do i have to create my own vectors in gdi(or directX) graphics programming?

[fguihen]

im creating a simple represntation of a person, which is only a filled in circle in gdi. i want to assign speed and direction to it. do i have to create a class, or struct called vector, or is there a datatype already there that takes in a speed and an angle ?

If you are using DirectX then you get Vector2, Vector3 and Vector4 (for 2d, 3d and 4d vectors).

what about if im just using GID to start off with ? do i create my own vector class?

In that case yes.
