Thresh is an Object-Oriented Java Library, which takes over the Communication with the League of Legends API. It supports In-Memory caching and uses a (blocking) Rate Limiter. It makes retrieving Summoner Data, Match History, etc. much easier.

Other Projects:

• Spatula for Teamfight Tactics
• Scuttlegeist for Legends of Runeterra
• Fade for Valorant

Thresh can be included like this using Gradle:

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

dependencies {
    ...
    implementation 'com.github.Petersil1998:Core:v1.4'
    implementation 'com.github.Petersil1998:STCommons:v1.4'
    implementation 'com.github.Petersil1998:Thresh-Java:v1.4'
}

or using Maven:

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

<dependency>
    <groupId>com.github.Petersil1998</groupId>
    <artifactId>Core</artifactId>
    <version>v1.4</version>
</dependency>
<dependency>
    <groupId>com.github.Petersil1998</groupId>
    <artifactId>STCommons</artifactId>
    <version>v1.4</version>
</dependency>
<dependency>
    <groupId>com.github.Petersil1998</groupId>
    <artifactId>Thresh-Java</artifactId>
    <version>v1.4</version>
</dependency>

In Order for Thresh to work properly there are a few things you need to set up at the beginning of your application.

public class Example {
    public static void main(String[] args) {
        // First we need to provide our Riot API Key. Ideally the API Key is encrypted
        Settings.setAPIKey(() -> EncryptionUtil.encrypt(System.getenv("API_KEY")));
        // If the provided API Key is encrypted, we need to provide a function to decrypt the API Key
        Settings.setDecryptor(EncryptionUtil::decrypt);
        // We also need to provide a language. The language is used to static Data like Champions, Item, etc.
        Settings.setLanguage(Language.EN_US);
        // If we want to use caching we can enable it in the Settings. Caching is disabled by default
        Settings.useCache(true);
        // We also need to add the Loader for the static LoL Data
        Loader.addLoader(new LoLLoader());
        // Lastly we need to initialize the static Data
        Loader.init();
    }
}

Now Thresh is ready and set up!

• Summoner and Account Data

  public class Example {
      public static void main(String[] args) {
          // Setup code...
          
          Summoner faker = Summoner.getSummonerByName("Faker", LeaguePlatform.KR);
          int summonerLevel = faker.getSummonerLevel();
          // Get the URL for the profile Icon
          String profileIconURL = Util.getProfileIconURL(faker.getProfileIcon());
          // Get Account
          Account account = Account.getAccountByPuuid(faker.getPuuid(), LeagueRegion.ASIA);
          // Get the Tag (e.g. Faker#KR1)
          String tag = account.toString();
      }
  } 

• Champion Mastery

  public class Example { 
      public static void main(String[] args) {
          // Setup code...
         
          Summoner faker = Summoner.getSummonerByName("Faker", LeaguePlatform.KR);
          ChampionMasteries masteries = ChampionMasteries.getChampionMasteriesOfSummoner(faker.getId(), LeaguePlatform.KR);
          // Get Mastery Score
          int masteryScore = masteries.getTotalMasteryPoints();
          // Get Mastery Points on all Champions Combined
          int totalMasteryPoints = masteries.getTotalMasteryPointsCombined();
          // Get a List of all Champion Masteries
          List<ChampionMasteries.Mastery> championMasteries = masteries.getChampionMasteries();
          for(ChampionMasteries.Mastery mastery: championMasteries) {
              // Get the Champion
              Champion champion = mastery.getChampion();
              // Get the Mastery Level on that Champion
              int masteryLevel = mastery.getChampionLevel();
              // Get the Mastery Points on that Champion
              int masteryPoints = mastery.getChampionPoints();
          }
      }
  } 

• Rank and Leagues

  public class Example {
      public static void main(String[] args) {
          // Setup code...
          
          Summoner faker = Summoner.getSummonerByName("Faker", LeaguePlatform.KR);
          // Get Solo/Duo and Flex Rank
          PlayerRanks ranked = LoLRanked.getLoLRanksOfSummoner(faker.getId(), LeaguePlatform.KR);
          RankEntry soloDuo = ranked.getRankSoloDuo();
          int lp = soloDuo.getLeaguePoints();
          RankEntry flex = ranked.getRankFlex5v5();
  
          // Get Challenger Solo Queue Players
          League challengers = LoLRanked.getChallengerLeague(RankedQueue.SOLO_DUO, LeaguePlatform.EUW);
          for(LeagueEntry leagueEntry: challengers.getEntries()) {
              // Get all players and their LP
              Summoner player = Summoner.getSummonerByID(leagueEntry.getSummonerId(), LeaguePlatform.EUW);
              int playerLp = leagueEntry.getLeaguePoints();
          }
  
          // Get a list of Gold 1 Flex Players
          List<RankEntry> firstPage = LoLRanked.getRankEntries(RankedDivision.I, RankedTier.GOLD, RankedQueue.FLEX, LeaguePlatform.NA);
          List<RankEntry> secondPage = LoLRanked.getRankEntries(RankedDivision.I, RankedTier.GOLD, RankedQueue.FLEX, LeaguePlatform.NA, 2);
      }
  } 

• Active Games

  public class Example {
      public static void main(String[] args) {
          // Setup code...
          
          Summoner faker = Summoner.getSummonerByName("Faker", LeaguePlatform.NA);
          // Get Active Game of a given Summoner
          ActiveGame game = ActiveGame.ofSummoner(faker.getId(), LeaguePlatform.NA);
          Map map = game.getMap();
          String gameMode = game.getGameMode();
          int duration = game.getDuration();
          // Get all Players of the blue Side Team
          List<Participant> blueTeam = game.getBlueSideTeam();
          // Get a String, that can be entered in the Windows Commandline to spectate the Game
          String cmd = game.getSpectatorCommandWindows("C:\\");
      } 
  } 

• Match History

  public class Example {
      public static void main(String[] args) {
          // Setup code...
          
          Summoner faker = Summoner.getSummonerByName("Faker", LeaguePlatform.NA);
          // Get the Player's Match History. The Seconds Parameter is a Filter.
          List<MatchDetails> matchHistory = MatchDetails.getMatchHistory(faker.getId(), LeagueRegion.ASIA, Map.of());
          MatchDetails latestGame = matchHistory.get(0);
          int duration = latestGame.getGameDuration();
          // Get Team-based Info like bans, barons killed, turrets killed, etc.
          List<Team> teams = latestGame.getTeams();
          // Get all the Players. Match Participants have A LOT of data like Items bought, Champion played,
          // Summoner Spells used, Damage Dealt, Pings used, etc.
          List<MatchParticipant> participants = latestGame.getParticipants();
      } 
  } 

  The Match History Filter can have the following values:

  Key	Description	Type
  startTime	Unix Timestamp in seconds. Only start Times after June 16th 2021 will have an effect. More	long
  endTime	Unix Timestamp in seconds.	long
  queue	Queue ID. Works mutually inclusive with type. QueueTypes contains all valid queues	int
  type	Type of a Match. Works mutually inclusive with queue	String
  start	The offset of the first Match entry	int
  count	The Amount of Matches entries to return. Has to be between 0 and 100	int

  Note: All values need to be passed as Strings in the filter
