I have added a virtual function to AActor, why can't i compile?

[anonymous_user_870870e91 (anonymous_user_870870e9)]

It is not necessary to edit that class. And I would advise strongly against doing it.

You can accomplish what you want by making a new base class that inherits from actor
and then making classes that are children of your new base class

This is definitely the way to go.

But to refer to your errors, you’ve got linker errors because you didn’t provide an implementation. You can write in the header file e.g. virtual void Hit() {} to provide a empty one. But like Colorado said, just don’t edit the Actor class.

Create a new base class

Actor
   |
   v Unit (your class with the hit function
   |
   v Your classes which should inherit the hit function
