How would I create a class that would inherit only some abilities of a MC so that all it can do is hold a shape drawing and have an x,y, width, and height. Is this possible. My goal was to not use MC to hopefully raise frame rate and have a better running speed, seeing as a MC instance has a lot of “unneeded” member functions and veriables.  
\*\*Another question is it even possible to inherit the “draw” function that a MC has in order redraw on a shape on every frame.  
I hope someone can help me on this, because if this isn’t possible I’m gonna have to go back to C++.
