    Do I always need to use member functions in a class to access class variables?

    Just tell me the general idea, I need to clarify and understand it without extra details.

    In a class you usually create variables and functions. And tutorials say you should make your class variables private and set/get their values using class member functions. When is it ok to access class variables directly?

    Probably never - but as with all things programming, exceptions to the rule are possible, and may even be preferred.

    Your average 1-liner set/get is going to be implemented very efficiently anyway, so you should do this by default.

    Plus if your set/get ever needs to become something else, the change to the internal implementation only has to be done in one place.
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.

    Ok, thanks. May I ask a few questions about classes? I'm making a game project and kind of confused about access modifiers for classes.

    Just ask away.
    Someone will answer if they feel willing and able.

    I'll think, maybe in another thread.
