discord.js 动态添加选项到选项斜杠命令

Question

在我失去的时间里制作一个小不和谐机器人 已经几个小时了，我现在被困住了..

基本上，这是我的命令帮助的一部分

假设我有一个像这样的数组类别：

let categories = [{name: "cat1", value: "cat1"},{name: "cat3", value: "cat3"},{name: "cat2", value: "cat2"}]

有没有一种方法可以导出它们而不必将它们全部写入？ 像这样的东西？

module.exports = {
    data: new discord.SlashCommandBuilder()
        .setName("help")
        .setDescription("Display bot commands")
        .addStringOption(option =>
            option.setName("category")
                .setDescription(`Categories showed in ${prefix}help`)
                .addChoices(categories)),
    start
};

我看到有一个方法 .setChoices 但不知道如何使用它，因为它不接受数组

我尝试使用 .addChoices 和 .setChoices 但没有成功 尝试寻求帮助

Answer 1

我会尝试将其分解为一个函数，然后您可以迭代命令。我认为该文件看起来像这样：

const { SlashCommandBuilder } = require("discord.js");

//Note you could instead pass categories into this function
const fetchMySlashCommandsFunction = () => {
  const categories = [
    { name: "cat1", value: "cat1" },
    { name: "cat3", value: "cat3" },
    { name: "cat2", value: "cat2" },
  ];

const helpBuilder = new discord.SlashCommandBuilder().setName("help") .setDescription("显示机器人命令")

  categories.foreach(cat => {
     helpBuilder.addStringOption((cat.name) =>
          // not sure where prefix is defined in your code?
          .setDescription(`Categories showed in ${prefix}help`)
          .addChoices(cat.name)
      );
  });

  return data;
};
export default fetchMySlashCommandsFunction;

要从此函数检索数据，则为

const data = fetchMySlashCommandsFunction()

感谢@Atomic Goblin，刚刚找到了解决我的问题的方法 仍然不确定这是否是目前最好的解决方案，但它有效

// CATEGORIES ARRAY
const categories = [
    {name:"commands", value:"commands"},
    {name:"weebpack", value:"weebpack"},
    {name:"games", value:"games"},
    {name:"bot", value:"bot"},
    {name:"config", value:"config"}
];
// NEW SLASH COMMAND BUILDER
let data = new discord.SlashCommandBuilder()
    .setName("help")
    .setDescription("Display bot commands");
// ADD NEW OPTION
data.addStringOption(option =>
    option.setName("category")
        .setDescription(`Categories showed in ${prefix}`));
// ADD CHOICES ON FIRST OPTION
categories.forEach(cat =>{
    data.options[0].addChoices(cat);
})
// EXPORTS DATA(slashcommandbuilder) AND START FUNCTION
module.exports = {
    data: data,
    start
};

这里我做了一个函数方法，如果它对某人有帮助的话

// Dinamically add choices from json array
// Input :  discordSlashCommandBuilder()
//          optionName string
//          optionDesc string
//          choices array [{name: "name", value: "value"},{name: "name2", value: "value2"}]
//          isRequired ? boolean
// Return discordSlashCommandBuilder() with option
/**
 * 
 * @param {discord.SlashCommandBuilder} slashCommand 
 * @param {String} optionName
 * @param {String} optionDesc
 * @param {Array} aChoices
 * @param {Boolean} isRequired 
 * @returns 
 */
function slashCommandAddOptionWithChoices(slashCommand, optionName, optionDesc, aChoices, isRequired){
    // get current index
    let idx = slashCommand.options.length;
    // Create new option
    slashCommand.addStringOption(option =>
        option.setName(optionName)
            .setDescription(optionDesc)
            .setRequired(isRequired));
    // Add choices to last option
    // stop after 25 entries (max choices limit)
    let i = 0;
    aChoices.forEach(choice =>{
        if(i === 25) return;
        slashCommand.options[idx].addChoices(choice);
        i++;
    });
    return slashCommand;
}

可能会晚一点重新开放，只是想为可能更容易处理的问题做出贡献：

.addChoices(...categories))
