Classes in Classes

[kevin06s]

I am having trouble getting a function to work in Visual C++. I have a Point class:

class Point {
private:
	int x;
	int y;
public:
	Point();
	void setX(int);
	void setY(int);
	int getX();
	int getY();
};

Point::Point() {
	x = 0;
	y = 0;
}

void Point::setX(int value) {
	x = value;
}

void Point::setY(int value) {
	y = value;
}

int Point::getX() {
	return x;
}

int Point::getY() {
	return y;
}

which is in another class

class EntityBase {
private:
	Point position;
public:
	Point getPos();
};

Point EntityBase::getPos() {
	return position;
}

and that class has a derived class

class Player : public EntityBase {
}p1;

When I try to do p1.getPos().setX(10), it does not do anything. In debug mode x and y of position always stay at 0. Am I doing something wrong? Should I have a setX() function in EntityBase?

You need to have your getPos() function either return a reference to your point (which is not recommended since it would kind of defeat the point of having position private), or Create a setX() function in EntityBase that just calls position's setX().

Thank you. That seems to have worked.
