[英]Discord.js why is my help command not working?
我按照 discord.js 的文檔說明創建了一個動態幫助命令。 當我使用 //help 時,它可以正常工作,但例如,//help ping 不是。我不確定為什么會發生這種情況,我已經嘗試了很多方法來解決這個問題,但沒有任何效果。 有什么見解嗎? 下面的代碼:
index.js
// nodejs for filesystem
const fs = require("fs");
// require the discord.js module
const Discord = require("discord.js");
global.Discord = Discord;
// require canvas module for image manipulation
const Canvas = require("canvas");
// link to .json config file
const { prefix, token, adminRole } = require("./config.json");
// create a new discord client
const client = new Discord.Client();
client.commands = new Discord.Collection();
global.client = client;
const commandFiles = fs.readdirSync("./commands").filter(file => file.endsWith(".js"));
// ...
let target;
let targetName;
global.target = "000000000000000000";
global.targetName = "null";
global.adminRole = "738499487319720047";
// 737693607737163796
let hasRun = false;
for (const file of commandFiles) {
const command = require(`./commands/${file}`);
// set a new item in the Collection
// with the key as the command name and the value as the exported module
client.commands.set(command.name, command);
}
const cooldowns = new Discord.Collection();
// event triggers only once, right after bot logs in
client.once("ready", () => {
console.log("Ready!");
console.log(adminRole);
client.user.setActivity("You", { type: "WATCHING" });
});
// for new member join - sends message including attachent
client.on("guildMemberAdd", async member => {
const channel = member.guild.channels.cache.find(ch => ch.name === "welcome");
global.channel = channel;
if (!channel) return;
const canvas = Canvas.createCanvas(700, 250);
const ctx = canvas.getContext("2d");
const background = await Canvas.loadImage("./wallpaper.jpg");
ctx.drawImage(background, 0, 0, canvas.width, canvas.height);
ctx.strokeStyle = "#74037b";
ctx.strokeRect(0, 0, canvas.width, canvas.height);
// Slightly smaller text placed above the member's display name
ctx.font = "28px sans-serif";
ctx.fillStyle = "#ffffff";
ctx.fillText("Welcome to the server,", canvas.width / 2.5, canvas.height / 3.5);
// Add an exclamation point here and below
ctx.fillStyle = "#ffffff";
ctx.fillText(`${member.displayName}!`, canvas.width / 2.5, canvas.height / 1.8);
ctx.beginPath();
ctx.arc(125, 125, 100, 0, Math.PI * 2, true);
ctx.closePath();
ctx.clip();
const avatar = await Canvas.loadImage(member.user.displayAvatarURL({ format: "jpg" }));
ctx.drawImage(avatar, 25, 25, 200, 200);
const attachment = new Discord.MessageAttachment(canvas.toBuffer(), "welcome-image.png");
channel.send(`Welcome to the server, ${member}!`, attachment);
});
// listening for messages.
client.on("message", message => {
hasRun = false;
// if (!message.content.startsWith(prefix) || message.author.bot) return;
// log messages
console.log(`<${message.author.tag}> ${message.content}`);
// create an args var (const), that slices off the prefix entirely, removes the leftover whitespaces and then splits it into an array by spaces.
const args = message.content.slice(prefix.length).trim().split(/ +/);
global.args = args;
// Create a command variable by calling args.shift(), which will take the first element in array and return it
// while also removing it from the original array (so that you don't have the command name string inside the args array).
const commandName = args.shift().toLowerCase();
const command = client.commands.get(commandName) ||
client.commands.find(cmd => cmd.aliases && cmd.aliases.includes(commandName));
if (message.author.id === global.target) {
// more code (excluded because its too long)
}
if (!command) return;
if (command.guildOnly && message.channel.type !== "text") {
return message.reply("I can't execute that command inside DMs!");
}
if (command.args && !args.length) {
let reply = `You didn't provide any arguments, ${message.author}!`;
if (command.usage) {
reply += `\nThe proper usage would be: \`${prefix}${command.name} ${command.usage}\``;
}
return message.channel.send(reply);
}
if (!cooldowns.has(command.name)) {
cooldowns.set(command.name, new Discord.Collection());
}
const now = Date.now();
const timestamps = cooldowns.get(command.name);
const cooldownAmount = (command.cooldown || 3) * 1000;
if (timestamps.has(message.author.id)) {
const expirationTime = timestamps.get(message.author.id) + cooldownAmount;
if (now < expirationTime) {
const timeLeft = (expirationTime - now) / 1000;
return message.reply(`please wait ${timeLeft.toFixed(1)} more second(s) before reusing the \`${command.name}\` command.`);
}
}
timestamps.set(message.author.id, now);
setTimeout(() => timestamps.delete(message.author.id), cooldownAmount);
try {
target, targetName = command.execute(message, command, args, target, targetName);
}
catch (error) {
console.error(error);
message.reply("there was an error trying to execute that command!");
}
});
client.login(token);

message.reply("I've sent you a DM with all my commands!");
})
.catch(error => {

message.reply("it seems like I can't DM you!");
});
}
const name = args[0].toLowerCase();
const command = commands.get(name) || commands.find(c => c.aliases && c.aliases.includes(name));
if (!command) {
return message.reply("that's not a valid command!");
}
data.push(`**Name:** ${command.name}`);

我需要查看您的 ping 命令,並確定錯誤本身,但我認為您的問題出在您的 index.js 文件中。 我為我的機器人遵循了相同的指南,但我沒有遇到這個問題。 在無法看到錯誤和 ping 命令的情況下,這里有一些地方可以幫助您進行故障排除:
Function(arg1, arg2) 和 Function(arg1) 不是一回事。 它們可能命名相同,並且共享一個參數,但是您傳入的 arguments 確定執行哪個,因此如果您傳入兩個 arguments,那么它應該執行第一個 function,而忽略第二個。 如果只傳入一個,那么它應該執行第二個 function,而忽略第一個。
我在您的 try catch 中看到,您正在將大量 arguments 傳遞給命令,但 arguments 幫助接受與您嘗試傳遞的內容不匹配,因此它可能根本看不到 ZDBC11CAA5BDA99F77E6FB4DAD882E,這可以解釋為什么它在沒有 arguments 的情況下工作,但是當你嘗試傳遞一個時失敗。
這是查看錯誤/結果可能會有所幫助的地方,因為您只是說它不能正常工作,您沒有說它做了什么。 如果執行的命令好像沒有 arguments 盡管存在一個,那么這將被視為“無法正常工作”,但如果該命令由於無法正確處理參數而給您一個錯誤,那么問題將是在你的 help.js 命令中
問題可能是它沒有看到您正在談論的命令,不知道您在請求它,或者它無法獲取請求的信息,因為它不存在。
添加 args = global.args; 在我的幫助文件頂部的 modules.export 之后,它解決了這個問題。
