是否可以制作一个专用于某个作者的变量Discord.js？

Question

我正在制作一个商店机器人，我运行遇到了一些 SetInterval 错误。我想让每个变量都有用户的 id，所以当我运行一个不同的命令时，它会知道停止哪个间隔。（如果这有意义的话）。这是我的代码：

if(message.content.startsWith(`!open`) {
    var cashier1[message.author.id] = function () {
        BalanceJSON[message.author.id].bal += 10
        Fs.writeFileSync(`./DB/balance.json`, JSON.stringify(BalanceJSON));
    }
    setInterval(cashier1[message.author.id], 5000);
}

所有这些代码都在 bot.on('message', message => { })

我想用 clearInterval(cashier1[message.author.id])

停止某个玩家的间歇

Answer 1

函数setIntervalreturns a unique id which can be used to clear the interval again (See the example for more information).

您的问题的解决方案是将间隔的唯一 ID 存储在某个对象或数据库中，并使用它再次清除间隔。请参阅下面的示例代码：

// Create an object to store the intervals.
const cashierIntervals = {};

// Inside your message handler.
// Some dummy if statement for demonstration purpose.
if (message.content === 'setInterval') {
  // Create the setInterval and store the unique id in the cashier intervals object.
  // You should probably add more checks to see if there is already an interval stored for this author id etc.
  cashierIntervals[message.author.id] = setInterval(() => {
    BalanceJSON[message.author.id].bal += 10;
    Fs.writeFileSync(`./DB/balance.json`, JSON.stringify(BalanceJSON));
  }, 5000);
} else if (message.content === 'clearInterval') {
  // Clear the interval based on the author id.
  // Again, probably add more checks to see if the author id has an interval stored etc.
  clearInterval(cashierIntervals[message.author.id]);

  // Delete the stored interval entry from the global intervals object.
  // Not necessary but it keeps the intervals object small.
  delete cashierIntervals[message.author.id];
}

Answer 2

创建一个以 id 作为键的对象。你的值将是你想要间隔的函数

您的主文件：

const cashier1 = {
   // Template for your key:values
   '999999999': yourRepeatingFunction(),
}

// Lets say message.author.id returns '999999999'
// Doing setInterval(cashier1[message.author.id], 5000) Will call yourRepeatingFunction()
