hi.
Ok,when i want to detect collision between sprites i use bounding boxes
rectangle following my sprite.
In my case, that is:

i have a ship(i make a space invaders for training me to C ...)like
this(approximatively!!):

                i
               iiii
          i   iiiiiii   i                <----This is the ship(fabulous
isn't it?)
          iiiiiiiiiiiiiii
            iii     iii


i have a super-laser-bullet like this:

   the laser--->       0                 <----(i can believe my eyes!
this laser-bullet is so terrific)


How can i  make this collision operations between this two objects?:





                i
               iiii   0
          i   iiiiiii   i   ----->here no collision
          iiiiiiiiiiiiiii
            iii     iii


                 i
               iiii
          i   iiiii0   i   ----->here, there is collision
          iiiiiiiiiiiiiii
            iii     iii

Like you can see on my terrible ASCII graphics, the bounding box method
don't works, how can i do?
