Github Actions NuGet Stable NuGet Pre Release API Reference

C# Library for the Riot Games API

Camille's goals are speed, reliability, and maintainability. Camille handles rate limits and large requests with ease. Data classes are automatically generated from the Riot API Reference (Swagger).

Features

  • Fast, asynchronous, thread-safe.
  • Automatically retries failed requests.
  • Automatic up-to-date nightlies, reflecting Riot API changes within 24 hours.
  • Multi-targeted: .NET Standard 1.1+, .NET Framework 4.5+, .NET Core 2.0, .NET Standard 2.1+, .NET Core 3.0+.
  • Highly-configurable.
  • New TFT API Supported!

Installation

Install via NuGet (MingweiSamuel.Camille).

Usage

All API interactions are done using a RiotApi instance. RiotApi.NewInstance takes either just an API key (for default settings) or a IRiotApiConfig instance (for custom settings).

var riotApi = RiotApi.NewInstance("RGAPI-12345678-abcd-1234-abcd-123456abcdef");
// OR
var riotApi = RiotApi.NewInstance(
    new RiotApiConfig.Builder("RGAPI-12345678-abcd-1234-abcd-123456abcdef")
    {
        MaxConcurrentRequests = 200,
        Retries = 10,
        // ...
    }.Build()
);

You can find all configuration options here.

API methods are divided up into respective endpoints, corresponding to the left bar of the API reference.

Example

// Get summoners by name synchronously. (using async is faster).
var summoners = new[]
{
    riotApi.SummonerV4.GetBySummonerName(Region.NA, "jAnna kendrick"),
    riotApi.SummonerV4.GetBySummonerName(Region.NA, "lug nuts k")
};

foreach (var summoner in summoners)
{
    Console.WriteLine($"{summoner.Name}'s Top 10 Champs:");

    var masteries =
        riotApi.ChampionMasteryV4.GetAllChampionMasteries(Region.NA, summoner.Id);

    for (var i = 0; i < 10; i++)
    {
        var mastery = masteries[i];
        // Get champion for this mastery.
        var champ = (Champion) mastery.ChampionId;
        // print i, champ id, champ mastery points, and champ level
        Console.WriteLine("{0,3}) {1,-16} {2,10:N0} ({3})", i + 1, champ.Name(),
            mastery.ChampionPoints, mastery.ChampionLevel);
    }
    Console.WriteLine();
}

This example takes advantage of C#'s async/await tasks to fetch 10 matches all at once.

var summonerNameQuery = "lugnutsk";

// Get summoners data (blocking).
var summonerData = await riotApi.SummonerV4.GetBySummonerNameAsync(Region.NA, summonerNameQuery);
if (null == summonerData)
{
   // If a summoner is not found, the response will be null.
   Console.WriteLine($"Summoner '{summonerNameQuery}' not found.");
   return;
}

Console.WriteLine($"Match history for {summonerData.Name}:");

// Get 10 most recent matches (blocking).
// Queue ID 420 is RANKED_SOLO_5v5 (TODO)
var matchlist = await riotApi.MatchV4.GetMatchlistAsync(
   Region.NA, summonerData.AccountId, queue: new[] { 420 }, endIndex: 10);
// Get match results (done asynchronously -> not blocking -> fast).
var matchDataTasks = matchlist.Matches.Select(
       matchMetadata => riotApi.MatchV4.GetMatchAsync(Region.NA, matchMetadata.GameId)
   ).ToArray();
// Wait for all task requests to complete asynchronously.
var matchDatas = await Task.WhenAll(matchDataTasks);

for (var i = 0; i < matchDatas.Count(); i++)
{
   var matchData = matchDatas[i];
   // Get this summoner's participant ID info.
   var participantIdData = matchData.ParticipantIdentities
       .First(pi => summonerData.Id.Equals(pi.Player.SummonerId));
   // Find the corresponding participant.
   var participant = matchData.Participants
       .First(p => p.ParticipantId == participantIdData.ParticipantId);

   var win = participant.Stats.Win;
   var champ = (Champion) participant.ChampionId;
   var k = participant.Stats.Kills;
   var d = participant.Stats.Deaths;
   var a = participant.Stats.Assists;
   var kda = (k + a) / (float) d;

   // Print #, win/loss, champion.
   Console.WriteLine("{0,3}) {1,-4} ({2})", i + 1, win ? "Win" : "Loss", champ.Name());
   // Print champion, K/D/A
   Console.WriteLine("     K/D/A {0}/{1}/{2} ({3:0.00})", k, d, a, kda);
}

API Reference

Automatically generated API Reference

Source Code

Source code is located in the src/ directory, corresponding to the MingweiSamuel.Camille namespace.

RiotApi.cs is the main point of entry for interfacing with Camille, however this source file is only a partial class. The remainder of the class is automatically generated and not commited to the master branch, but is viewable as described below in the "Generated Classes" section.

Files in the src/util directory/MingweiSamuel.Camille.Util namespace are internal classes used for sending requests and handling rate limits.

Generated Classes

The majority of the code in Camille is automatically generated. The generated sources are not commited to the master branch, but are available in the gh-pages branch in the _gen/ directory.

GeneratedClasses.cs contains all endpoints, and therefore endpoint methods, as well as all the data transfer objects corresponding to the JSON returned by the Riot API.

Champion.cs is an enum for working with champion IDs.

RiotApiConfig.cs is the configuration builder code for creating RiotApi instnaces with custom settings.

The actual code for generating these classes is in the src/gen folder. The C#-generating code is in *.cs.dt files and is written in NodeJS, using doT.js templates.
