How can I find angle between 2 vectors (Points in world coordinate)?
Is there any build in function that can allow me to find the Rotator between 2 points(vectors) in the world coordinate?
I tried searching a few maths libraries but couldn't find any. So is there a function that can do what I want or I need to manually write the function?
Basically, to find vector between two other vectors you have to subtract one from another.
