What is the C++ equivalent of the Get Direction Vector node in blueprints?

Alright, apparently it’s just:

direction = target - currentLocation

Check out some vector math, the result of subtracting two points in space is a vector between them.

From Game Engine Architecture:

direction + direction = direction
direction – direction = direction
point + direction = point
point – point = direction
point + point = nonsense (don’t do it!)

It’s not.
The GetDirectionVector outputs a normalized vector, which has the difference with the vector obtained by subtraction that it’s length is equal to 1.

You can easily find the normalized vector by doing the following math:

This will also work too.
