random player pick question

im making a map that involvs random player pick like in all of the murders that i know (mansion, graveyard) that pick a random player to be the killer. how do u make that trigger?

wow i thought this was easy at first.. just store a rand # to a variable and use it as a player index.

Oh wait this will work.. :
set variable(int) = random integer between 1 and (max # of players)
if player slot status of Player[variable(int)] is not equal to is playing then run this trigger else do nothing

BAM!

ok kool thx
