This fork fixes an issue with Thunderstorm010's fork where an empty button array is passed in if no buttons are present, resulting in no rich presence being shown. (TLDR: You are no longer required to have buttons added in order for your rich presence to show.)

Connect locally to the Discord client using IPC for a subset of RPC features like Rich Presence and Activity Join/Spectate

• Setting Rich Presence
• Listen for Join, Spectate, and Join-Request events
• Detect and specify priority for client build (Stable, PTB, Canary)
• 100% Java

First you'll need to add this project as a dependency. If you're using maven:

  <dependency>
    <groupId>com.github.hapily04</groupId>
    <artifactId>DiscordIPC</artifactId>
    <version>3389be879d</version>
  </dependency>

  <repository>
    <id>jitpack.io</id>
    <url>https://jitpack.io</url>
  </repository>

With gradle:

dependencies {
  implementation 'com.github.hapily04:DiscordIPC:3389be879d'
}

repositories {
  ...
  maven { url 'https://jitpack.io' }
}

Quick example, assuming you already have a GUI application

IPCClient client = new IPCClient(345229890980937739L);
client.setListener(new IPCListener(){
    @Override
    public void onReady(IPCClient client)
    {
        RichPresence.Builder builder = new RichPresence.Builder();
        builder.setState("West of House")
            .setDetails("Frustration level: Over 9000")
            .setStartTimestamp(OffsetDateTime.now())
            .setLargeImage("canary-large", "Discord Canary")
            .setSmallImage("ptb-small", "Discord PTB")
            .setParty("party1234", 1, 6)
            .setMatchSecret("xyzzy")
            .setJoinSecret("join")
            .setSpectateSecret("look");
        client.sendRichPresence(builder.build());
    }
});
client.connect();
