Looks like 5 test between 2 positions, both in time and space. You take 
start position and end position, then you interpolate 5 steps to see if 
there is any colision in that interval. I think that it's possible to 
find that in one step, but I can't replace the mathematics to do that. I 
think that you need some integral or diferential function.
