命令超时|Discord.js [英] Command Timeout | Discord.js

问题描述

目前我有以下内容：

const Discord = require("discord.js");
const PREFIX = ",";
const token = "my token";
var bot = new Discord.Client();
bot.on('ready', () => {
    bot.on('message', message => {
        if (!message.content.startsWith(PREFIX)) return; //if not command ignore message

        var args = message.content.substring(PREFIX.length).split(" "); //splits commands so each word = pos in array

        switch (args[0].toLowerCase()) { //not case-sensitive anymore

            case "hello":
                message.channel.send("hello");
                break;

             //rest of the commands

我想限制命令"，hello"的使用。我希望用户每次输入"你好"时都有10秒的超时。如果用户在此冷却之前输入命令，它将发送一条消息，说明谁上次使用了该命令，以及冷却时间保持了多长时间。

我希望结果是这样的：

User1:          ,hello
Bot:             hello

(After 1 second)

User2:          ,hello
Bot:            User1 has already used this command, please wait another 9 seconds to use it again

(After 9 seconds)

User 2:         ,hello
Bot:            hello

感谢所有的帮助。 谢谢，

推荐答案

您需要存储上次使用该命令的日期，然后相应地分叉该流。若要同时显示上次使用该命令的用户，您需要将该信息与时间戳一起存储。

这里有一个基于您的示例：

const Discord = require("discord.js");
const PREFIX = ",";
const token = "my token";
const bot = new Discord.Client();

let lastHelloCommandDate, lastHelloCommandUser;

bot.on('ready', () => {
    bot.on('message', message => {
        if (!message.content.startsWith(PREFIX)) return; //if not command ignore message

        var args = message.content.substring(PREFIX.length).split(" "); //splits commands so each word = pos in array

        switch (args[0].toLowerCase()) { //not case-sensitive anymore

            case "hello":
                hello(message);
                break;

             //rest of the commands
  }}})
})

function hello(message) {
  const now = new Date();
  if (now - lastHelloCommandDate > 10 * 60 * 1000) {
    // It's been more than 10 mins
    message.channel.send("hello");
    lastHelloCommandDate = now;
    lastHelloCommandUser = message.sender;
  } else {
    // It's been less than 10 mins
    // send a direct message to the user
    // i don't know if message.sender exists, check the api
    message.sender.send(`Command last used by ${lastHelloCommandUser}`);
  }

}

对此示例进行了修改，以便将命令存储在单个对象中并对其进行动态检查。这样就不需要SWITCH语句。

const Discord = require("discord.js");
const PREFIX = ",";
const token = "my token";
const bot = new Discord.Client();

let lastHelloCommandDate, lastHelloCommandUser;

bot.on('ready', () => {
    bot.on('message', message => {
        if (!message.content.startsWith(PREFIX)) return; //if not command ignore message

        var args = message.content.substring(PREFIX.length).split(" "); //splits commands so each word = pos in array
        const command = args[0].toLowerCase();

        if (!commands[command]) {
          throw new Error(`Unknown command supplied: ${command}`);
        }
        commands[command](message);
  }}})
})

const commands = {
  hello: message => {
    const now = new Date();
    if (now - lastHelloCommandDate > 10 * 60 * 1000) {
      // It's been more than 10 mins
      message.channel.send("hello");
      lastHelloCommandDate = now;
      lastHelloCommandUser = message.sender;
    } else {
      // It's been less than 10 mins
      // send a direct message to the user
      // i don't know if message.sender exists, check the api
      message.sender.send(`Command last used by ${lastHelloCommandUser}`);
    }
  }
};
