vector3 exsample how to use it and stuff youtube too big for me 
Vector3 is a container of 3 floats:
x, y and z.
It’s often used to represent a 3D point/direction.
Vector3 has also some static values:
Vector3.zero;
Vector3.right;
Vector3.left;
Vector3.up;
Vector3.down;
Vector3.forward;
// etc etc etc
which are macros for special Vector3 values (Vector3.up : x = 0, y = 1, z = 0).
PS: you need to ask clear questions, and also go to the manual for this kind of understanding issue.
