Question
I’ve been created a Parent Scene as EnemyBase and after that I created Inherited Scene from that as Child that is Enemy. Now, I am creating instances of child on the Level Scene but all child has the same behavior. When I do hit in one enemy the others enemies has receiving hit too. I don’t know why it is happens and how could I fix it.
