Title: Displaying text: Visual Studio RELEASE Mode.
Post by: Nikko_Bertoa on February 24, 2010, 07:25:01 pm

Hi community.

I'm making a game and I display text for health, FPS, etc.
When I compile and run in DEBUG MODE the text displays correctly, but when I compile the same code in RELEASE MODE the text doesn't display.

I have both modes with SFML_DYNAMIC, I setted the same libraries with -d for DEBUG MODE and without -d for RELEASE MODE.

I found the problem. I wrote SFML_DINAMIC not SFML_DYNAMIC in the Release Mode options.

This is my "main.cpp"

Code: [Select]


//
//  Headers
//
#include "GameManager.h"


//
// Main
//
int main(void)
{

GameManager gameManager;

gameManager.Run();

return EXIT_SUCCESS;

}




This is my "GameManager.h"

Code: [Select]



#ifndef GAMEMANAGER_H
#define GAMEMANAGER_H


//------------------------------------------------------------------------
//
//  Name:   GameManager.h

#include <SFML/Graphics.hpp>


class GameManager
{

public:

GameManager();

virtual ~GameManager();

void Run();


private:

sf::RenderWindow m_screen;

sf::Font* m_font;
sf::String* m_fpsText;

};


#endif // GAMEMANAGER_H



And this is my "GameManager.cpp"

m_font = new sf::Font();
assert(m_font->LoadFromFile("resources/fonts/arial.ttf"));
m_fpsText = new sf::String("Test Text", *m_font);
m_fpsText->SetSize(30.0f);
float xCoord = 10.0f;
float yCoord = 10.0f;
m_fpsText->SetPosition(xCoord, yCoord);
m_fpsText->SetStyle(sf::String::Regular);
m_fpsText->SetColor(sf::Color::White);

}


// Destructor
GameManager::~GameManager()
{

if(m_font != 0)
{

delete m_font;
m_font = 0;

}

if(m_fpsText != 0)
{

delete m_fpsText;
m_fpsText = 0;

}


}


void GameManager::Run()
{

// Start game loop
while (m_screen.IsOpened())
{
// Process events
sf::Event Event;
while (m_screen.GetEvent(Event))
{

// Close window : exit
if (Event.Type == sf::Event::Closed)
m_screen.Close();

}

// Clear the screen (fill it with black color)
m_screen.Clear();

m_screen.Draw(*m_fpsText);

// Display window contents on screen
m_screen.Display();

}

}


When I run the application in DEBUG MODE, I see the text. When I run the application in RELEASE MODE, I don't see the text. I'm using Visual Studio 2008.

Here is the definition of the assert macro in release mode:

Code: [Select]

#define assert(cond)
It evaluates to nothing, so whatever you put inside is never compiled in release mode.

So you should only put tests and comparisons into your asserts, not direct calls to functions that do something useful.

Thanks!!! I wrote:

Code: [Select]


bool correctLoading = m_font->LoadFromFile("resources/fonts/arial.ttf");
assert(correctLoading);


and now my application works!
