我如何在 discord js 中使用异步功能来制作问题游戏？

Question

我想制作一个不和谐的机器人，如果我在特定时间输入完成，它会问我一个问题，如果它的答案应该说你赢了，但如果它达到 7 秒，它应该说时间到但我没有知道有时它会按时间向频道发送垃圾邮件，我该如何解决，请我被困在那里 8 小时？

/* === countries image === */

var   kurdistan = "https://upload.wikimedia.org/wikipedia/commons/thumb/3/35/Flag_of_Kurdistan.svg/800px-Flag_of_Kurdistan.svg.png";
var   catalonia = "https://upload.wikimedia.org/wikipedia/commons/thumb/c/ce/Flag_of_Catalonia.svg/810px-Flag_of_Catalonia.svg.png";

             embed.setTitle('Flag guesser');
             embed.setDescription('which countries flag does this belong?');
             embed.setImage(obj[ranImg]);
             embed.setColor(0x3aeb34);
             embed.setFooter('this game provided by by me');
             embed.setTimestamp();
             message.channel.send(embed).then(() => {

              message.channel.awaitMessages(filter, { max: 1, time: '7000', errors: ['time'] })
               .then(collected => {  
//when it gives me the image and I write the correct answer of the obj[ranImg] it doesn't says you win all the time it says try again ???????????????????????????????? 
                  if (collected.first().content === obj[ranImg]) {
                    return message.channel.send(':white_check_mark: You win!') //they won 
                  } else {
                    return message.channel.send(`:x: Oooh close! Try again!`); // they lost 
                  }
               })
               .catch(collected => {
                  return message.channel.send('times up! no answers were collected!');
               });
            });
        }
    }
  );

消息收集器很难，而且你真的很接近。你不需要定义 awaitMessages，而且 await 已经是异步的，所以你不需要在 #awaitMessages 之前输入 async。此外，您需要一个#then 来引导到#awaitMessages。

此外，如果抛出由errors: ['time'] obj 定义的错误，则收集器有#catch 系统的概念。

maxMatches 已过时，在 v12 中已更改为 max

最后，我将结合以上所有内容来修复您的代码：

client.on('message', async message => {
  if(message.author.bot) return; //have this here so the command does as little as possible before returning

        const ranImg = Math.floor(Math.random() * obj.length); 
        if(message.content === 'flag') {
           const embed = new Discord.MessageEmbed();
           embed.setTitle('Flag guesser');
           embed.setDescription('which countries flag does this belong?');
           embed.setImage(obj[ranImg]);
           embed.setColor(0x3aeb34);
           embed.setFooter('this game provided by by me');
           embed.setTimestamp();
           message.channel.send(embed).then(() => {
            let filter = m => m.author.id === message.author.id;

            message.channel.awaitMessages(filter, { max: 1, time: '7000', errors: ['time'] })
             .then(collected => {
                if (collected.first().content === obj[ranImg]) {
                  return message.channel.send(':white_check_mark: You win!') //they won 
                } else {
                  return message.channel.send(`:x: Oooh close! Try again!`); // they lost 
                }
             })
             .catch(collected => {
                return message.channel.send('times up! no answers were collected!'); // if the timer of 7000ms elapses, catch here
             });
          });
      }
  }
);
