[QUESTION]how can i detect with vb when alien die

[-popcorn-]

any one have an visual basic script that can detect when a battleray is dead?(i mean if i am killing it, when exactly it explode, start counting), is for my battleray tool (bellow in my signature is 2nd program).

my program is basicly a timer, but u need to click a button when battleray died, the idea is make program detects byself when it dies and start counting, anyone have any idea about how to make an script?
