General / [SFML] Program slows down

« on: November 24, 2014, 04:49:21 pm »

#include <SFML/Graphics.hpp>

int main()
{
    sf::RenderWindow window(sf::VideoMode(640,480,32), "SFML works!");
    const float gravity = 0.0002f;
    int groundheight=440;
    const float moveSpeed = 0.1f,jumpSpeed = 0.2f;
    sf::Vector2f velocity(sf::Vector2f(0,0));
    sf::RectangleShape rect(sf::Vector2f(20,20));
    rect.setPosition(0,0);
    rect.setFillColor(sf::Color::Green);
    sf::Texture texture;
    sf::Texture Block;

    bool onGround = false;
    if(!texture.loadFromFile("map.png"))
    {

    }
    if(!Block.loadFromFile("block.png"))
    {

    }
    sf::Sprite backround(texture);
    backround.setPosition(0,460);

    sf::Sprite block(Block);
    block.setPosition(300,200);


    while (window.isOpen())
    {
        sf::Event event;
        while (window.pollEvent(event))
        {
            if (event.type == sf::Event::Closed)
                window.close();
        }
        if(sf::Keyboard::isKeyPressed(sf::Keyboard::Right))
        {
            velocity.x = moveSpeed;
        }
        else if(sf::Keyboard::isKeyPressed(sf::Keyboard::Left))
        {
            velocity.x = -moveSpeed;
        }
        else{
           velocity.x=0;
        }
        if(sf::Keyboard::isKeyPressed(sf::Keyboard::Space))
        {
            if(onGround==true)
            {
                  velocity.y = -jumpSpeed;
            }
        }
        if(rect.getPosition().y + rect.getSize().y < groundheight || velocity.y < 0)
        {
           velocity.y+=gravity;
           onGround=false;
        }
        if(rect.getGlobalBounds().intersects(backround.getGlobalBounds()))
        {
            velocity.y=0;
            onGround = true;
            rect.move(0,-0.01);
        }


        rect.move(velocity.x,velocity.y);


        window.clear();
        window.draw(backround);
        window.draw(rect);
        window.display();
    }

    return 0;
}
 

I dont know why but after about 8-10 seconds my game will just slow down to about half the original framerate.Any help would be appreciated.  Thanks
