How to Fix the on_message Command Blocking Other Commands in Discord.py

If you're developing a Discord bot using Python's discord.py, you might run into a common issue: your custom on_message command prevents other commands from functioning correctly. This can be frustrating, especially when you want to implement custom features while retaining the ability to use default commands.

In this guide, we'll tackle the problem of how the on_message event can hinder other commands and explore an effective solution to this issue.

Understanding the Problem

When using the on_message function, you're effectively overriding the default behavior of message processing in your bot. This means that any commands that would normally be recognized are no longer being processed, leading to a disruption in the expected functionality of your bot.

In simpler terms, by creating your own on_message event, you're telling the bot to ignore its built-in command processing features unless you specifically tell it otherwise.

For instance, consider the following code snippet:

This code successfully deletes messages that start with an exclamation mark (!). However, it also prevents any commands that start with ! from being executed.

The Solution: Adding Command Processing

To restore the functionality of the other commands while still implementing your custom behavior, you need to explicitly call the function that processes commands within your on_message function.

Revised Code

Here’s how to modify your on_message function correctly:

Breakdown of the Solution

Message Deletion: The first part of the function checks if the message starts with !. If true, it deletes that message.

Processing Commands: By adding await client.process_commands(message) at the end of the function, you ensure that after your custom behavior is executed, the bot will continue to recognize and process any commands that are sent in the chat.

Maintaining Functionality: This way, your custom message deletion feature does not impede the execution of other commands.

Why This Works

The client.process_commands() function tells the bot to continue processing any commands that would typically be activated by the incoming message. This means that your bot can efficiently perform multiple tasks without losing any pre-existing command functionality.

Conclusion

By understanding the underlying mechanics of the on_message event, you can effectively implement features without blocking other commands in your Discord bot. Remember, anytime you override this function, it’s essential to integrate the command processing call to maintain the full spectrum of your bot’s capabilities.
