Creating a custom extension

The bot is almost fully modular and allows you to make a custom extension in the blink of an eye.

To create an extension, you'll need two things:

• The extensions source (.dll)
• The sql command, to add the extensions trigger to the database (.sql)

---

Let's start with the source code. You will need to import Discord C# to create an extension. It can be imported via NuGet.

//Importing standard C# libraries
using System;
//Importing Discord C# functions
using Discord.WebSocket;

//Your class
public class HelloWorld
{
	//The message, that was sent from the user
	private SocketMessage Msg;

	//You'll ALWAYS need a constructor, that accepts a SocketMessage, to create an extension
	public HelloWorld(SocketMessage message)
	{
		Msg = message;
	}

	//This is the function, that will be triggered, when the user inputs the according command into Discord
	//These functions MUST return a String.
	public String SayHello()
	{
		//In my case this would return "Hello @ADarkHero!"
		return "Hello " + "<@" + Msg.Author.Id + ">!";
	}
}

Quite simple, isn't it? The most important things are the constructor and the method, that has to return a String. Everything else is up to you.

When your code is done, you can build it as .dll. Next you'll have to put the .dll in the /ext directory of the bot. The bot automatically loads all dlls in that directory. Files in other directories will be ignored. Files that are not .dll will also be ignored.

---

The next step is the sql part. This tells your bot, when your command should trigger.

INSERT INTO commands 
(
	CommandName, -- The command that the user has to input to trigger a function; Input the CommandName without the DicordChar (by default !)
	CommandComment, -- A comment, that will be displayed, in the command overview
	CommandType, -- The type of the command. 0 => Simple; 100 => Regex; 101 => Complex
	CommandRegex, -- You'll need to fill this, if a regex should trigger your function
	CommandObject, -- Name of the object, that should be generated, when the Discord-user inputs a command
	CommandFunction, -- Name of the function, that should be triggered, when the Discord-user inputs a command (without braces)
	CommandAlias, -- If your function should be triggered by multiple commands, you can set an alias, to not show all of the commands in the command overview
	CommandRights -- What rights are needed to execute the command? null => No rights; 1 => Only server admins can use it.
)
VALUES
(
	"HelloWorld",
	"Displays a Hello World message.",
	101,
	null,
	"HelloWorld",
	"SayHello",
	null,
	null
)

You'll need to execute this sql code in the database.db SQLite database.

You're done now! Your custom extension is ready to rock!
