Repository with examples on how to implement TwitchLib within Unity. This project is a WIP and is still being updated.
A repository which contains a Unity project with a few example implementations and Unity Unit Tests. The actual TwitchLib project can be found here
Below are basic examples of how to utilize TwitchLib.Unity libraries including Api, Chat Client and PubSub
// If type or namespace TwitchLib could not be found. Make sure you add the latest TwitchLib.Unity.dll to your project folder
// Download it here: https://github.com/TwitchLib/TwitchLib.Unity/releases
// Or download the repository at https://github.com/TwitchLib/TwitchLib.Unity, build it, and copy the TwitchLib.Unity.dll from the output directory
