I want to build a Discord bot feature that can echo back messages when users trigger a specific command. The idea is pretty simple but I’m not sure how to implement it properly.
Basically, when someone types something like !echo hello world @friend, I want my bot to respond by posting the same text followed by mentioning the tagged user and adding the current year.
So if a user writes !echo awesome day @buddy, the bot should reply with:
awesome day
@buddy, 2024
I’m working with Python and discord.py library but I’m stuck on how to capture the message content, extract the mention, and format the response correctly. Any help would be great!
parse the command args n handle mentions separately. use ctx.message.mentions to grab mentioned users, then slice the msg content to pull out just the text (minus the command prefix). remember to wrap the echoed text in asterisks for italics!
Focus on parsing the command structure properly. Split the message content after removing the command prefix, then rebuild everything except the mention part for your echo text. Discord.py converts @username patterns into user objects automatically - you can grab them from the mentions list. Watch out for messages without mentions though. I got burned by that when building similar stuff - add a check or you’ll hit errors. Also make sure your bot has permission to mention users in responses, otherwise the formatting breaks.
To implement the echo command, start by using message.content to retrieve the user’s entire message. From there, you can access the mentioned users via message.mentions. It’s important to use user.mention for mentioned users instead of manually manipulating the string. Also, consider potential edge cases such as no mentions or multiple users in the message. You can utilize message.content.split() to isolate the content after the command, ensuring your bot formats the response correctly.
