General / SFML Game Development

« on: January 23, 2015, 06:32:10 am »

I am beginner in game development and trying to make a game called space craft but i have some problems and i can't define what they are so i have attached the error message with my code.If anybody can help it's appreciated.
Main.cpp

#include<iostream>
#include"Header.h"
using namespace std;
int main(){
        Game game;
        game.Run();

        system("pause");
        return 0;
}

Header.h

#include<SFML/Graphics.hpp>
using namespace sf;
class Game{
public:
        Game();
        void Run();
       

private:
        const Time TimePerFrame = seconds(1.f / 60.f);
        Time TimeSinceLastUpdate;
        bool IsMovingUp, IsMovingRight, IsMovingLeft, IsMovingDown;
        void HandlePlayerInput(Keyboard::Key key, bool IsPressed);


private:
        RenderWindow window;
        Texture Ptexture;
        Sprite Player;


private:
        void ProcessEvents();
        void Update(const Time TimePerFrame);
        void Render();
};


 

Definitions.cpp

#include<iostream>
#include<SFML/Graphics.hpp>
#include<SFML/System.hpp>
#include<SFML/Window/ContextSettings.hpp>
#include"Header.h"
using namespace std;

Game::Game(){
        TimeSinceLastUpdate = Time::Zero;
        window.create(sf::VideoMode(640, 480), "Game Application", Style::Default);

        if (!Ptexture.loadFromFile("plane.png")){
                cout << "Error !\n";
                return;
        }
        Player.setTexture(Ptexture);
        // Scalling the craft
        Player.setScale(0.5, 0.5);
        Player.setPosition(100.f, 100.f);
        IsMovingDown = IsMovingLeft = IsMovingRight = IsMovingUp = 0;
}

and this is the error messsage
