问题描述
我的 discord 机器人中有一个头像命令.当用户使用 h.avatar 时，它会输出他们的头像，效果很好.每当他们尝试使用 h.avatar @user 时，什么都没有发生.
这是我的代码:
I have an avatar command in my discord bot. When the user uses h.avatar, it outputs their avatar, which works fine. Whenever they try to use h.avatar @user, nothing happens.
Here is my code:
} if (message.content.startsWith(config.prefix + "avatar")) {
if (!message.mentions.users.size) {
const avatarAuthor = new Discord.RichEmbed()
.setColor(0x333333)
.setAuthor(message.author.username)
.setImage(message.author.avatarURL)
message.channel.send(avatarAuthor);
let mention = message.mentions.members.first();
const avatarMention = new Discord.RichEmbed()
.setColor(0x333333)
.setAuthor(mention.user.username)
.setImage(mention.user.avatarURL)
message.channel.send(avatarMention);
推荐答案
你有一个检查 if (!message.mentions.users.size) { 这使得命令只有在你不这样做的时候才会运行提到某人.您需要在代码中使用 else { 或执行以下操作:
You have a check if (!message.mentions.users.size) { which makes the command run only if you do not mention somebody. You either need to use an else { in your code or do:
if (message.content.startsWith(config.prefix + 'avatar')) {
const user = message.mentions.users.first() || message.author;
const avatarEmbed = new Discord.RichEmbed()
.setColor(0x333333)
.setAuthor(user.username)
.setImage(user.avatarURL);
message.channel.send(avatarEmbed);
}
const user = message.mentions.users.first() ||message.author; 尝试获取提到的用户，但如果找不到任何人，它将使用作者使用的.
The const user = message.mentions.users.first() || message.author; tries to get the user that was mentioned but if it does not find anyone it will use the author's used.
也可以这样使用:
if (!message.mentions.users.size) {
message.channel.send('Nobody was mentioned');
return;
}
// continue command here, after guard clause
