Discord Rich Presence

This is a fork from the original repo by Lachee.

This fork mainly makes the following changes to work within Collapse Launcher:

The original readme reads as follows:

Release 📦 Codacy Badge Nuget GitHub package.json version

This is a C# implementation of the Discord RPC library which was originally written in C++. This avoids having to use the official C++ and instead provides a managed way of using the Rich Presence within the .NET environment*.

While the official C++ library has been deprecated, this library has continued support and development for all your Rich Presence need, without requiring the Game SDK.

Here are some key features of this library:

Documentation

All the documentation can be found lachee.github.io/discord-rpc-csharp/docs/

Installation

Dependencies:

.NET Project

For projects that target either .NET Core or .NETFX, you can get the package on nuget:

PM> Install-Package DiscordRichPresence

You can also Download or Build your own version of the library if you have more specific requirements.

Unity3D Game Engine

Unity Package is being moved to Lachee/Discord-RPC-Unity. Please check the releases / documentation there.

Usage

The Discord.Example project within the solution contains example code, showing how to use all available features. For Unity Specific examples, check out the example project included. There are 3 important stages of usage, Initialization, Invoking and Deinitialization. It's important you follow all 3 stages to ensure proper behaviour of the library.

Initialization

This stage will setup the connection to Discord and establish the events. Once you have done the initialization you can call SetPresence and other variants as many times as you wish throughout your code. Please note that ideally this should only run once, otherwise conflicts may occur with them trying to access the same Discord client at the same time.

public DiscordRpcClient client;

//Called when your application first starts.
//For example, just before your main loop, on OnEnable for unity.
void Initialize() 
{
	/*
	Create a Discord client
	NOTE: 	If you are using Unity3D, you must use the full constructor and define
			 the pipe connection.
	*/
	client = new DiscordRpcClient("my_client_id");			
	
	//Set the logger
	client.Logger = new ConsoleLogger() { Level = LogLevel.Warning };

	//Subscribe to events
	client.OnReady += (sender, e) =>
	{
		Console.WriteLine("Received Ready from user {0}", e.User.Username);
	};
		
	client.OnPresenceUpdate += (sender, e) =>
	{
		Console.WriteLine("Received Update! {0}", e.Presence);
	};
	
	//Connect to the RPC
	client.Initialize();

	//Set the rich presence
	//Call this as many times as you want and anywhere in your code.
	client.SetPresence(new RichPresence()
	{
		Details = "Example Project",
		State = "csharp example",
		Assets = new Assets()
		{
			LargeImageKey = "image_large",
			LargeImageText = "Lachee's Discord IPC Library",
			SmallImageKey = "image_small"
		}
	});	
}

Invoking

Invoking is optional. Use this when thread safety is paramount.

The client will store messages from the pipe and won't invoke them until you call Invoke() or DequeueMessages(). It does this because the pipe is working on another thread, and manually invoking ensures proper thread safety and order of operations (especially important in Unity3D applications).

In order to enable this method of event calling, you need to set it in the constructor of the DiscordRpcClient under autoEvents.

//The main loop of your application, or some sort of timer. Literally the Update function in Unity3D
void Update() 
{
	//Invoke all the events, such as OnPresenceUpdate
	client.Invoke();
};

Here is an example on how a Timer could be used to invoke the events for a WinForm

var timer = new System.Timers.Timer(150);
timer.Elapsed += (sender, args) => { client.Invoke(); };
timer.Start();

Deinitialization

It's important that you dispose your client before your application terminates. This will stop the threads, abort the pipe reads, and tell Discord to clear the presence. Failure to do so may result in a memory leak!

//Called when your application terminates.
//For example, just after your main loop, on OnDisable for unity.
void Deinitialize() 
{
	client.Dispose();
}

Building

Release 📦 Documentation 📚

DiscordRPC Library

dotnet build -c Release

Unity3D

If you wish to have barebones Unity3D implementation, you need to build the DiscordRPC.dll, the Unity Named Pipes Library and the UnityNamedPipe.cs. Put these in your own Unity Project and the .dlls in a folder called Plugins.

UWP / .NET MAUI / WIN UI 3

For now, the library doesn't work on UWP applications until we find the issue and fix it.

In order to make this library work with the WIN UI 3 related applications such as .NET MAUI, you need to define runFullTrust Capability inside Package.appxmanifest.

Here is an example of how to add runFullTrust to your WIN UI 3 application:

Package.appxmanifest:

<?xml version="1.0" encoding="utf-8"?>

<Package
  xmlns="http://schemas.microsoft.com/appx/manifest/foundation/windows10"
  xmlns:uap="http://schemas.microsoft.com/appx/manifest/uap/windows10"
  xmlns:rescap="http://schemas.microsoft.com/appx/manifest/foundation/windows10/restrictedcapabilities"
  IgnorableNamespaces="uap rescap">
  ...
    <Capabilities>
	    <rescap:Capability Name="runFullTrust" />
    </Capabilities>
</Package>

If you use .NET MAUI or WIN UI 3 template for C#, it automatically puts runFullTrust capability.
