I'm currently in progress updating some engine-code(which does not work, so it is more like creating a engine).

I've decided to swap over to SFML(instead of my own crappy renderer, window manager, and audio), Box2d(since I need physics, but have none), and some small utils I've built myself.

The problem is that each of the project mentioned over use different types for things like Vector2, etc. So to the question;

Is it a good idea to replace box2d and SFML vectors with my own vector class? (Which is one of my better implementations) My idea then was to have a seperate .lib with all my classes that should be shared between all the projects in the solution.
