Answer 2

I don't know much about c# but I know about unity: if you are referring to Vector3 or Vector2, I might help you. If you aren't I'm sorry but I can't help you
Vector3 in Unity:
Vector3 is a class with only one costructor that is Vector3(int x, int y, int z) that return a Vector with that x,y,z.
Vector3 are 3 number in a class and are used for both position and eulerAngles
(a way to show rotation, like if you change in the inspector, you are changing an euler angle). Vector3 also a magnitude, that is their lengths (used for force stuff)
