"TargetClass"

Hi there /prog/

Is something like this possible?

For example, let's say that I have two classes:

class MyWorld
{
    public:
        MyWorld();
        void setup();
        void draw();
    //
};
...
class OtherWorld
{
    public:
        OtherWorld();
        void setup();
        void draw();
    //
};

Then, I'd like to have a "TargetWorld" class, where for example:


TargetWorld targetWorld;

targetWorld = myWorld;
...
targetWorld = otherWorld;

Then, I'd like to be able to call

targetWorld.draw();
targetWorld.setup();

And that would call the initial class's method.  I was thinking about using templates or class inheritance and virtual methods, but I'm not sure if that's the right path.

not sure about your problem but initialize your virtual function as 0.
#include <iostream>

class TargetWorld
{
    public:
        TargetWorld();
        virtual void setup() = 0;
    //
};


TargetWorld::TargetWorld()
{
    //
}

class MainMenuWorld : public TargetWorld
{
    public:
        MainMenuWorld();
        void setup();
    //
};

MainMenuWorld::MainMenuWorld()
{
    //
}

void MainMenuWorld::setup()
{
    std::cout << "Reached me!" << std::endl;
}

int main(){
  TargetWorld *tw = new MainMenuWorld();
  tw->setup();
  return 0;
}
