Question

我试图通过在达到某个级别时自动将用户添加到角色来向我的不和谐机器人xp-system添加功能。

我一直在尝试所有我能想到的解决方案，但似乎没有一个起作用。

尝试过：

addrankup.addRole(fullmember).catch(console.error);

let addrankup.addRole(fullmember).catch(console.error);

addrankup.addRole(fullmember.id).catch(console.error);

当用户达到设定水平以自动获得排名时预期：

let xpAdd = Math.floor(Math.random() * 5) + 10;
console.log(xpAdd);

if (!xp[message.author.username]) {
  xp[message.author.username] = {
    xp: 0,
    level: 1
  };
}

let curxp = xp[message.author.username].xp;
let curlvl = xp[message.author.username].level;
let nxtLvl = xp[message.author.username].level * 200;
xp[message.author.username].xp = curxp + xpAdd;
if (nxtLvl <= xp[message.author.username].xp) {
  xp[message.author.username].level = curlvl + 1;

  message.channel.send("Level Up!").then(msg => {
    msg.delete(5000)
  });
}

if (curlvl <= xp[message.author.username].level) {
  xp[message.author.username].level = "2";

  let addrankup = message.mentions.members.first();
  let fullmember = message.guild.roles.find(`name`, "Full Member");
  addrankup.addRole(fullmember.id).catch(console.error);
  message.channel.send("You have received a new role!").then(msg => {
    msg.delete(5000)
  });
}

fs.writeFile("./xp.json", JSON.stringify(xp), (err) => {
  if (err) console.log(err)
});

但这是控制台告诉我的：

Answer 1

该错误告诉您addrankup未定义，这反过来意味着message.mentions.members.first();不返回任何内容。我的猜测是，而不是

let addrankup = message.mentions.members.first();

您正在寻找

let addrankup = message.member;

达到特定级别时，用户的addRole问题
