Coroutines are a revolutionary language feature that can express complex gameplay logic through direct, clear functions. C# and Lua programmers have had access to coroutines for over a decade, but most C++ developers don't realize that coroutines were recently added to C++! Coroutines are now available and production-ready on all major game platforms using the C++14 language standard.

Elliott, one of the programmers behind The Pathless, shares how he wrote the entirety of The Pathless' gameplay code using C++ coroutines, and demonstrates how easily they can be integrated into existing game projects. Elliott also introduces Giant Squid's MIT-licensed library to jump-start the integration process. Discover how easy it is to unlock this futuristic new programming paradigm with a minimum of risk and effort.


Elliott explains what coroutines are, motivates their use in game programming, shows how they can be implemented in C++14 today, and demonstrates writing gameplay logic using C++ coroutines. In the process, he reveals how everyday game programmers can start implementing C++ gameplay coroutines in their own games.

Intended Audience

Gameplay programmers of all experience levels will benefit from attending this talk. Knowledge of C++ is recommended (not required), including familiarity with templates and lambda functions. Engine programmers will also see how coroutines can be integrated into game frameworks and apply coroutines to non-gameplay systems.
