Example 1 with MessageHandler

use of com.sedmelluq.discord.lavaplayer.node.message.MessageHandler in project lavaplayer by sedmelluq.

the class PlayingTrackManager method handleTrackStart.

@MessageHandler
private void handleTrackStart(TrackStartRequestMessage message, MessageOutput output) {
    InternalAudioTrack audioTrack = (InternalAudioTrack) manager.decodeTrackDetails(message.trackInfo, message.encodedTrack);
    String failureReason = null;
    if (audioTrack != null) {
        if (message.position != 0) {
            audioTrack.setPosition(message.position);
        }
        PlayingTrack playingTrack = new PlayingTrack(message.executorId, message.volume, audioTrack);
        PlayingTrack existingTrack = tracks.putIfAbsent(message.executorId, playingTrack);
        if (existingTrack == null) {
            log.info("Track start request for {} (context {}, position {})", message.trackInfo.identifier, message.executorId, message.position);
            manager.executeTrack(playingTrack, audioTrack, message.configuration, playingTrack.volume);
            statisticsManager.increaseTrackCount();

}

Example 2 with MessageHandler

use of com.sedmelluq.discord.lavaplayer.node.message.MessageHandler in project lavaplayer by sedmelluq.
