Graphics / strange and sharp object movement, due to SetFramerateLimit

« on: March 04, 2015, 06:08:41 pm »

Hello guys, I have a problem, as I know, SetFramerateLimit calls Sleep() to keep game framerate probably constant, but here's the problem, when I use

int main() {
RenderWindow Window(VideoMode(1024,768), "Window");
Window.setFramerateLimit(60);

RectangleShape rs;
rs.setSize(Vector2f(50,50));
rs.setPosition(0,0);

while(Window.isOpen()) {
rs.move(5,0);
Window.draw(rs);
Window.display();
Window.clear();
}
return 0;
}
 

that rectangle is moving very sharply every random frame and it can also move a bit back, or a bit forward, I don't know how to fix this :c

General / CPU core loaded to 100% when sfml app is launched

« on: February 08, 2015, 08:21:46 pm »

hello there guys, I have a problem, when I'm compiling that "test" code for sfml, I see that one of my core immediately become loaded from 1 - 3% to 80 - 100% and that's kinda strange, isn't that too much for an sfml or maybe that's my hardware issue ? Haven't tested this on other computers, here are screenshots :

General / NetBeans problem

« on: January 11, 2015, 04:06:12 am »

Hello guys, I have a problem with setting up SFML and NetBeans with minGW compiler. Looks like I connected all correctly, I'm using SFML 2.2 build for MinGW - 32bit





I'm trying to compile this simple code :

#include <SFML/Graphics.hpp>
 
int main()
{
    sf::RenderWindow window(sf::VideoMode(200, 200), "SFML works!");
    sf::CircleShape shape(100.f);
    shape.setFillColor(sf::Color::Green);
 
    while (window.isOpen())
    {
        sf::Event event;
        while (window.pollEvent(event))
        {
            if (event.type == sf::Event::Closed)
                window.close();
        }
 
        window.clear();
        window.draw(shape);
        window.display();
    }
 
    return 0;
}

and I get this error

tried reinstalling minGW twice and tried googling, but no result, that's why I'm here

Graphics / Problem with collision on Resizing

« on: December 23, 2014, 12:35:18 am »

Hello guys, I have a problem, I draw some squares in my window and they change their color, when I guide my cursor over them, but when I change manually the screen size, their collision is still on the last point, where it was, when those buttons haven't been resized, so, when I guide my cursor over them, there's nothing, but when I guide my cursor on that last place, squares change their color, any ideas what can I do ?

Graphics / GUI drawing

« on: December 11, 2014, 12:44:10 am »

hello guys, I have a question, how can I do something like glue GUI element to a current RenderWindow or current view ? I want that GUI to be a child of a view and I don't know how to do that, maybe you can guide me to the right path ?

Graphics / Problem with drawing text

« on: November 16, 2014, 07:47:47 pm »

Hello guys, I have a problem when I'm trying to draw more than one sf::Text, here's my source code

void GUI::CreateButton(sf::Vector2f position, sf::Vector2f size, sf::String text, sf::Vector2f textPos, sf::Texture buttonIMG, sf::Texture buttonGUIDANCE, sf::Texture buttonCLICK)
{
        std::unique_ptr<buttonSettings> rect (new buttonSettings()); // Creating a pointer to struct
 
                font.loadFromFile("D:\\visual studio 2012\\SFML_engine\\Project1\\Release\\Kingthings_Serifique.ttf");
        rect->btns.setPosition(position);

                rect->buttonIMG = buttonIMG;
                rect->buttonGUIDANCE = buttonGUIDANCE;
                rect->buttonCLICK = buttonCLICK;

               
        rect->btns.setSize(size);
                rect->btnText.setFont(font);
                rect->btnText.setCharacterSize(12);
                rect->btnText.setString(text);
                rect->btnText.setPosition(textPos);
        buttons.push_back(std::move(rect));
}

and then, after I've created a button with text, I'm drawing it :

for(unsigned int b = 0; b<buttons.size(); b++) { // draw buttons
                                _window.draw(buttons[b]->btns);
                                _window.draw(buttons[b]->btnText);
        }

and here, how my struct looks :

  typedef struct buttonSettings {
        sf::RectangleShape btns;
                sf::Text btnText;
                sf::Texture buttonIMG;
                sf::Texture buttonGUIDANCE;
                sf::Texture buttonCLICK;
        };

        std::vector<std::unique_ptr<ButtonListSettings>> buttonList;
 

all works fine, except one thing, when I'm creating more than one button with text, it's.. doing some strange things with one text.

« on: October 24, 2014, 02:30:33 pm »

Hello guys, I have a problem, I can't compile my program without debugging, with debugging it works perfectly, but without I have a crash, , when I start with debugging, it works : , here is my code : http://pastebin.com/tVBbdmHc, btw, it works, when I delete OnButtonListMove and CreateButtonList functions, I tried to replace that code, but still, no result, so, that's why I'm asking for a help, thanks.
