Functions in classes

[connorvba]

I am hesitant to post this topic because it is the second time today that I have posted with a similar question, but I really can't figure out what is wrong. I have some simple code that moves a player in the direction you give them by changing a x,y,and z axis value. The problem that I am having is that I want to give a function access to another function, but they are in different classes and I don't know the correct syntax to do this. Here is the code that I have:

#include <iostream>
#include <limits>

class Move
{
public:
	int x;
	int y;
	int z;
	void move_player(int x,int y, int z);
};
class Menue
{
	public:
	Move movement;
	void menue_main(void move_player(int x, int y, int z));
};

int main()
{
	Menue main;
	std::cout<<main.Menue::menue_main(move_player(main.movement.x,main.movement.y, main.movement.z))<<std::endl;
	return 0;
}

void Move::move_player(int x,int y,int z)
{
	char direction;
	std::cout<<"Which direction will you move?"<<std::endl;
	std::cin>>direction;
	std::cout<<std::endl;
	if (direction = 'n')
	{
		x++;
		std::cout<<"You move north"<<std::endl;
	}
	if (direction = 's')
	{
		x--;
		std::cout<<"You move south"<<std::endl;
	}
	if (direction = 'e')
	{
		y++;
		std::cout<<"You move east"<<std::endl;
	}
	if (direction = 'w')
	{
		y--;
		std::cout<<"You move west"<<std::endl;
	}
	if (direction = 'u')
	{
		z++;
		std::cout<<"You move up"<<std::endl;
	}
	if (direction = 'd')
	{
		z--;
		std::cout<<"You move down"<<std::endl;
	}
}

void Menue::menue_main(movement.move_player(movement.x,Menue::movement.y,movement.z))
{
	char menue_input;
	std::cout<<"What would you like to do?"<<std::endl;
	std::cout<<"m:move"<<std::endl;
	std::cin>>menue_input;
	std::cout<<std::endl;
	if (menue_input = 'm')
	{
		movement.move_player(movement.x,movement.y,movement.z);
	}
	else
	{
		std::cout<<"I do not understand '"<<menue_input<<"'"<<std::endl;
	}
}

If someone could please explain to me what I am doing wrong that would be great. Thanks!

see the changes.. also, while testing for conditions use "==" and not "=". read the difference between them.

#include <iostream>
#include <limits>

class Move
{
public:
	int x;
	int y;
	int z;
	void move_player(int x,int y, int z);
};

class Menue
{
	public:
	Move movement;
	void menue_main();
};

int main()
{
	Menue main;
	main.menue_main();
	return 0;
}

void Move::move_player(int x,int y,int z)
{
	char direction;
	std::cout<<"Which direction will you move?"<<std::endl;
	std::cin>>direction;
	std::cout<<std::endl;
	if (direction == 'n')
	{
		x++;
		std::cout<<"You move north"<<std::endl;
	}
	if (direction == 's')
	{
		x--;
		std::cout<<"You move south"<<std::endl;
	}
	if (direction == 'e')
	{
		y++;
		std::cout<<"You move east"<<std::endl;
	}
	if (direction == 'w')
	{
		y--;
		std::cout<<"You move west"<<std::endl;
	}
	if (direction == 'u')
	{
		z++;
		std::cout<<"You move up"<<std::endl;
	}
	if (direction == 'd')
	{
		z--;
		std::cout<<"You move down"<<std::endl;
	}
}

void Menue::menue_main()
{
	char menue_input;
	std::cout<<"What would you like to do?"<<std::endl;
	std::cout<<"m:move"<<std::endl;
	std::cin>>menue_input;
	std::cout<<std::endl;
	if (menue_input = 'm')
	{
		int x, y, z;
		std::cout << "where you want to move it, enter x, y, z;" << std::endl;
		std::cout << "x: ";
		std::cin >> x;
		std::cout << "y: ";
		std::cin >> y;
		std::cout << "z: ";
		std::cin >> z;
		movement.move_player(x, y, z);
	}
	else
	{
		std::cout<<"I do not understand '"<<menue_input<<"'"<<std::endl;
	}
}

Thank you so much! I can finally continue with this project.
