Discord.py Bot 执行命令两次

Question

我的机器人执行这些命令，其中包括 await bot.process_commands(ctx) & 等待 bot.process_commands(消息)。我该如何修复？

#playing a game status

@bot.command()

Answer 1

on_message 将在您在 Discord 频道或 DM 聊天中收到消息时执行（链接）。所以你只需要一个 on_message 函数

我不知道为什么你的代码有多个 on_message 所以有一些方法可以修复它。

• 将所有相关内容合并到一个on_message中，

@bot.event
async def on_message(message: discord.Message):
    #Do everything related in here

• 为专用案例使用专用API，您可以阅读以获取更多信息Discord API

如果您需要创建另一个要使用 on_message 执行的函数，那么您需要这样做。

@bot.listen('on_message')
async def my_message(message):
    print('two')

Answer 2

您遇到的问题是bot.process_commands。它的作用是处理来自消息的命令。在内部，它在默认的 on_message 中使用来使命令运行。当你仔细想想，这是有道理的。但是，当您覆盖默认的 on_message 时，它会覆盖 bot.process_commands，因此您的命令将停止工作。

（实际上，Discord.py 的官方常见问题解答涵盖了这一点：为什么 on_message 会让我的命令停止工作？）

为了让我们的命令再次工作，我们仅添加一个bot.process_commands 到 on_message 的末尾。但在您的代码中，您运行了两个 on_message 事件和两个 bot.process_command，因此我们处理命令两次。这就是为什么你的命令会起作用两次。只需从自定义 on_message 事件中删除一个事件或根本不使用它即可。
