Title: simple private variable call problem
Post by: eradiuslore on March 28, 2011, 07:59:51 pm

hi im not sure if im just being a massive noob but im just trying to call a variable from my header and it just wont recognize it exists, what is it im doing stupidly wrong? and if possible could someone rearrange my code OR explain whats wrong. again bit of a noob.

game.h

Code: [Select]

#include <SFML/Graphics.hpp>


#pragma once


class game{

private:
sf::View view;

public:
game();
~game();
void initialise(sf::RenderWindow& App);
void update(sf::RenderWindow& App);
void render(sf::RenderWindow& App);
};

game.cpp

Code: [Select]

#include "game.h"

game::game(){}
game::~game(){}
void game::initialise(sf::RenderWindow& App){}

void game::update(sf::RenderWindow& App){

float Offset = 200.f * App.GetFrameTime();  
view.Move(0, -Offset);

}
void game::render(sf::RenderWindow& App){}

If it's private, it can only be used by functions inside the class. Have you tried making it public?
If you want it to be private, you have to declare a function inside the class to do the operation. In you case:

Code: [Select]


class Game
{ void move_view( int x, int y)
   { view.Move(x,y);
   }
...
};

He is accessing it from a member function of the class.

Can you give us the exact error message from the compiler?

In addition to what Groogy says - move your #pragma once to the top of the header-file.
