The Architecture of the League Client Update

Greetings! My name is Andrew McVeigh, and I'm a software architect at Riot.

We're in the latter stages of re-engineering the League of Legends client. We're calling this the League client update. In this post, I’ll outline the software architecture of this update and provide some background to the choices we made by pointing out some of the limitations of the current (original) client. The journey to our final architecture has been technically fascinating, and I’m excited to be able to share it with you!

A Story of Fog and War

In late 2013, Riot’s map team started to work full-tilt on updating Summoner’s Rift, the flagship map for League of Legends. It was an enormous task: not only did the team need to upgrade the map’s look and feel while preserving the bits that players loved, they needed to do it without increasing the minimum required hardware spec.

Content Efficiency: Game Data Server

Hey, everyone! I’m Bill “LtRandolph” Clark, a League of Legends gameplay engineer. Many Rioters in engineering focus on the delivery of awesome content directly to players—a couple of my recent favorite examples include the newest champion, Jhin, and the support item reworks. My team, on the other hand, works to make that process faster and easier.

We have a simple goal: to allow Rioters on gameplay projects to create twice as much content for any given LoL patch. That’s easy to say, but it’s a challenging task.
