[SOLVED]How do I destroy instances of a object with countdow

Hi all!

I want destroy instances of a object the player spawn in game with button. Then every instance have a quantity of energy and every second the system substract 1 of energy. I want destroy the instance when their energy get zero. The problem I found now is that I have created some instances and when one of them get zero energy all instances are destroyed... any idea?

event

for each player object

sub event

player.energy <= 0 destroy player

event

for each player object

sub event

player.energy <= 0 destroy player

Thanks very much lennaert!! now works fine!
