Graphics / Board for PacMan

A grid holding solid values would suffice (for both solids and drawing walls), then something like A* path finding could be used.

Use sf::Texture&

General / window is closing

I find that happens with some runtime errors. Tbh I don't mess with 1.6, you could try 2.0?

Window / Simple open-window tutorial problem...

« on: December 23, 2011, 03:57:50 am »

Have you got your events set up properly?

In main, somewhere after window create, something like this.

Code: [Select]

  sf::Event event;
   while (window.PollEvent(event))
   {
      switch(event.Type)
      {
      case sf::Event::Closed:
         return EXIT_SUCCESS;
         break;

      case sf::Event::KeyPressed:
         if (event.Key.Code == sf::Keyboard::Escape)
            return EXIT_SUCCESS;
         break;
      }
   }


Or returning from the programs execution window, window.Close().

Graphics / Printing Variables

« on: December 19, 2011, 03:39:13 pm »

Can be as easy as:

Code: [Select]

char out[16];
int score = 5;
sprintf(out, "Score: %i", score)
sf::Text text(out);
renderWindow.Draw(text);

General / Loading Resource

Would copying those dll's into the executables directory or into "\Windows\System" be sufficient? Or do you like them in a separate directory?

Graphics / sf::RenderImage::Create extremely slow

It's good that there's a function which is aware of this limit, very helpful, thanks.

Graphics / sf::RenderImage::Create extremely slow

A primitive test to see if it could handle the drawing efficiently when resized in runtime.

Code: [Select]


sf::RenderImage surface;
sf::Sprite surfaceSprite;
sf::Vector2i pos;  //Store mouse position, checks if changed

sf::RenderWindow window(sf::VideoMode(800, 600));
window.SetFramerateLimit(60);

while (window.IsOpened())
{
   sf::Event event;
   while (window.PollEvent(event))
   {
      // Window closed or escape key pressed : exit
      if (event.Type == sf::Event::Closed)
      {
         window.Close();
         break;
      }
   }

   window.Clear();

   //Surface test
   if (pos != sf::Mouse::GetPosition(window))  //Change if mouse moved
   {
      pos = sf::Mouse::GetPosition(window);
      surface.Create(pos.x, pos.y);  //This line
      surface.Clear(sf::Color::White);
      surface.Display();
   }

   surfaceSprite.SetImage(surface.GetImage());
   window.Draw(surfaceSprite);

   //Draw fps
   int temp = window.GetFrameTime();
   if (temp > 0)
   {
      char out[3];
      int fps = 1000 / temp;   //Some computers 1 / time works, for this pc only 1000 gives accurate amount
      itoa(fps, out, 10);
      sf::Text text(out);
      window.Draw(text);
   }

   //
   window.Display();
}


Reallocating an area for a surface per frame may be extreme, but achieving 17-18 of these a second is quite limiting. Just need a way to resize in a reasonable amount of time.

Yes, It is necessary to be able to do this, for this specific task.

I wouldn't be replying here if that faulty line of code weren't RenderImage's Create().

Is there a chance this could be sped up at all?

This does need to be addressed, It's incredibly slow. I can sit at a stable 500fps  then dip all the way down to 17/18 on some quite capable hardware. SDL 1.2 can achieve with its software blitting surfaces nicely.
