Zeus Modification Help

[Pmike2004]

Hi,
Thanks for looking at this. I'm not so much looking for the answer (I'll never learn that way) but what I am looking for is possibly an idea or thought provoking statement that may help me move toward the right direction.

I am doing "Zeus Modification" in chapter 5. I have no idea how to make the object become null after hit by a lightning bolt. I actually have no idea where to even start with this task.

Through trial and error I'm sure I can make him fall to the ground, but I was hoping that I could get some sort of direction from someone here. I will attach my file (zipped) for you to look at if you want, but it is exactly how the book portrays it.

Anyway, thank you very much for whatever help you are able to provide!
