General / Getting an object from another file

« on: April 14, 2011, 03:08:45 am »

I haven't known C++ for long. I am learning by making a game with SFML.

I tried making a pointer of the instance of the sf::RenderWindow class. I couldn't quite get it to work. I also tried declaring the instance inside of my Window class, but I couldn't access it in my Input.cpp, so I just put it inside of an unnamed namespace (learned that from someone else's code).

General / Getting an object from another file

« on: April 12, 2011, 03:48:19 am »

I am trying to make a window class and an input handling class. I created an instance of sf::RenderWindow in the Window.cpp. I need to use this object in my Input.cpp file. What would be the best way of doing this?
Window.cpp

Code: [Select]


#include "Window.hpp"
#include <SFML/Graphics.hpp>
#include <SFML/Window.hpp>

namespace
{
       sf::RenderWindow window; //This is the object I need
       sf::Event Event;
}

Window::Window(int sizeX, int sizeY)
{
       width = sizeX;
       height = sizeY;
       scaleX = (scaleX * (width / 800));
       scaleY = (scaleY * (height / 600));
}

Input.cpp

Code: [Select]


#include "Input.hpp"
#include "Window.hpp"

#include <SFML/Graphics.hpp>
#include <SFML/Window.hpp>

namespace
{
       const sf::Input &input = window.GetInput(); //window not declared in this scope
}

Input::Input()
{
      while (input.IsKeyDown(sf::Key::Left)){
              Input::LeftKeyDown = true;}
      Input::LeftKeyDown = false;
