问题描述

所以，有一天我使用 TeamViewer 连接到我的 RPi3 并告诉它重新启动.完成后，我连接到 pi，启动了 bot，它看起来正常启动.

So, one day I was using TeamViewer to connect to my RPi3 and told it to reboot. As soon as it finished, I connected to the pi, started the bot, and it looked like it was starting up properly.

当我在 discord 上发送命令时，机器人没有响应.机器人仍在运行.

When I went to send a command on discord, the bot didn't respond. The bot is still running though.

我尝试更改一些代码，但没有任何改变.

I tried changing some of the code, but nothing changed.

代码如下:

[REMOVED]

可能是什么问题?

推荐答案

你的问题是你的 if 语句没有阻塞.

Your problem is lack of blocking of your if statement.

if (message.channel instanceof Discord.DMChannel)
    message.channel.send("``Beep boop! Sorry, I can't respond to direct messages, but you can join the AKAS Gamer's Discord group here: https://discord.gg/QkjQNAr``");
    return

由于缺少括号，您的 return 将始终执行，因为它不是 if 语句的一部分.应该是:

With the lack of bracketing, your return will always execute as it is not part of the if statement. It should be:

if (message.channel instanceof Discord.DMChannel) {
    message.channel.send("``Beep boop! Sorry, I can't respond to direct messages, but you can join the AKAS Gamer's Discord group here: https://discord.gg/QkjQNAr``");
    return
}

C 风格语言中的常见建议是永远不要省略括号.进入那个练习.虽然从技术上讲，单语句条件是允许的，但正如您在此处看到的那样，它稍后会引起头痛.

Common recommendation in C-style languages is to never omit the brackets. Get into that practice. While it is technically allowable for single statement conditionals, it will cause headaches later as you've seen here.
