Core/Math API – Rotation using FQuat
Quaternions sound intimidating, but they are extremely easy to use. You may want to review the theoretical math behind them using the following videos:

- Understanding Quaternions by Jim Van Verth – http://gdcvault.com/play/1017653/Math-for-Game-Programmers-Understanding
However, we won't cover the math background here! In fact, you don't need to understand much about the math background quaternions to use them extremely effectively.
Getting ready
Have a project ready and an Actor with an override ::Tick() function that we can enter the C++ code into.
How to do it…
- To construct a quaternion, the best constructor to use is as follows: ...
