JS开发Discord同人机器人时多聊天功能模块调用问题咨询

存在的基础错误 #

1. 模块导入导出逻辑错误
   • chat.js末尾两次赋值module.exports会导致前一次被覆盖，且不能导出文件名chat.js，应导出你定义的函数本身
   • Greetings是chat.js内定义的函数，不是独立第三方包，index.js中require('Greetings')会直接报错找不到模块
2. 参数未传递问题
   chat和Greetings函数内使用的message对象是discord.js触发message事件时传入的参数，你没有将它传入两个函数，运行时会直接报message is not defined错误
3. 函数未调用问题
   index.js的message事件回调里只处理了!ping指令，没有调用你写的chat、Greetings函数，相当于你Unity里写了Update但没写调用chat的逻辑，自然不会触发对应回复
4. discord.js版本兼容问题（如果用v12及以上版本）
   v12之后discord.js把大部分集合操作移到了cache下：
   • message.guild.roles.find要改为message.guild.roles.cache.find
   • message.member.addRole要改为message.member.roles.add

修正后的代码 #

chat.js

// 函数接收message作为参数
function chat(message)
{
    //Character dialogue. 
    //This is to get more information about characters, or specific reactions to character names.

    }

        message.reply("WHERE?!");
    }

    //Info about Kameo
    if (message.content == "Hey Meepo, can you tell me about Kameo?") {
        message.reply("Sure can! What do you wanna know?\n Kameo Character Info.\n Kameo's Skills.\n Kameo's Origins.")
    }

    if (message.content == "Kameo's Skills.") {
        message.reply("Kameo is basically the jock of the family with twice the charm, she can dropkick a baby and people would still love her!\n \n She can fly pretty fast but can't really get off the ground. That said, large gaps are a pretty big problem for her too.\n \n When fighting on her own, Kameo can do this flip kick, like WHAPOW!\n \n and....that's pretty much it actually.")
    }

    //if the user makes a typo:
    if (message.content == "Kameo's kills.") {

Okay, here it says Kameo came from the Twycross Village, her Gramps, Terramus, is the Cheiftan and he...oh, \n \n -yeah okay he died after Thorn smacked him.\n Solon got real mad and used The Ultimate Curse, then HE died and the Warriors and Wotnot were kaput.\n \n 5 Sprites got captured, 5 were pro at hide n seek and took baby Kameo back to the Royal Fameo, where Theena adopted her and started playing favourites.\n  \nWait, so that means Kameo's parents are still alive, right? \n \nHmmm...")

const PREFIX = '!';

bot.on('message', async message =>

    // 先跳过机器人自己发的消息，避免死循环
    if(message.author.bot) return;

    let args = message.content.substring(PREFIX.length).split(" ");

    switch (args[0])
    {
        case 'ping':
            message.reply('pong');
            break;
    }

    // v12+版本用下面这句
    // var role = message.guild.roles.cache.find(role => role.name === "user");
    var role = message.guild.roles.find(role => role.name === "user");

    // 调用你写的逻辑，把message作为参数传入
    Greetings(message);
    chat(message);

});

bot.login(token);

额外优化建议 #

后续可以把不同类别的指令拆成单独的js文件，比如对话类放chat.js，问候类放greet.js，角色查询类放character.js，统一导出后在index.js里调用，维护会更方便。
