How to program LaunchCharacter in C++?

Hi im trying to translate my BP code to C++ ,im almost done StaticMesh and Collision Box are create, only the knockback function is remaining but i dont find any tutorial to learn how to do the “LaunchCharacter” in C++


The screenshot is too small, can you upload the full-sized one?

About the LaunchCharacter – not sure what exactly you mean (since I can’t read the screenshot), though there is the same method available in C++.
