For Alan Wake 2, Remedy Entertainment is using a new data-oriented ECS gameplay framework instead of the previous object-oriented one. As a result, we have performance gains such as cache coherency and multithreading out of the box. Also, being implemented using some of the latest C++ features, the new framework changes the way gameplay programmers write their code by providing them some extra convenience and productivity.

We will present how this framework is used for implementing one of the game's features – the Case Board. We will cover how we describe the Case Board objects with components, how we register their systems, and how we interact with other modules (camera, cursor, etc.). Finally, we'll show how the interaction between C++ code and Lua scripts is organized.


A practical example of the ECS framework application in a real project and a demonstration of how a gameplay engineer's mindset is changed while working with a data-oriented approach. Also, this could be an inspiration for engine developers who are working on their own gameplay frameworks.

Intended Audience

Gameplay programmers and engine programmers working on their own gameplay frameworks. To be able to fully enjoy this presentation, intermediate technical expertise is expected.
