【问题描述】：

我想做以下事情：

我将使用命令 (!setupembed) 创建一个嵌入这将在特定频道中创建嵌入并添加对嵌入的反应。有一个名为 Codes 的嵌入字段，它计算 .txt 的行数

每当用户对嵌入的表情符号做出反应时，他都应该得到一个带有存储在 .txt 中的代码的 DM 现场计数器：代码应减少 1 到目前为止，这就是我的代码：

bot.on("ready", () =>{
    console.log("Succesfully started the tools bot");
})




    bot.on("message", message=>{

        let args = message.content.substring(prefix.length).split(" ");
        var mcodes = fs.readFileSync('./text.txt').toString().split("\n").length;
        const embed = new Discord.MessageEmbed().setTitle("Codes").setDescription("Pls React").addField("Instock", "`" + mcodes + "`")




        switch(args[0]){

             case "code": 
             let codetext = message.content.replace(prefix + "code", "")
                fs.appendFile("./text.txt", codetext + "\n",(err)=>{
                if (err) throw err;
                      message.channel.send("message written")
                 })
                const newembed = new Discord.MessageEmbed()
                .setTitle("CODES")
                .addField("Instock", "`" + snscodes + 1 + "`")
                message.edit(embed)
            break;


            case "getcode":
            let getcode = fs.readFileSync("./text.txt", "utf8", (err)=>{
                if (err) throw err;
            })
            var code_array = getcode.split("\n")
                message.channel.send(code_array[0])
            let spliced = code_array.splice(0);
                fs.writeFile("./text.txt", "utf8", (err)=>{
                if (err) throw err;
                 })
            break;


            case "setupembed":
                bot.channels.cache.get("698221179810349187").send(embed).then(sent => {
                        sent.react("????️")
                    })

            break;






        }
    })
    ```

I already tried to write the part bymyself but i cant get it to work thats my attempt: (see answers)

  case "setupembed": 
        const embed = new Discord.MessageEmbed()
            .setTitle("Codes")
            .addField("CODES", "`" + mcodes + "`")
            bot.channels.cache.get("698221179810349187").send(embed)
            .then(sent => {
                sent.react("?️")
            })
            const filter = (reaction, user) => {
                return reaction.emoji.name === '?️' && user.id === message.author.id;
            }; 
            const collector = message.createReactionCollector(filter, { time: 15000 });
            collector.on('collect', (reaction, reactionCollector) => {
                let getcode = fs.readFileSync("./text.txt", "utf8", (err)=>{
                    if (err) throw err;
                })
                var code_array = getcode.split("\n")
                message.author.send(code_array[0])
                let spliced = code_array.splice(0);
                fs.writeFile("./text.txt", "utf8", (err)=>{
                    if (err) throw err;
                })
            });
            collector.on('end', collected => {
                console.log(`Collected ${collected.size} items`);
            });
            break;
    ```
