                if((b > -90) || (b <= 90) && (p > 0) && (q > 0)){

                    Link->X += suckx;

                if((b > -90) || (b <= 90) && (p < 0) && (q < 0)){

                }
                if((b == 0) && (q < 0)){
                    Link->Y += sucky;
                }
                if((b >= -90) || (b <= 90) && (p > 0) && (q < 0)){
                        (Link->X - suckx) & (Link->Y + sucky);

        }
    }
}

So, I'm wondering how I could fix the dead zones between 46 to 89 and -46 to -89 degrees. I've thought of an inverse x and y, but that doesn't work...

EDIT:

b = Pow(Tan(q / p), -1);

Found the culprit. It's not the equivalent of arctan. I need to rewrite this to include all angles between 0 and 90, or 0 and -90.
EDIT: Never mind, I fixed the problem by changing all my OR statements into AND statements.
