我希望通過只允許每 60 秒獲得一次 xp 來改進(jìn)我的積分系統(tǒng)。我嘗試了一些東西，但沒有一個真正接近。當(dāng)前的積分獎勵代碼是client.on('ready', () => { // Check if the table "points" exists. const table = sql  .prepare(   "SELECT count(*) FROM sqlite_master WHERE type='table' AND name = 'scores';"  )  .get(); if (!table['count(*)']) {  // create and setup the database correctly.  sql   .prepare(    'CREATE TABLE scores (id TEXT PRIMARY KEY, user TEXT, guild TEXT, points INTEGER, level INTEGER);'   )   .run();  // "id" row is always unique and indexed.  sql.prepare('CREATE UNIQUE INDEX idx_scores_id ON scores (id);').run();  sql.pragma('synchronous = 1');  sql.pragma('journal_mode = wal'); } // get and set the score data. client.getScore = sql.prepare(  'SELECT * FROM scores WHERE user = ? AND guild = ?' ); client.setScore = sql.prepare(  'INSERT OR REPLACE INTO scores (id, user, guild, points, level) VALUES (@id, @user, @guild, @points, @level);' );});client.on('message', (message) => { if (message.author.bot) return; let score; if (message.guild) {  score = client.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,   };  }  score.points++;  const curLevel = Math.floor(0.2 * Math.sqrt(score.points));  if (score.level < curLevel) {   score.level++;   client.channels.cache    .get('738662532700700719')    .send(`${message.author} has leveled up to level **${curLevel}**!`);  }  client.setScore.run(score); } if (message.content.indexOf(config.prefix) !== 0) return; const args = message.content  .slice(config.prefix.length)  .trim()  .split(/ +/g); const command = args.shift().toLowerCase();});
