Ok so when i load up my game what happens is when i shoot an enemy, all of the copies die.
What i did was (so that the enemies have health) make a global value for Enemy 1 that can only be changed by enemy 1 being shot, like this
Collision with (Bullet) And (Enemy 1)=
Add 1 to Global value 1 (Enemy 1's Health)+ Destroy Bullet
Then what i did was made it if its shot twice it would die and reset its health after death for the next copy.
Enemy 1 Health is bigger than 2=
Set Global Value 1 to 0 + Create Explosion + add 50 to score + destroy Enemy 1
After i shoot them they all die but not only that, the next wave of the same enemies have no health at all and never die
I would love for someone to help me out as its pretty game breaking
