C++ is a clusterfuck. It's a hybridal language, mixing paradigmates, syntax and extremely low- level features with high- level ones. The hate towards C++ is completely justified. Any talk about 'C++ purism' makes me smile. It's an artificial approach and depends heavily on the politics of a project.
Measuring a profficiency in programming language, by the ability to apply an ideology instead of solving problems in the most efficient way meeting the requirements, is retarded. But it's an obvious truism, I believe.

Anytype is unavoidable, when you need a container for heterogenous data or want to work with data of unspecified type. It's also very helpful in implementing a far- reaching flexibility, constrained properly by a documentation: like framework, plugin architecture, etc.
In C++ there's no other alternative, unless you're using a high- level framework, like Boost or Qt. Still, I think the generic type from those has only a minor advantage over void*, in terms of type safety. C++ is unable to store and utilize the type information a Java or C# does.

Any discussion about the two things above, in general terms, without refering to a specific problem, is worthless like a drunken talk about philisophy. It also leads to an unevitable:
'I've been writing business applications / graduation projects / whatever since 20 years, I got a ponytail reaching the ground, and I've never needed X, it's an inconsistency of design'.
Besides, methodology and logic of enterprise level programming doesn't necessary apply to small or tiny projects, especially games.

My comment on composition was a joke that appearently failed. I've seen C++ courses, where the authors, despite being rational people, went so far with their purism and object paradigm, they claimed composition is a bad trait derived from C and inheritance should be preferred universally over it... and it's an amazingly popular belief IRL.
And talk about composition over inheritance as proper solution in OP's case is too far- fetched. Objects of game world as class structure using extensively polymorphism etc, is good as anything else, if done properly.
The major drawback is rigidness, game- related things hardcoded into other program parts. As for me, it's one of the programming traits I sincerely hate.

As for virtual methods, it's good to know they're inefficient in programming fo embedded systems. It would be really helpful if the thread was about writing software for space sattelites, dvd players and vibrators- instead of PC and mobiles as it likely is.
The performance loss is in fact not a problem, since the CPUs got more than those ~100mhz and 1 level of cache.
Even if runtime penalty was significant (it doesn't), then think how much performance on modern hardware could you lose in a game, with truly prosperous code (class structure, not some dumbfuck algorithms etc) without any compiler optimization. 2 FPS? 5 FPS?
I am not an apologist of poorly written code because heheh CPU is so fast nobody notices, but want to point out the runtime penalty problem insinsignificant now; it's an academic problem analysed when it's needed to test a compiler, not a performance problem for user.

What are 'design penalties' of virtual methods, again?

And in the end, it's good you mentioned your programming- related work and experience. Now everything you write looks smarter and more trustworthy, even I must admit it. Personally I don't see any need for stating such things.

(seriously, I have nothing better to do now )

I don't understand shit from what you posted.

Oh, that's bad. I hope others found this little exchange of views amusing and somehow informative.

I'm confused here (by a lot of things), when you mean "prosperous" code, you mean proper code, or code that seems to be made by prosper?

The latter one

Code:

class CNamedObject
{
public:
    CNamedObject() : m_nType(0), m_pVal(0)
    {
    }

    CNamedObject(string strname, int nType) : m_name(strname), m_nType(nType)
    {
    }

    void SetName(string strVal) { m_name = strVal; }
    void SetType(int nVal) { m_nType = nVal; }
    void SetValue(void* pTypeVal) {m_pVal = pTypeVal; }

    string GetName() { return m_name; }
    int GetType() { return m_nType; }
    void* GetValue() { return m_pVal; }
    
    
private:
    string m_name;
    int m_nType;
    void* m_pVal;
    
};

enum {
    PointerType_Int = 0,
    PointerType_Bool,
    PointerType_Char,
    PointerType_Float,
    PointerType_CustomTypeABC,
    PointerType_CustomTypeABD


};

You can store like and unlike things side by side and set a name for each. it won't get better than that. use a vector and you are elite!

Visual Studio is the best IDE out there by far. Anything with a comparable feature set (Eclipse on its best day) is laggy and has an inconsistent interface.
