Title: Processor gets hot and motherboard beeps
Post by: lobax on November 29, 2009, 01:07:18 am

Hi!

I was looking at the one of the tutorials, and decided to compile the one on  displaying a sprite.  But when i compile it, my computer starts beeping, and the tempeture of the processor just shoots up according to Core Temp (which i always have on). From a stable 30c it rockets up to 40c in less then a couple of seconds!

The program (which is the exact same as in the tutorial) does what it's supposed to do, and there are no errors what so ever from code::blocks.  

Code: [Select]

#include <SFML/Graphics.hpp>



int main()
{
    // Create the main rendering window
    sf::RenderWindow App(sf::VideoMode(800, 600, 32), "SFML Graphics");

    // Load the sprite image from a file
    sf::Image Image;
    if (!Image.LoadFromFile("you.bmp"))
        return EXIT_FAILURE;

    // Create the sprite
    sf::Sprite Sprite(Image);

    // Change its properties
    Sprite.SetColor(sf::Color(0, 255, 255, 128));
    Sprite.SetPosition(200.f, 100.f);
    Sprite.SetScale(2.f, 2.f);

    // Start game loop
    while (App.IsOpened())
    {
        // Process events
        sf::Event Event;
        while (App.GetEvent(Event))
        {
            // Close window : exit
            if (Event.Type == sf::Event::Closed)
                App.Close();
        }

        // Get elapsed time
        float ElapsedTime = App.GetFrameTime();

        // Move the sprite
        if (App.GetInput().IsKeyDown(sf::Key::Left))  Sprite.Move(-100 * ElapsedTime, 0);
        if (App.GetInput().IsKeyDown(sf::Key::Right)) Sprite.Move( 100 * ElapsedTime, 0);
        if (App.GetInput().IsKeyDown(sf::Key::Up))    Sprite.Move(0, -100 * ElapsedTime);
        if (App.GetInput().IsKeyDown(sf::Key::Down))  Sprite.Move(0,  100 * ElapsedTime);

        // Rotate the sprite
        if (App.GetInput().IsKeyDown(sf::Key::Add))      Sprite.Rotate(- 100 * ElapsedTime);
        if (App.GetInput().IsKeyDown(sf::Key::Subtract)) Sprite.Rotate(+ 100 * ElapsedTime);

        // Clear screen
        App.Clear();

        // Display sprite in our window
        App.Draw(Sprite);

        // Display window contents on screen
        App.Display();
    }

    return EXIT_SUCCESS;
}


The only thing i changed from the tutorial was "sprite.tga" to "you.bmp".

Any help in understanding the problem would be appriciated! Just please keep your answers simple, i'm a n00b att SFML ;)[/code]

The heating up is supposed to happen. Motherboards should be able to withstand somewhere around 70-80C. Not sure about the beeping though. Does the console give you any error messages?

It's because you don't sleep at all, the program is running as fast as it can on the processor. Use App.SetFramerateLimit(60); to make it run at 60 frames per second rather than as fast as possible.

Quote from: "Core Xii"

Use App.SetFramerateLimit(60); to make it run at 60 frames per second

Not exactly -> "Use App.SetFramerateLimit(60); to make it run at most 60 frames per second"

or use vsync, which usually gives a far more stable framerate and prevents tearing

is vsync on by default? I'm using App.setframerlimit(60) right after I create my window. (not in my loop)

My friends are reporting frame rates around 60-65. (It's running on 3 on my computer >_<)

what should I do?

What is the problem ?

(vsinc is sometimes set up in the GC-manager.)
