Testing Vector3

Because the Vector3 class is so complicated (and important!), I want to test its functionality before plugging it into the upcoming Sprite class. On the CD is a project called VectorTest, which is a Win32 Console project that does not need the whole game engine, just the Vector3 class. The Vector3.h and Vector3.cpp files had to be modified a bit to allow the class to compile on its own. (The Advanced2D.h include and namespace lines were commented out.) As a console program, we need only a main function and will use iostream for output. Among other things, the VectorTest program demonstrates how you can manipulate a vector using operators such as +, —, +=, and —=. See Figure 3.3.

Figure 3.3. The VectorTest program tests the features of the Vector3 class.
