Looking for Ue4 C++ command equivalents (Unity)

Development Programming & Scripting

I’ve searched pretty long and didn’t found the equivalent these two commands, maybe someone of you knows the ue4 C++ version:

Quaternion.identity

Quaternion.FromToRotation()

Quatification type in UE4 is FQuat and you can find all you need in API reference:

The Identity is a static const at the end of API refrence so you get it like this:

FQuat::Identity

Getting it from Rotation (which in UE4 is FRotator) you can either do that by direcly constructing FQuat from FRotator:

FQuat(FRotator(Pitch,Yaw,Roll))

or from convert directly from function in rotator:

FRotator(P,Y,R).Quaternion()

Explore recommand APIre refrence, here basic geometric types:

All basic math operations contained n FMath it has operations for C++ primitives like int32 and float, all of them are static functions do you call them starting with FMath:: :
