目前我有这样的：命令超时| Discord.js
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“你好”的用法。我希望每次用户输入“hello”时都会有10秒的超时时间。如果用户在冷却前输入命令，它会发送一条消息，说明谁最后使用了该命令，以及冷却时间还剩多长时间。
这就是我想要的结果看起来像：
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
所有帮助表示赞赏。 谢谢，

您需要存储该命令的最后日期，然后相应地分流。为了显示最后一次使用该命令的人员，您需要将该信息与时间戳一起存储。
下面是一个例子基于你：
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}`);
}
}
将该样品再加工，使得命令存储在一个单独的对象和动态检查。这消除了对switch语句的需要。
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}`);
}
}
};
