My question is simple, i already have a script wich is like the one used in disaster game(waittime, gametime and repeat...), but what i want to do now is after the ENEMY(an AI) health=0 the round ends and players get awarded by the damage dealed to ENEMY
how do i know the damage dealed by each player?

@chess123mate hmm... a new value inside each player that stores the damage dealed. can work too?
Of course - so long as either the weapons increase those values directly or else generate tags that you can monitor and then increase the "damage dealt" values through another script.
