2D vector operations are just as important as the 3D ones and having individual commands for them is very useful for faster vector operations.

Command syntax:

vector1 vectorFromTo2D vector2

vector1: 2D or 3D vector (Z component is ignored)
vector2: 2D or 3D vector (Z component is ignored)

return: Unit 3D vector (vectorMagnitude == 1) with Z=0

This command can, for example, be used to get the vector direction from position A to position B for using with setVectorDir

P.S: I know we can use setDir, but that one is not suitable for per frame codes.
