    question about static members and functions

    I have a class called cEntity which has some static variables and some static methods

    I then create a new class from cEntity.. cPlayer: public cEntity

    I was hoping that someone could tell me what happens to the static varible and methods when inheritance is used.

    Are the static variables and methods accessable to the derived class or not?

    I'm a bit confused XD

    It depends on the accessibility of the variables and methods. If they're private, no. If they're public or protected, why wouldn't they be?
    My best code is written with the delete key.

    I think that you can access to static variables and methodos even if they are private. no sure but you can access do none static private variables so i think you can access to static private variables, but like i said not sure

    No, you can't. Prelude is right. You can only access public and protected members from the derived class. Whether they are static or not has no effect on accessibility.

    You are right.
    But if mother class is friend of derived class i think you can access private variable and methods but i'm not sure again.. Right?

    Yes. If it's a friend declared class, then it can access private members and functions and otherwise not; use with caution.
