« on: November 10, 2014, 04:09:48 pm »

What do you think? it's a game in progress.
You move by arrows, shoot by space.Sometimes bonuses apear on the screen, if you run into them you shoot faster.
Start by pressing 's'

Graphics / i guess it's about textures (loading circle problem)

« on: November 07, 2014, 07:53:07 pm »

Hey guys. I am making an Space invaders type of game, and i want to make some power-ups.I want to make an animation for that, like an loading circle so that user can know how much time left he has to take the power-up.I know how to do that by sprites(5-6 sprites with 1/5-1/6 of circle and just display the images after a time) but i want to do it smoothly, and by that i mean to calculate the % of circle to fill based on the time i want.I guess it can be done with texture updating...but i don't know

sf::Event event;
    sf::Texture texture_patrat;
    sf::Texture texture_background;
    texture_patrat.loadFromFile("Patrat.png");
    texture_background.loadFromFile("Background.png");
    sf::Sprite patrat;
    sf::Sprite background;
    patrat.setTexture(texture_patrat);
    background.setTexture(texture_background);
    sf::VideoMode screen=sf::VideoMode::getDesktopMode();
    sf::RenderWindow window(sf::VideoMode(800,600), "SFML window",sf::Style::Fullscreen);
    window.setFramerateLimit(30);
    sf::Vector2f dimensiuni;
    float newsizea,newsizeb;
    newsizea=screen.width/1680;
    newsizeb=screen.height/1050;
    sf::Vector2f x,y;
    x=patrat.getScale();
    y=background.getScale();
    background.setScale(x.x*newsizea,x.y*newsizeb);
    patrat.setScale(y.x*newsizea,y.y*newsizeb);

        {
            if(event.type == sf::Event::KeyPressed)
            {
                if(event.key.code==sf::Keyboard::Escape)
                {
                    window.close();
                }
                if(event.key.code==sf::Keyboard::Up&&dimensiuni.y-20>=0)
                {
                    dimensiuni.y-=20;
                    patrat.setPosition(dimensiuni.x,dimensiuni.y);
                }

                    patrat.setPosition(dimensiuni.x,dimensiuni.y);
                }
                if(event.key.code==sf::Keyboard::Down&&dimensiuni.y+20>screen.height-200)
                {
                    dimensiuni.y=screen.height-200;
                    patrat.setPosition(dimensiuni.x,dimensiuni.y);
                }
                if(event.key.code==sf::Keyboard::Right&&dimensiuni.x+20<=screen.width-200)
                {
                    dimensiuni.x+=20;
                    patrat.setPosition(dimensiuni.x,dimensiuni.y);
                }
                if(event.key.code==sf::Keyboard::Right&&dimensiuni.x+20>screen.width-200)
                {
                    dimensiuni.x=screen.width-200;
                    patrat.setPosition(dimensiuni.x,dimensiuni.y);
                }
                if(event.key.code==sf::Keyboard::Left&&dimensiuni.x-20>=0)
                {
                    dimensiuni.x-=20;
                    patrat.setPosition(dimensiuni.x,dimensiuni.y);
                }
                if(event.key.code==sf::Keyboard::Left&&dimensiuni.x-20<0)
                {
                    dimensiuni.x=0;
                    patrat.setPosition(dimensiuni.x,dimensiuni.y);
                }
            }
        }
        window.draw(background);
        window.draw(patrat);
        window.display();
    }
    return 0;
}

My problem is that if i use sprite.setScale(0.5,0.5) it works but if i use sprite.setScale(newsezia,newsizeb) it doesn't work.I don't know why the setScale doesn't work if i use variables but with numbers it works.

Graphics / Error, window.draw

« on: March 14, 2013, 05:15:09 pm »

Hey guys, i'm new at sfml. I want to draw 2 images but i get 2 errors:
25|error: 'desenbackground' was not declared in this scope|
26|error: 'desenpatrat' was not declared in this scope|

here is the code

#include <SFML/Graphics.hpp>
int main()
{
    sf::RenderWindow window(sf::VideoMode(800, 600), "SFML window");
    while (window.isOpen())
    {
         sf::Texture texture;
         if (!texture.loadFromFile("Background.png"))
            return EXIT_FAILURE;
         sf::Sprite desenbackground(texture);
         if (!texture.loadFromFile("Patrat.png"))
            return EXIT_FAILURE;
         sf::Sprite desenpatrat(texture);
    }
    while (window.isOpen())
     {
         sf::Event event;
         while (window.pollEvent(event))
         {
             if (event.type == sf::Event::Closed)
                 window.close();
         }

         window.clear();
         window.draw(desenbackground);
         window.draw(desenpatrat);
         window.display();
     }

     return EXIT_SUCCESS;
 }
