Hi, my name is Eric Friedman, and I’m a Software Engineer who has been working on League of Legends for 8 years, focusing mainly on gameplay systems. For the last several years, I’ve been working in the Player Immersion and Expression (PIE) initiative, bringing you skins like Elementalist Lux and personalization options like Emotes. If you’re interested in how Elementalist Lux was implemented, check out our previous article. I’m excited to bring you another article about an ultimate skin, Gun Goddess Miss Fortune, and the technology it took to bring her to players.
Hi, I’m Tony Albrecht, an engineer on League. I’m back with some more performance goodness. In the previous article, we tracked a slowdown reported in an LCS game and an issue with Swain that was first reported by players. For this article, we’re stepping back a little further and looking at how we can measure the aggregate performance of League over an entire region, notice a dip, and then narrow down the cause. In this case, we chased a 2ms per frame drop in performance to a single missing ASCII character in our code.
In this article, I’ll be describing how we handle patches across PC and mobile for TFT, and how this relates to quality assurance. Later, I’ll tag in my engineering counterpart, Gavin Jenkins, to give a super techy point of view on patches, and we’ll dive into two use cases that demonstrate different types of patches and how we deploy them.
Hi, I’m Jim ‘Anodoin’ Merrill, and I work on test automation efforts for League of Legends, focused specifically on the in-game experience. I currently serve as the tech captain to the Build Verification System Development (BVS-Dev) team. In large part, our team builds tools for automated testing and helps teams write better tests.
Hi, I'm Doug Lardo, a solutions architect at Riot Games. In this article, I'm going to introduce the concept of Fault Injection Testing, and talk about the Riot Games API and how they implemented it. Then I’ll discuss our testing methods, what we found, and soap box a little bit about high availability design along the way.
Hi there. I’m Bill “LtRandolph” Clark, and I’m the engineering manager for the Champions team on LoL. I’ve worked on several different teams on League over the past years, but one focus has been consistent: I’m obsessed with tech debt. I want to find it, I want to understand it, and where possible, I want to fix it.
