Discord Bot 发送多条消息，但我只希望它发送一条

Question

My Discord Bot is sending multiple messages but I just want it to send one message.

bot.on('message', msg=>{
    if(msg.content == "hello"){
        msg.channel.send('Hello!');
    }
})

Answer 1

Your code makes your bot send Hello! to every message, including the Hello! message your bot just sent. This means your bot will send Hello! to a message, receive the Hello! message it just sent, send another message, etc.

You probably want to ignore messages that your bot sent, or generally ignore messages from all bots:

bot.on('message', msg=>{
  // Ignore messages from your bot
  if (msg.author.id === bot.user.id) return
  // Or ignore messages from all bots
  // if (msg.author.bot) return

  // rest of your code...
})
