I'm currently in the process of making a top-down shooter for my programming class, and one idea I had, but don't exactly know how to implement is image rotation in order to spin the object continuously. What I have are spaceships, and right now all they do is face one static direction. All I want is to have them non-stop spinning at a rate that people can see (not so fast that it looks like a blur). I've seen some code about rotating by a certain degree, etc; but no constant rotations. I'm not too sure how to go about this, but any help would be appreciated greatly.
Also, I'm using C# and Visual Studio 2010.
