General / SFML2.1 No Window.PollEvent

« on: August 12, 2013, 11:33:49 pm »

I don't have a pollEvent function under Window or RenderWindow.
I'm using Ubuntu and my IDE is Qt.

I linked SFML in the project File(.pro) that is made when using Qt

TEMPLATE = app
CONFIG += console
CONFIG -= app_bundle
CONFIG -= qt

SOURCES += main.cpp \
    game.cpp

INCLUDEPATH += \Media\nickkorta\Shared\SFML-2.1\Linux\include
LIBS += -lsfml-system -lsfml-window -lsfml-graphics -lsfml-audio

HEADERS += \
    game.hpp

 

Here is my Game.h

#include "SFML/System.hpp"
#include"SFML/Graphics.hpp"
#include "SFML/Window.hpp"
#include "SFML/Audio.hpp"
#include "SFML/Network.hpp"


#ifndef GAME_HPP
#define GAME_HPP

class Game
{
public:
    Game();
private:
    void Initialize();
    void LoadContent();
    void Update();
    void Draw();
    bool running;
    sf::RenderWindow window;
    sf::Event event;
};

#endif // GAME_HPP
 

Game.cpp

#include "game.hpp"

Game::Game()
{
    Initialize();
    LoadContent();
    while(running)
    {
        Update();
        Draw();
    }
    window.Close();
}

void Game::Initialize()
{
    window.Create(sf::VideoMode(1080,720,32),"Game");
}

void Game::LoadContent()
{
}

void Game::Update()
{
    while (window.pollEvent(event))
    {
    }
}

void Game::Draw()
{
    window.Display();
    window.Clear();
}
 

Everything runs fine. I also noticed that I can move the window around and can use the maximize and minimize buttons. I have done this in windows and I cant do that without using Window.PollEvent(event).

Thanks

General / [Solved]Update function not working.

« on: August 07, 2013, 09:44:21 pm »

I have a very simple game class that has a update and draw function that calls on other classes update and function classes.

Game.h

#include <SFML/graphics.hpp>
#include "Unit.h"

#pragma once
class Game
{
public:
        Game(void);
        ~Game(void);
private:
        void Update();
        void Draw();

        sf::RenderWindow window;
        Unit unit;
};
 

game.cpp

#include "Game.h"


Game::Game(void)
{
        window.create(sf::VideoMode(800,600),"Game");

        while (window.isOpen())
        {
                Update();
                Draw();
        }
}


Game::~Game(void)
{
}

void Game::Update()
{
        sf::Event event;
       
        while (window.pollEvent(event))
        {
                if (event.type == sf::Event::Closed || event.key.code == sf::Keyboard::Escape )
                        window.close();
        }
        unit.Update(event);
}

void Game::Draw()
{
        window.clear(sf::Color(116,146,208));
        unit.Draw(window);
        window.display();
}
 

The problem is that my Unit class update function is not working but If I move the "Unit unit" object under game.h to game.cpp everything works just fine.

#include "Game.h"

Unit unit;

Game::Game(void)
{
        window.create(sf::VideoMode(800,600),"Game");

        while (window.isOpen())
        {
                Update();
                Draw();
        }
}


Game::~Game(void)
{
}

void Game::Update()
{
        sf::Event event;
       
        while (window.pollEvent(event))
        {
                if (event.type == sf::Event::Closed || event.key.code == sf::Keyboard::Escape )
                        window.close();
        }
        unit.Update(event);
}

void Game::Draw()
{
        window.clear(sf::Color(116,146,208));
        unit.Draw(window);
        window.display();
}

This brings me to the question is should I make objects and variables under Game.h or Game.cpp. Am im missing something fundamental.

Thanks

DotNet / Embed SFML Window in picturebox(Answered)

« on: August 01, 2013, 02:56:33 am »

Hi I'm using SFML.net 2.1. I'm trying to get a SFML window inside a picturebox but I am having no luck.

 public partial class Form1 : Form
    {
        private RenderWindow mapWindow;
        private bool running = true;

        public Form1()
        {
            InitializeComponent();
         
        }

        private void Draw()
        {
            Application.DoEvents();
            mapWindow.Clear(new SFML.Graphics.Color(101, 156, 239));
            mapWindow.Display();
            pictureBox1.Refresh();
        }

        private void Form1_FormClosed(object sender, FormClosedEventArgs e)
        {
            running = false;
        }

        private void pictureBox1_LoadCompleted(object sender, AsyncCompletedEventArgs e)
        {
            mapWindow = new RenderWindow(this.pictureBox1.Handle);
            while (running)
                Draw();
        }
    }

I did manage to get a SFML RenderWindow embedded inside the form.

 public partial class Form1 : Form
    {
        private RenderWindow mapWindow;
        private bool running = true;

        public Form1()
        {
            InitializeComponent();
         
        }

        private void Draw()
        {
   
            Application.DoEvents();
            mapWindow.Clear(new SFML.Graphics.Color(101, 156, 239));
            mapWindow.Display();
        }

        private void Form1_FormClosed(object sender, FormClosedEventArgs e)
        {
            running = false;
        }

        private void Form1_Load(object sender, EventArgs e)
        {
            mapWindow = new RenderWindow(this.Handle);
            while (running)
                Draw();
        }

    }

Thanks

Graphics / Window.Draw error LNK2001(Answered)

« on: July 31, 2013, 07:42:40 pm »

Hi I started using SFML with Visual Studio 2012 today.  Iv have not ran into any problems while rendering a Window , and using events such as keyboard, joystick , window and mouse. I'm trying to display an image on screen using the "Texture" and "Sprite" Class. My image is called "Mage" witch is a png file that is in the same folder as Main. I get this error when I use write "Window.Draw(sprite)".

Error   1   error LNK2001: unresolved external symbol "public: static class sf::RenderStates const sf::RenderStates::Default" (?Default@RenderStates@sf@@2V12@B)   c:\Users\nicho_000\documents\visual studio 2012\Projects\XXX\XXX\Main.obj

My Code

#include<SFML/Graphics.hpp>

void LoadContent();
void Update();
void Draw();

sf::RenderWindow window;
sf::Texture texture;
sf::Sprite sprite;

int main()
{
        window.create(sf::VideoMode(800,600),"Game");
        LoadContent();
        while (window.isOpen())
        {
                Update();
                Draw();
        }
}

void LoadContent()
{
        texture.loadFromFile("Mage.png");
        sprite.setTexture(texture);
}

void Update()
{      
       sf::Event event;
        while (window.pollEvent(event))
        {
                if (event.type == sf::Event::Closed || event.key.code == sf::Keyboard::Escape )
                        window.close();
        }
}

void Draw()
{
        window.clear(sf::Color(116,146,208));
        window.draw(sprite);
        window.display();
}

Thanks
