What do you want to detect collisions of? If it is simply two spheres, 
use something like
#if(vlength(CenterA - CenterB)<(RadiusA + RadiusB))
   // spheres are colliding
#else
   // spheres are not colliding
#end

The math is pretty simple for many other objects. I don't know of any 
macros for this.
