today, instead of pixels, I am gonna talk about another thing in a game engine – Jobs. Specifically, based on C++ coroutine which we shipped in C++ 20, without standard library support. I because the contents cache off the value. And here you can see we have this single consumer counter event, implemented based on the Operating system API. In this case, I use WaitForSingleObject on windows, you can also use
