Async loading screen. Oct 28, 2024 · The function template std::async runs the function f asynchronously (potentially in a separate thread which might be a part of a thread pool) and returns a std::future that will eventually hold the result of that function call. If one thread writes to an atomic object while another thread reads from it, the behavior is well-defined (see memory model for details on data races). Sample project:ht In this quick video, I will take you through how to asynchronously load a soft object pointer, with the example using a Primary Data Asset. Coroutines are stackless: they suspend execution by returning to the caller, and the data that is required to resume execution is stored separately from the stack. The creator of the asynchronous operation can then use a variety of methods to query, wait for, or extract a value from the std::future.
