Thanks so much to you guys. I have to say sorry that I did not think about this kind of stuff when I ask questions, but certainly I should.
I think I would manage to avoid my subjects to run out of rockets by give them some rules. I would reduce my task down to 35 targets in the mission, 50 rockets would be just about ok if ppl don't abuse their weapon.
Good news to me that most of problems have been solved, and my mission have been tested and modified. It looks much better now.
My headache in another mission is about the question I have posted before, about how to output flying status data to a file on local harddisk. After a while I could not find any help, probably I am about giving up that idea now.
I am really grateful that you guys keep helping me out of my problems.
