Discord.js 等级系统

Question

我的 'problem' 更多的是我想添加的功能，我使用了这个指南： https://anidiots.guide/coding-guides/sqlite-based-points-system 我稍微更改了代码以主要为您提供随机数量的 XP，我正在寻找编辑需要多少 XP 才能升级。

现在它是一个静态数量，升级需要 5000。我试图让它每次升级时额外增加5000升级所需的数量。

目前，它是这样工作的：

Level 1 to 2 = 5000 total XP needed

Level 2 to 3 = 10000 total xp needed

目前，每级之间升级所需的金额始终为5000。

这就是我希望它的工作方式：

Level 1 to 2 = 5000 total XP needed

Level 2 to 3 = 15000 total XP needed

2 级需要 5000，3 级需要 10000，依此类推（每次升级需要的数量增加 5000）

我花了 2 个小时的大部分时间尝试不同的事情，主要是查看完全超出我理解范围的代码。我相信做这样的事情会奏效，但我不知道它是否正确

if (score.level == '1') {
    nextLevel = 5000
}
if (score.level == '2' {
    nextLevel = 10000
}

我非常怀疑这是正确的，否则我的消息事件会很长，因为我计划有 100 个级别

完整代码：

    let score;
    if (message.guild) {
        score = bot.getScore.get(message.author.id, message.guild.id);
        if (!score) {
            score = {
                id: `${message.guild.id}-${message.author.id}`,
                user: message.author.id,
                guild: message.guild.id,
                points: 0,
                level: 1,
            };
        }
        const xpAdd = Math.floor(Math.random() * 10) + 50;
        const curxp = score.points;
        const curlvl = score.level;
        const nxtLvl = score.level * 5000;
        score.points = curxp + xpAdd;
        if (nxtLvl <= score.points) {
            score.level = curlvl + 1;
            const lvlup = new MessageEmbed()
                .setAuthor(
                    `Congrats ${message.author.username}`,
                    message.author.displayAvatarURL()
                )
                .setTitle('You have leveled up!')
                .setThumbnail('https://i.imgur.com/lXeBiMs.png')
                .setColor(color)
                .addField('New Level', curlvl + 1);
            message.channel.send(lvlup).then(msg => {
                msg.delete({
                    timeout: 10000,
                });
            });
        }
        bot.setScore.run(score);
    }

代码按原样工作正常，符合预期，但原样不是很好，因为从 30-31 级开始没有奖励，因为它与从 1 级获得相同数量的 XP -2

Answer 1

这里有一个小公式可以解决问题（如果我理解正确的话）：

const nxtLvl = 5000 * (Math.pow(2, score.level) - 1);

升级需要满足以下 xp 要求：

1->2:  5000
2->3:  15000
3->4:  35000
4->5:  75000
5->6: 155000

Answer 2

尝试这样的事情：

const levels = [0, 5000, 15000, 30000, 50000, 75000];
....
nextLevel = levels[score.level];

@Dan 你是这个意思:

nextLevel = 5000 * Math.round( score.level * (score.level + 1) / 2 );

这是我正在使用的代码但问题是我无法添加或删除 XP 我也是用 Scratch 做的，所以我很生气理解这个
