i am lazy so here is how i would do it with out this codey stuff confuseing me. create an acitive object and copy it a few times and put the pecies in the health bar. also make another one that is invisible at the start of frame and make movment one of that object static and movment 2 to me path movment. make it move to the first part of the health bar. then make another tape movment and make it go backwards but little bit before so that when it is avite again it will touch the second pice. make movment two active when you get hit and when path gets to the end switch it back to movment one and when the invissible object toches a part of the health bar set it to destroy that pice. hope that helped.
