i have a base class which has some base funtions like
virtual void AI();
virtual void Move();
when i inherit from this do i have to include in the .h and .cpp file of the inherited
void AI();
void Move();
some dont have any AI();
is this the only way to do it ?
is there a better way around this ???
virtual funtions??
Hi thedodgeruk.
To inherit from a class you should include its header file.
You generally never include cpp files.
It's not the only way to do it - for example you could do it using composition. Although it's hard to say if it is better or not - it depends on many things.

If some of your subclasses don't need to do anything, you can do one of two things:
- Provide a default implementation in the base class, which can be simply an empty function
- Provide an empty implementation in the subclasses.
I think the OP is asking if he has to redefine the methods in the derived class.
This depends on whether they have a definition in the base class.
"some dont have any AI" : then the derivation meaning "is a" is probably incorrect. What are the names of your classes ?
You should show some code. Does your first question come from a compilation error you get ?
