为什么别名没有被执行? [英] why are aliases not getting executed?

问题描述

您好，我在 discord.js 中遇到了别名问题，别名不起作用，我不知道为什么?

Hello, I'm having an issue with aliases in discord.js the aliases don't work, I don't know why?

client.on('message', message =>{
    // Exit when the message from the bot
    if (!message.content.startsWith(prefix) || message.author.bot) return;

    const args = message.content.slice(prefix.length).trim().split(/ +/);
    const commandName = args.shift().toLowerCase();

    if (!client.commands.has(commandName)) return;

    const command = client.commands.get(commandName) || client.commands.find(cmd => cmd.aliases && cmd.aliases.includes(commandName));

    try {
        command.execute(message, args, commandName, client, Discord);
    } catch (error) {
        console.error(error);
        message.reply('there was an error trying to execute that command!');
    }
});

推荐答案

不能使用别名，因为你放了

You can’t use aliases because you put

if(!client.commands.has(commandName)) return;

如果您尝试使用别名或其他任何不在您的 client.commands 键中的东西，这将返回 false.删除此行并改用此行:

This returns false if you try an alias, or anything else that isn’t in your client.commands keys. Remove this line and use this instead:

const args = message.content.slice(prefix.length).trim().split(/ +/);
const commandName = args.shift().toLowerCase();
const command = client.commands.get(commandName) || client.commands.find(cmd => cmd.aliases?.includes(commandName));
if(!command) return;
//...

这会查找命令首先，然后如果没有找到命令、名称或别名，则返回

This looks for the command first and then if no command is found, name or alias, it returns
