Hehehehe. Guys, back into the subject. The only problem implementing a base class is that anyone can create a custom class inherited from the base class, override methods, skip all the base class constructors and then add it to an array or pass it to a function. Then there seems to be no way to check if this custom class implements the class template.

So you make the constructor(s) private and then only classes in the same module can inherit from it.

WOW. Great idea, cool man, thanks for everything.
That surely will work, i don't know why i didn't think about that before...i guess i'm not smart enough.
