Graphics / Drawing with resetGLstates

« on: September 30, 2014, 05:48:51 am »

I'm using in my project SFGUI. And for drawing I'm using following code:

void render()
{
        glDisableClientState(GL_COLOR_ARRAY);
        m_rWindow->pushGLStates();

        glTranslatef(m_pos.x, m_pos.y, 0.0f);
        glPointSize(1.0f);
        glColor3f(0.7f, 0.7f, 1.0f);
        glDisableClientState(GL_COLOR_ARRAY);
        glDisableClientState(GL_TEXTURE_COORD_ARRAY);
        float vertData[] = {20.0f, 20.0f, 50.0f, 50.0f };
        glEnableClientState(GL_VERTEX_ARRAY);
                glVertexPointer(2, GL_FLOAT, 0, vertData);
                glDrawArrays(GL_POINTS, 0, 2);
        glDisableClientState(GL_VERTEX_ARRAY);
        m_rWindow->popGLStates();

        m_rWindow->resetGLStates();
        m_sfgui.Display(*m_rWindow);

}

glDrawArrays(GL_POINTS, 0, 2); - is drawed nothing

Why? What can I do for correct it?

As stated in the tutorials, you should not mix debug and release modes, i.e. you're linking the release libraries (without -d suffix) in debug mode. Change all the suffix to for example sfml-graphics-d.lib and it should work.

You're right! It works!

#include <SFML\Graphics.hpp>
#include <iostream>

int main(int argc, char* argv[])
{
        sf::RenderWindow window(sf::VideoMode(640, 480), "SFML Render");
        sf::Image image;
        sf::Texture texture;
        sf::Sprite sprite;

        image.loadFromFile("D:/Project/Sprites/bt1.png");
        texture.loadFromImage(image);
        sprite.setTexture(texture);
        sprite.setPosition(100.0f, 100.0f);

        sf::Event event;
        while (window.isOpen())
        {
                while (window.pollEvent(event))
                {
                        if (event.type == sf::Event::Closed)
                                window.close();
                }

                window.clear();
                window.draw(sprite);
                window.display();
        }

        return 0;
}

My configurations



code above is also crashes. Where I could go wrong?

If even I use following:
DoRender.cpp

#include "TApp.h"

void TApp::DoRender()
{
        sf::Texture texture;
        texture.loadFromFile("D:/Project/CPP/Game_Engine/Debug/sprites/first.bmp");

        sf::Sprite sprite(texture);
        sprite.setPosition(100.0f, 100.0f);


        m_Window.clear();
        m_Window.draw(sprite);
        m_Window.display();
}

occurs only a crash program. I tried use different kinds of path:

• D:/Project/CPP/Game_Engine/Debug/sprites/first.bmp
• D:\\Project\\CPP\\Game_Engine\\Debug\\sprites\\first.bmp
• d:\\Project\\CPP\\Game_Engine\\Debug\\sprites\\first.bmp

I use different files:

• D:/Project/Sprites/bt.png
• D:/Project/Sprites/anim.bmp
• D:/Project/Sprites/boy.jpg

Compiler indicates at following line:

texture.loadFromFile("D:/Project/CPP/Game_Engine/Debug/sprites/first.bmp");

More precisely, Program crashes on this line.

Okay. In this way, I tried to correct following:
TApp.h

#pragma once
#include <SFML\Graphics.hpp>


class TApp
{
public:
        TApp();

        int DoExecute();

private: /*MAIN FUNCTION*/
        void DoInputHandle();
        void DoUpdate();
        void DoRender();

private:
        sf::RenderWindow m_Window;
        sf::Texture m_texture;
        sf::Sprite m_sprite;
};

DoRender.cpp

#include "TApp.h"
#include <assert.h>
void TApp::DoRender()
{
        bool m = m_texture.loadFromFile("D:/Project/CPP/Game_Engine/Debug/sprites/first.bmp");
        assert(m == false);
        m_sprite.setTexture(m_texture);
        m_sprite.setPosition(100.0f, 100.0f);


        m_Window.clear();
        m_Window.draw(m_sprite);
        m_Window.display();
}

Not working! I remembered a relation between sf::Image - sf::Texture - sf::Sprite, and I thought that program is right now working, but not.
A few days ago I wrote following code:
main.cpp

#include <SFML\Graphics.hpp>
#include <boost\lexical_cast.hpp>
#include <iostream>
#include <string>

class Game
{
public:
        Game();
        void run();

private:
        void processEvent();
        void update(sf::Time deltaTime);
        void render();

private:
        sf::RenderWindow        mWindow;
};

int main()
{
        Game game;
        game.run();
        return 0;
}

Game::Game()
: mWindow(sf::VideoMode::getDesktopMode(), "SFML Window", sf::Style::Fullscreen)
{
}

void Game::run()
{
        sf::Clock clock;
        sf::Time timeSinceLastUpdate = sf::Time::Zero;
        const sf::Time TimePerFrame = sf::seconds(1.f / 60.f);
        while (mWindow.isOpen())
        {
                processEvent();
                timeSinceLastUpdate += clock.restart();
                while (timeSinceLastUpdate > TimePerFrame)
                {
                        timeSinceLastUpdate -= TimePerFrame;
                        processEvent();
                        update(TimePerFrame);
                }
                render();
        }
}

void Game::processEvent()
{
        sf::Event event;
        while (mWindow.pollEvent(event))
        {
                switch (event.type)
                {

                case sf::Event::Closed:
                        mWindow.close();
                        break;

                default:
                        break;
                }
        }
}

void Game::update(sf::Time deltaTime)
{
}

void Game::render()
{

        sf::Texture texture;
        texture.loadFromFile("D:/Project/CPP/Game_Engine/Debug/sprites/first.bmp");
       
        sf::Sprite sprite(texture);
        sprite.setPosition(100.f, 100.f);

        mWindow.clear();
        mWindow.draw(sprite);
        mWindow.display();
}

It's working. But why?? I confused.

I tried use also following:

#include "TApp.h"
#include <assert.h>
void TApp::DoRender()
{
        sf::Texture texture;
        bool m = texture.loadFromFile("D:/Project/CPP/Game_Engine/Debug/sprites/first.bmp");
        assert(m == false);
        sf::Sprite sprite(texture);
        sprite.setPosition(100.0f, 100.0f);


        m_Window.clear();
        m_Window.draw(sprite);
        m_Window.display();
}
 

Same error.

Graphics / Error load Image

I have follow code:
TApp.h

#pragma once
#include <SFML\Graphics.hpp>


class TApp
{
public:
   TApp();

   int DoExecute();

private: /*MAIN FUNCTION*/
   void DoInputHandle();
   void DoUpdate();
   void DoRender();

private:
   sf::RenderWindow m_Window;
   sf::Sprite m_sprite;
};

TApp.cpp

#include "TApp.h"

TApp::TApp()
: m_Window(sf::VideoMode(640, 480), "SFML Game Engine")
{
   sf::Texture texture;
   texture.loadFromFile("sprites/first.bmp");
   m_sprite.setTexture(texture);
}

int TApp::DoExecute()
{
   while (m_Window.isOpen())
   {
      DoInputHandle();
      DoUpdate();
      DoRender();
   }

   return 0;
}

int main(int argc, char* argv[])
{
   TApp application;
   return application.DoExecute();
}

DoInputHandle.cpp

#include "TApp.h"

void TApp::DoInputHandle()
{
   sf::Event event;

   while (m_Window.pollEvent(event))
   {
      switch (event.type)
      {
      case sf::Event::Closed:
         m_Window.close();
         break;

      default:
         break;
      }
   }
}

DoRender.cpp

#include "TApp.h"

void TApp::DoRender()
{
   m_Window.clear();
   m_Window.draw(m_sprite);
   m_Window.display();
}

DoUpdate.cpp

#include "TApp.h"

void TApp::DoUpdate()
{
}

It's very very simple. But haven't work.
Where may be an error?
