(iOS) Run Video Chat within your Unity application 📱🎮

When playing games with your friends, the real fun comes when you can trash-talk and gloat on how good you are! Whether you are playing a first-person shooter or playing a game of poker, you want to be able to communicate with your team or see the competitors’ reactions to see if they are bluffing. More mobile games are adding real-time communication within their app to increase user stickiness and user engagement.

The Agora Video SDK for Unity enables you to add in-game real-time communications to increase interactivity between players with minimum impact on the gameplay.

A sample app is included in the Unity Asset and demonstrates the basic Agora SDK features:

  • Join a Channel
  • Leave a Channel
  • Video Chat with multiple participants

This blog post will enable you to run the sample app on an iOS device within a few minutes.
