Is it possible to change a child class into a parent class?

I have two characters in my game and the second one is a child class to the first character.
Is it possible to change the child class it into a parent class?

You mean changing class of actor in runtime? No you can’t do it, you need to spawn new and destroy old actor

Not at runtime, but otherwise yes. You can re-parent a blueprint. Re-parent the “parent” blueprint into “child” blueprint and it will swap the relationship around. You can also create other blueprints of child directly and it will automatically become their parent.
