The second one (using Delegates) is pretty much done the way, I've already posted. However If you wanted to use function pointers, then you can use std::bind and std:function from the #include <functional> library, like this: How does the main thread tell the asynchronous computation what to do when it completes? How does the asynchronous computation return its result: it is now decoupled from the thread that called it and it cannot return any value . A continuation solves both problems: It is a function that must be invoked when the asynchronous computation completes. missing persons hot springs arkansas UMG was introduced as an experimental feature in Unreal Engine 4.
