General / Collision Detection Problems

« on: January 15, 2014, 03:12:21 am »

I've made a little toy program that draws a red and white square to the screen. The player controls the red square and when it collides with the white square I pick a random position on the screen to move the white square. It works when I collide with the white square once, but the second time I try to collide with it nothing happens. I think it might have something to do with the square's transformation and its bounding box or something, but I'm not familiar enought with sfml.

Here's the code for the collision:

bool collide(sf::RectangleShape cellOne, sf::RectangleShape cellTwo) {

        return cellOne.getGlobalBounds().intersects(cellTwo.getGlobalBounds());
}
 

Here's where it's called:

if (collide(redCell, whiteCell)) {
                whiteCell.setPosition(randomPosition());
        }

Window / How do I create a window?

« on: June 24, 2012, 04:48:33 am »

I'm off to a bit of a bumpy start here.  The application compiles and runs fine, but no window is displayed (except for the console). I'm following the "Opening a window" tutorial on this site. My OS is Windows Vista 32bit.

#include <SFML/Window.hpp>

int main()
{
    // Create the main window
    sf::Window app(sf::VideoMode(800, 600, 32), "SFML Window");

    // Start main loop
    bool running = true;
    while (running)
        app.Display();
 

    return EXIT_SUCCESS;
}
 

Is there something wrong with this code? It's the exact same code from the tutorial.

General / Tutorial Problem - Opening a Window

« on: November 21, 2011, 11:29:34 pm »

I've decided to give SFML a try so I started with the tutorials but it looks like I'm stuck right off the bat. I can't seem to create a window.

The code:

Code: [Select]


#include <SFML/Window.hpp>

int main()
{
sf::Window App(sf::VideoMode(800, 600, 32), "SFML Window");

while(App.IsOpened())
{
sf::Event e;
while(App.GetEvent(e))
{
// Close window
if(e.Type == sf::Event::Closed)
App.Close();
// Escape key pressed
if((e.Type == sf::Event::KeyPressed) && (e.Key.Code == sf::Key::Escape))
App.Close();
}

App.Display();
}

return EXIT_SUCCESS;
}


The command prompt appears, but no window. Any ideas? I'm using VC++ 2010 on Windows 7.
