I have seen many people on the forums say that you should go and re-invent the wheel every time you want to program something. I realize that statement is a fundamental concept of OOP. I also find I learn best when following examples laid out by someone else. So.. Where can I find some good wheels? Specifically, I am looking for code that relates to 2-D movement and animation in VB.NET. Any code that shows good use of reusability would be good. I have looked at the tutorials on MSDN, but the ones I saw don't create vectors, although there was one that used the predefined "Point" structure. Any help?
