Help Needed To understand UE4 C++ programming

I am completely new to ue4 with little knowledge about c++ oop. Upon reading the c++ programming codes in ue4 doc. I could not understand many keywords like deltatime, etc. So what do you prefer to learn/do to understand them better.

DeltaTime isn’t a C++ keyword, it’s an argument name on the Tick method that passes in the time elapsed since the last tick.

I would recommend running through the basic tutorials on LearnCPP.com or similar so you get an understanding of the basic C++ syntax. Once you’ve got that, using C++ in UE isn’t really more complicated than any other scripting language.

Thanks for helping ! I ll be surely using your methods
