Hello,
I was able to figure it out. I was using Global Variables for the HP before witch made all Enemies get hurt at once, but than I switched over to Instance Variables and now it works where it will subtracked HP only from the Enemy that is getting hit within a Families group.
Its nice because now the only thing I have to do is name the enemies (Enemy1, Enemy2), and so on without having to add the same code over and over again for each enemy.
Thank you :)
