How do i make spawned enemies have seperate health?

Im making an age of war type game and currently im trying to make my enemy skeletons move until are in the knights FOV then i have the knight making an attack animation and causing a collision. Right now i have a global variable where every time the animation plays it subtracts health until it is below or equal to 0, then it destroys the skeleton. But when it destroys the skeleton it destroys all other skeletons spawned as well as prevents more of them from spawning?

Instead of a global variable you need to use something called an instance variable on the skeleton object itself. This allows each skeleton to have their own health you can subtract, and then when skeleton.health is 0 only that one skeleton will be destroyed.

That worked thank you !
