Discord.js Ping命令

Question

我正在尝试为我的机器人创建一个ping命令，这是我的代码

client.on('message', message => {
  if (message.content === '+ping') {  
    message.channel.send(`?Latency is ${m.createdTimestamp - message.createdTimestamp}ms. API Latency is ${Math.round(client.ws.ping)}ms`);
  }
});

然而，我最终得到了以下错误

C:\Users\ujjwa\Desktop\All Disc\Test all\index.js:236
    message.channel.send(`?Latency is ${m.createdTimestamp - message.createdTimestamp}ms. API Latency is ${Math.round(client.ws.ping)}ms`);
                                     ^

ReferenceError: m is not defined

    at Receiver.receiverOnMessage (C:\Users\lol\Desktop\All Disc\Test all\node_modules\ws\lib\websocket.js:797:20)

你能帮帮我吗？

Answer 1

您需要使用Date.now() - message.createdTimestamp来获取延迟。

client.on('message', message => {
  if (message.content === '+ping') {  
    message.channel.send(`?Latency is ${Date.now() - message.createdTimestamp}ms. API Latency is ${Math.round(client.ws.ping)}ms`);
  }
});

Answer 2

client.on('message', message => {
  if (message.content === prefix + 'ping') {
  message.channel.send('Loading data').then (async (msg) =>{
    msg.delete()
    message.channel.send(`?Latency is ${msg.createdTimestamp - message.createdTimestamp}ms. API Latency is ${Math.round(client.ws.ping)}ms`);
  })
  }
});

我使用这个作为我的Ping命令(如果我犯了任何错误，很抱歉，我在过去的两天里才学会了JavaScript )

module.exports={
    name:'ping',
    description: "Command ini digunakan untuk Ping",
    execute(message, args){
        message.channel.send(`?Latency is ${Date.now() - message.createdTimestamp}ms`);
        }
      };
