Graphics / Sprite.GetSubRect().Intersects() constantly returns true

« on: September 22, 2011, 02:27:32 am »

After trying to use sf::Sprite.GetSubrect().Intersects() I've come to find that no matter what, it always returns true. This can be tested with the following code:

Code: [Select]

#include <SFML/Graphics.hpp>
#include <SFML/Audio.hpp>
#include <SFML/System.hpp>
#include <iostream>
#include "games.h"

struct Square
{
    sf::Sprite Sprite;
    sf::Image Image;
    sf::String String;
    Square();
};

Square::Square()
{
    Image.Create(100, 100, sf::Color(255,255,255));
    Sprite.SetImage(Image);
    String.SetFont(sf::Font::GetDefaultFont());
}

int Collision_Test(sf::RenderWindow &App)
{
    Square S1, S2, S3;
    S1.Image.Create(100, 100, sf::Color(255,0,0)); // Red Square
    S2.Image.Create(100, 100, sf::Color(0,255,0)); // Green Square
    S3.Image.Create(100, 100, sf::Color(0,0,255)); // Blue Square
    S1.Sprite.SetPosition(250, 250); // Left Bottom
    S2.Sprite.SetPosition(375, 250); // Right Bottom
    S3.Sprite.SetPosition(300, 300); // Center Top
    S1.String.SetPosition(App.GetWidth()/2, App.GetHeight()/8);
    S2.String.SetPosition(App.GetWidth()/2, App.GetHeight()/6);
    bool Switched = false;
    while (App.IsOpened())
    {
        sf::Event Event;
        while (App.GetEvent(Event))
        {
            if (Event.Type == sf::Event::Closed)
            {
                App.Close();
            }

            if ((Event.Type == sf::Event::KeyPressed) && (Event.Key.Code == sf::Key::Escape))
            {
                App.Close();
            }
        }

        const sf::Input& Input = App.GetInput();
        bool Space_Down = Input.IsKeyDown(sf::Key::Space);
        if (Space_Down)
        {
            if (Switched)
            {
                S1.Sprite.SetPosition(250, 250); // Left Bottom
                S2.Sprite.SetPosition(375, 250); // Right Bottom
                S3.Sprite.SetPosition(300, 300); // Center Top
                Switched = false;
            }
            else
            {
                S1.Sprite.SetPosition(100, 250); // Left Bottom
                S2.Sprite.SetPosition(500, 250); // Right Bottom
                S3.Sprite.SetPosition(300, 500); // Center Top
                Switched = true;
            }
        }

        // Collision Logic
        if (S1.Sprite.GetSubRect().Intersects(S2.Sprite.GetSubRect()))
        {
            S1.String.SetText("Red is currently touching Green.");
        }
        else
        {
            S1.String.SetText("Red is not touching Green.");
        }
        if (S2.Sprite.GetSubRect().Intersects(S1.Sprite.GetSubRect()))
        {
            S2.String.SetText("Blue is currently touching Red.");
        }
        else
        {
            S2.String.SetText("Blue is not touching Red.");
        }



        App.Clear();
        App.Draw(S1.Sprite);
        App.Draw(S2.Sprite);
        App.Draw(S3.Sprite);
        App.Draw(S1.String);
        App.Draw(S2.String);
        App.Display();
    }
}

Audio / sf::soundbuffer plays no sound

« on: September 14, 2011, 10:34:18 pm »

sf::music works just fine for me, but for some reason playing a sound using sf::soundbuffer creates no response.

My code:

Code: [Select]


    // Init sounds
    sf::SoundBuffer hit_sb, step_sb;
    if (!hit_sb.LoadFromFile("audio/hit.wav") && step_sb.LoadFromFile("audio/step.wav"))
    {
        return EXIT_FAILURE;
    }
    sf::Sound step(step_sb);
    std::cout << "Duration: " << step_sb.GetDuration() << " Status: " << step.GetStatus();


It returns:

Code: [Select]

Duration: 0 Status: 0
