【中文标题】Node.js + Discord.js:无法读取未定义的属性“类”【英文标题】:Node.js + Discord.js: Cannot read property 'class' of undefined 【发布时间】:2020-12-01 09:36:01 【问题描述】:我对变量有疑问。我正在开发一个 Discord RPG 机器人,但遇到了玩家数据问题。当我使用控制台启动机器人并发送消息以构建我的统计信息时,控制台将返回
C:\Users\willi\OneDrive\Desktop\discord-bot\homies.js:395
player[id].class = reply;
^
TypeError: Cannot set property 'class' of undefined
我使用下面的代码。这是整个程序的一个片段。这需要的所有文件都存在。
const Discord = require('discord.js');
const prefix, token = require('./config.json');
const client = new Discord.Client();
const fs = require('fs');
const player = fs.readFileSync('user.json', 'utf-8');
client.on('message', message =>
var id = message.author.id;
if (player[id] === undefined)
player[id] =
username: message.author.username,
class: undefined,
xp: 0,
lvl: 1,
xpReq: 100 + this.lvl * 75,
hp: 0,
maxHp: 0,
str: 0,
def: 0,
int: 0,
dex: 0,
luck: 0,
mana: 0,
maxMana: 0,
equip:
top: undefined,
bottom: undefined,
hand: undefined,
acc1: undefined,
acc2: undefined
,
spellcaster: undefined,
spells: []
;
var authorVerifier = m => m.author.id === id;
var classAnswer = message.channel.createMessageCollector(authorVerifier, time: 300000, max: 1 );
var classInterpreter = function(reply)
if (reply !== 'fighter' && reply !== 'adventurer' && reply !== 'mage'
&& reply !== 'healer' && reply !== 'rouge' && reply !== 'tank')
return message.channel.send('That was not a valid class!');
else
player[id].class = reply;
fs.writeFileSync('user.json', player[id], (err) =>
if (err) throw err;
);
classAnswer.on('collect', m => classInterpreter(m.content));
);
我尝试用message.author.id
替换id
,但无济于事。请帮忙!
【问题讨论】:
【参考方案1】:您可以通过将播放器数组传递给
classInterpreter
来解决它 函数,并用它来设置player[id].class
的值。
classAnswer.on('collect', m => classInterpreter(m.content, player));
