javascript - 顯示冷卻時間剩餘

我想要顯示冷卻時間剩餘的時間，但我不確定是否可以使用我目前的格式來完成。這可能嗎？或者有沒有更好的方式來使用冷卻？我刪掉了大部分與此無關的程式碼。

let cooldown = new Set();
if(msgObject.content.startsWith("-eat")) {        

    let amount = Math.floor(Math.random() * 2500) + 1;
    let Channel = msgObject.channel.id

    if(Channel != `623195917083738136` && Channel != `623195981919289344` ){//bot test
        msgObject.channel.send('Cannot use command here, ' + msgObject.author)
            .then(msg => {
                (msg as Discord.Message).delete(20000)
                    .catch(console.error);
            })
        return;
    }

    if(cooldown.has(msgObject.author.id)){
        msgObject.channel.send(`You have to wait 3 hours to use this command again!`)
            .then(msg => {
                (msg as Discord.Message).delete(20000)
                    .catch(console.error);
            })
        return;
    }
    if(msgObject.content.startsWith("-eat")){
        cooldown.add(msgObject.author.id)

    }

    setTimeout(() => {
        cooldown.delete(msgObject.author.id)
    }, cdseconds * 1000);

    {let embed = new Discord.RichEmbed()

        .setAuthor(`${msgObject.author.tag}`, msgObject.author.displayAvatarURL) 

        .setDescription(`${msgObject.author}, ${(eat[index1])}${amount} DinoBucks`)

        .setColor("RANDOM");

        msgObject.channel.send(embed)
            .then(msg => {
                (msg as Discord.Message).delete(20000)
                    .catch(console.error);
            })  
        }      
    } 
}

答案＃1

以你目前的設置，這是不可能的。不過，你可以使用類似 Discord.js 指南上的方法：

// a collection of user ids to when (the timestamp) they used the command
const timestamps = new Discord.Collection<string, number>();

if (msgObject.content.startsWith("-eat")) {
    const now = Date.now();
    const cooldownAmount = cdseconds * 1000;

    if (timestamps.has(msgObject.author.id)) {
        const expirationTime = timestamps.get(msgObject.author.id) + cooldownAmount;

        if (now < expirationTime) {
            const timeLeft = (expirationTime - now) / 1000;
            return msgObject.reply(`You have to wait ${timeLeft.toFixed(1)} seconds to use this command again!`)
        }
    }

    // for v11:
    // const embed = new Discord.RichEmbed()
    const embed = new Discord.MessageEmbed()
        .setAuthor(`${msgObject.author.tag}`, msgObject.author.displayAvatarURL)
        // rest of command...

    timestamps.set(msgObject.author.id, now);
    setTimeout(() => timestamps.delete(msgObject.author.id), cooldownAmount);
}

已更新至 Discord.js v13。

答案＃2

以你的冷卻定義格式這是不可能的。我建議你為此使用 discord.collection，有一個很好的範例實作。
