Introduction

In this article, we will explore how to add options to Slash Commands in Discord using Discord.js v14. We will build upon the concepts learned in the previous video, where we created and handled slash commands. If You haven't watched that video yet, I highly recommend checking it out before proceeding with this tutorial.

Adding Options to Slash Commands

To get started, we need to modify the ready event in our code to make it more reliable and accurate for future testing purposes. We will use a Discord enum instead of a literal STRING. Once we have made this change, we can proceed to add options to our slash commands.

Modifying the Ready Event

In this step, we will require a new module called "events" from discord.js. This small change won't affect the program's output, but it will enhance the accuracy and reliability of the bot during testing. We will replace the string "ready" with "events.client ready" in the ready event.

Adding an Option to the Hello Command

The hello command currently outputs a generic greeting. In this step, we will modify it to check if the user has specified another user to greet. If a user is specified, the bot will say hello to that user. To achieve this, we will add a user option to the hello command. This option will allow users to specify another user to say hi to.

Handling User Input in the Interaction Create Function

Now that we have added the user option to the hello command, we need to handle the user's input. In the interaction create function, we will extract the user option and check if it has been provided. If it has, the bot will greet the specified user. Otherwise, it will give a generic "Hi" greeting.

Testing the Hello Command

At this stage, we can test the hello command in our Discord server. By specifying a user in the command, we can check if the bot correctly greets the specified user. If no user is specified, the bot should give a generic greeting.

Adding a New Command: Add

In this section, we will create a new command called "add" that will allow users to add two numbers together. We will follow a similar process as before, starting with creating the slash command builder and adding number options.

Creating the Slash Command Builder

We will use the slash command builder to create the add command. We will give it a name and description, indicating that it allows users to add two numbers.

Adding Number Options for Addition

To enable the addition of multiple numbers, we will add number options to the command. We will create two options: "first number" and "Second number", both of which will be required. This ensures that the user inputs both numbers.

Computing and Displaying the Result

Once the user inputs the numbers, we need to check if the input is valid and then compute the sum of the numbers. If the input is invalid, the bot will prompt the user to enter a valid number. Otherwise, it will display the sum of the numbers.

Testing the Add Command

With the add command implemented, we can test it in our Discord server. By inputting two numbers, we should receive the sum of those numbers as the output. If the input is invalid or incomplete, the bot will prompt the user to provide a valid number.

Adding the Bye Command

Finally, we will add a bye command that mimics the behavior of the hello command. If a user is specified, the bot will send a personalized goodbye message. Otherwise, it will give a generic salutation. This command adds another level of interaction and friendliness to the bot.

Conclusion

Congratulations! You have successfully learned how to add options to Slash Commands in Discord using Discord.js v14. By following the step-by-step process outlined in this article, you can enhance your bot's interactivity and make it more user-friendly. Be sure to explore more advanced topics in Discord bot development and stay tuned for future tutorials.

FAQ

• Q: How can I test the commands in my Discord server?

  • A: To test the commands, you need to have your bot invited to your server. Once the bot is added, you can use the command prefixes and input the required parameters to test the functionality.

• Q: What happens if a user doesn't provide the required parameters?

  • A: If a user fails to provide the required parameters, the bot will prompt them to enter valid input. This ensures that the commands work as intended and prevent any unexpected errors.

• Q: Can I customize the commands further?

  • A: Yes, you can customize the commands as per your requirements. You can modify the command names, descriptions, and options to suit your bot's functionality. Be sure to refer to the Discord.js documentation for more advanced customization options.

• Q: Is there a limit on the number of options I can add to a command?

  • A: Yes, there is a limit on the number of options you can add to a command. Discord imposes a limit of 25 options per command to avoid overwhelming users with too many choices.
