    I have two locations, X1/Y1/Z1, and X2/Y2/Z2. How do I go from the first point to the second in an imcrement of 0.5? Do I have to do it somehow using vectors?

    yes, you have V1 and V2 position vectors, and want V3 of length 0.5 parallell to V2-V1
    V3 is then 0.5*(V2-V1) / |V2-V1|

    differences of components for vector difference and multiply components with factor for vector product.
    |V*| is the magnitude of a vector and is evaluated with
    sqr(X*X+Y*Y+Z*Z)
    Use
    writing software in C++ is like driving rivets into steel beam with a toothpick.
    writing haskell makes your life easier:
    reverse (p (6*9)) where p x|x==0=""|True=chr (48+z): p y where (y,z)=divMod x 13
