Discord bot client based upon Discord.js 

## Installation

Download the latest version from the [releases page](https://gitlab.vylpes.com/Vylpes/vylbot-core/-/releases).

Copy the config template file and fill in the values.

```env
BOT_TOKEN={TOKEN}
BOT_PREFIX=v!

FOLDERS_COMMANDS=commands
FOLDERS_EVENTS=events
```

* **BOT_TOKEN:** Your bot's token, replace {TOKEN} with your bot token
* **BOT_PREFIX** The command prefix
* **FOLDERS_COMMANDS:** The folder which contains your commands
* **FOLDERS_EVENTS** The folder which contains your events 

Make sure that you **DO NOT** put your .env file into VCS!

## Usage

Implement the client using something like:

```ts
// bot.ts

import { CoreClient } from "vylbot-core";

const client = new CoreClient();
client.start();
```

### Writing Commands

The code below will reply to the user with 'PONG' when they type {PREFIX}ping

```ts
// Ping.ts

import { Command, ICommandContext } from "vylbot-core";

export class Ping extends Command {
	constructor() {
		super();
		this._roles = [ "Moderator" ];
		this._category = "General";
	}
	
	public override execute(context: ICommandContext) {
		context.message.reply('PONG');
	}
}
```

* **roles**: An array containing what roles the user needs in order to run the command.
* **category**: The category the role is part of, useful for categorising commands together in a help command.

The `context` parameter contains the following:
* **name**: The command name
* **args**: An array of arguments supplied with the command
* **message**: The Discord Message object for the command message sent

### Writing Events

The code below will log to the console 'Member Joined: {USERNAME}' when a member joins a server the bot is in

```ts
// Moderation.ts

import { Event } from "vylbot-core";
import { GuildMember } from "discord.js";

export class Moderation extends Event {
	public override guildMemberAdd(member: GuildMember) {
		console.log(`Member Joined: ${member.tag}`);
	}
}
```

The following events are supported:
* channelCreate(channel: Channel)
