Java Wrapper of the Discord-RPC Library for Discord Rich Presence.

Ever wanted to use the Discord Rich Presence API in a Java Application, but then realized that the native version is C++ only? Well, worry no more, because Vatuu's Discord RPC is here. A complete wrapper of all functions the native Dynamic Library contains.

Features

Set advanced pieces of information about your game in the players' profile, when they use your Application, from text to images, timers and even giving the option of joining/spectating a game!

The so-called Rich Presence contains the following fields for you to fill in:

• State: The general state the current play-session is in (Waiting, Playing, Watching some leaderboards, etc).
• Details: Details to the current play-session, like the location, or current score.
• Timestamps: Show how long the current game-session will go, or how long the player is already playing, up to you.
• Images: One big cubic, and one smaller round images with a custom tooltip text, to show some more details.
• Parties: Show the current size of parties or lobbies to indicate if the player is forever alone or not.
• Match/Join/Spectate: Some super secret Strings that are needed for joining and spectating a game. More to that below.
• Instance Int: If it's a game instance or not, as simple as that.

How to use?

Using this wrapper is as simple as it can be, with barely any difference of the "original" API.

Step 0

Download one of the releases or download the sources to build your own release. Then, simply add and include it in your project.

Currently supported OS include Windows x86, Windows x64 and Unix x64. OSX and macOS support is currently broken, although we're working hard on getting it to work again.

Step 1

Initialize the Discord RPC when your Application starts up. The Library is mostly static, so there is no need to create an Instance. The DiscordRPC.discordInitialize(); method takes 3 arguments to start.

• Client ID is the ID of your Discord Application.
• Handler is an instance of a DiscordEventHandler-Object. Callbacks to HandlerClasses are registered in there.
• AutoRegisterdoes not really matter right now and is always true.
• If your application is a Steam Application, the Initialize Methods takes another String of your Steam App ID.

The Event Handler contains instances of the classes that handle Callbacks of the DiscordRPC. These classes have to implement the appropriate Interface for the Callback. The Callback-Interfaces are the following:

• DisconnectedCallback
• ErroredCallback
• JoinGameCallback
• JoinRequestCallback
• ReadyCallback
• SpectateGameCallback

To register a Callback, simply follow the following code:

              public              static              class              ReadyEvent              implements              ReadyCallback              {              public              void              apply() {              System              .out.println(                "Discord's ready!"              );   } }              public              class              MainClass              {              public              void              startup() {              DiscordEventHandlers              handlers              =              new              DiscordEventHandlers.Builder().setReadyEventHandler((user)              -              >              {              System              .out.println(                "Welcome                "                            +              user.username              +                              "#"                            +              user.discriminator              +                              "!"              );     }).build();   } }

All Callbacks are optional. You only need to register Classes that implement the Callbacks you need, or if you don't need any, simply pass an empty DiscordEventHandler Object.

To summarize:

              public              void              startup() {              DiscordEventHandlers              handlers              =              new              DiscordEventHandlers.Builder().setReadyEventHandler((user)              -              >              {              System              .out.println(                "Welcome                "                            +              user.username              +                              "#"                            +              user.discriminator              +                              "!"              );   }).build();              DiscordRPC              .discordInitialize(                "1234567890"              , handlers,              true); }

This would result in the message "Welcome User#1234!" being printed out in the console after the connection to Discord has been established, and fitted with the users username and discriminator.

Step 2

To allow callbacks to be fired, you have to periodically call the method DiscordRPC.discordRunCallbacks();. Otherwise, no callbacks will be passed to the application.

Congratulations, your Application is ready to utilize the Rich Presence.

Updating the Presence

To update the Rich Presence of a player, a DiscordRichPresence Object is required. There are created in the same way as the EventHandler is created, by using a Builder:

              public              void              createNewPresence() {              DiscordRichPresence              rich              =              new              DiscordRichPresence.Builder(                "This is the current state."              ).setDetails(                "These are some details."              ).build(); }

After the Object has been created, it simply has to be passed to the DiscordRPC with the methods DiscordRPC.discordUpdatePresence(DiscordRichPresence);

              public              void              createNewPresence() {              DiscordRichPresence              rich              =              new              DiscordRichPresence.Builder(                "This is the current state."              ).setDetails(                "These are some details."              ).build();              DiscordRPC              .discordUpdatePresence(rich); }

After calling that method, the presence of the player will have updated, according to the information passed. Just like the EventHandler before, all fields are optional and can be left empty if one desires so. Just keep in mind that a Match- Join- and Spectate Secret are needed when utilizing the Join and Spectate features.

More information regarding the fields of the Rich Presence and the correct usage of them can be found HERE.

Shutting down the RPC

To allow the IOStream utilized by the RPC to close properly, the method DiscordRPC.discordShutdown(); should always be called on exit of your application, otherwise issues might occure.

Joining and Spectating

The method DiscordRPC.discordRespond(String userId, DiscordReply reply); handles the reply on a JoinRequest by a player. When a player requests to join a game, the JoinRequestCallback is called, which should be used to process the request. That request contains the Username, UserID and the avatar of that user transformed into a SHA-1 hash.

Important Note: To let a application use the Spectate Feature, the application has to be greenlit by the Discord Developers. Otherwise, only certain users added to the Application will be able to use these features.

~~ More will be added soon ~~

The Example Application

Contained in this repository is a .JAR file called RPCTest.jar. This simple command line application can be used to test the Rich Presence for yourself! Simply add the Application named "RPCTest" to your Discord Games, and it will be recognized. Since Discord only detects games that have an active window, I discourage you from closing the small window called "Derp" that will pop up as soon as you start the RPCTest.

The RPCTest has only two commands:

• test will increase the "score" value in the details of your presence.
• shutdown is self-explanatory.
