", `${bot.guilds.cache.size} servers`]  setInterval(() => {    var index = Math.floor(Math.random() * (status_list.length - 1) + 1);    bot.user.setActivity(status_list[index], { type: "LISTENING" });  }, 15000)});任何帮助将不胜感激，谢谢！

与其依赖间隔，不如使用guildCreate和guildDelete事件。每当机器人加入公会或从公会中移除时，它们就会分别被触发。看看下面的示例代码。

client.on("ready", () => {

    client.user.setActivity("Serving " + client.guilds.cache.size + " servers");

});

client.on("guildCreate", () => {

    // Fired every time the bot is added to a new server

    client.user.setActivity("Serving "+ client.guilds.cache.size +" servers");

});

client.on("guildDelete", () => {

    // Fired every time the bot is removed from a server

    client.user.setActivity("Serving "+ client.guilds.cache.size +" servers");

});

现在，如果您想将其与选择随机状态配对，您也可以执行以下操作：

const statusMessages = ['First status messages', 'Serving {guildSize} servers', 'Third possible message'];

let chosenMessageIndex = 0;

client.on("ready", () => {

    setInterval(() => {

        setRandomStatus();

    }, 15000);

    setRandomStatus();

});

client.on("guildCreate", () => {

    // Fired every time the bot is added to a new server

    updateStatus();

});

client.on("guildDelete", () => {

    // Fired every time the bot is removed from a server

    updateStatus();

});

function setRandomStatus() {

    chosenMessageIndex = Math.floor(Math.random() * statusMessages.length);

    // Set the random status message. If "guildSize" is in the status,

    // replace it with the actual number of servers the bot is in

    let statusMessage = statusMessages[chosenMessageIndex].replaceAll('{guildSize}', client.guilds.cache.size);

    client.user.setActivity(statusMessage);

}

function updateStatus() {

    // Check if the displayed status contains the number of servers joined.

    // If so, the status needs to be updated.

    if (statusMessages[chosenMessageIndex].includes('{guildSize}') {

        let statusMessage = statusMessages[chosenMessageIndex].replaceAll('{guildSize}', client.guilds.cache.size);

        client.user.setActivity(statusMessage);

    }

}

你的问题在这里：

var index = Math.floor(Math.random() * (status_list.length - 1) + 1);

这将每次都声明相同的，这就是它不更新的原因

每次将我的机器人添加到新服务器时，我都希望它刷新状态。

这就是您（无意）错过的。你想要做的是，正如你已经做过的那样，使用setInterval(). 无论数字是否更改，这都会每隔一段时间刷新一次状态。您不必确保它已更改，因为它对您的实例的负载很小。

现在，尝试遵循以下代码：

bot.on('ready', async () => { // async is recommended as discord.js generally uses async/await.

  // Logs in the console that the bot is ready.

  console.log(`${bot.user.username} is now ready!`);

  // Rather than using an array, which is generally harder to use, manually set the variables instead.

  const status = `stuff on ${bot.guilds.cache.size} servers.`

  // Set the Interval of Refresh.

  setInterval(async () => { // Again, async is recommended, though does not do anything for our current purpose.

    // Set the activity inside of `setInterval()`.

    bot.user.setActivity(status, { type: "LISTENING" });

  }, 15000) // Refreshes every 15000 miliseconds, or 15 seconds.

});

这应该可以满足您的需要，但正如我从您的代码中看到的那样，您试图随机状态？如果是这样，请改为执行以下操作：

bot.on('ready', async () => {

  console.log(`${bot.user.username} is now ready!`);

  // In this one, you will need to make an array. Add as many as you want.

  const status_list = [`stuff on ${bot.guilds.cache.size} servers.`, `stuff on ${bot.channels.cache.size} channels.`];

  // Now randomize a single status from the status_list. With this, you have singled out a random status.

  const status = Math.floor(Math.random() * status_list.length);

  setInterval(async () => {

    bot.user.setActivity(status, { type: "LISTENING" });

  }, 15000)

});

现在，如果你想要一个不断变化的（不是随机的）状态，你可以使用下面的代码：

bot.on('ready', async () => {

  console.log(`${bot.user.username} is now ready!`);

  const status_list = [`stuff on ${bot.guilds.cache.size} servers.`, `stuff on ${bot.channels.cache.size} channels.`];

  // Create a new `let` variable, which can be assigned to, say, `count`.

  // We start from 0 so that it doesn't mess up.

  let count = 0;

  setInterval(async () => {

    // Check if the count is already the length of the status_list, if it is, then return to 0 again. This has to be done before the `status` variable has been set.

    if (count === status_list.length + 1) count = 0;

    // Define Status by using the counter

    const status = status_list[count];

   

    // Add the counter by 1 every time the interval passed, which indicates that the status should be changed.

    count = count + 1;

    bot.user.setActivity(status, { type: "LISTENING" });

  }, 15000)

});

Answer 3

我认为它应该是这样的：

bot.on('ready', () => {

  console.log(`${bot.user.username} is now ready!`);

  setInterval({

    bot.user.setPresence({

      activity: {

        name: `Running in ${bot.guilds.cache.size} servers.`,

        type: "LISTENING"

      }

    });

  }, 15000);

});

这应该显示机器人在每个时间间隔内有多少台服务器。
