General discussions / Why does sf::Packet convert to big endian?

« on: March 02, 2016, 07:47:56 pm »

Windows and OS X are little endian. Linux can theoretically be big endian, but today pretty much 100% use little endian.
Converting to big endian seems like waste of cpu. Is there something I'm missing?

I think the new_building has to be char *

Graphics / making a rectangle enclosing a text

« on: May 26, 2015, 06:05:51 am »

float height = m_text.getFont()->getLineSpacing(m_text.getCharacterSize()) / 2.f;
m_rect.setSize({ m_rect.getSize().x, m_text.getLocalBounds().height + height});
window.draw(m_text); window,draw(m_rect);

when the text has letters it looks fine


but when the text is just like "..." the rectangle's height is shorter than it should be


how can i solve this issue?

file -new - project - empty project.

add all your files and libraries again then try to compile and run it

SFML projects / Re:creation - a top down action rpg about undeads

I'm thinking about it and this can be a lot more efficient than what I use now. (Faster iteration, less cache misses, object pools...)
And I'll possibly implement it this way at some point in future and I won't have to change lots of code. (There's no need for it now though, as I don't see any perfomance related issues with the stuff I have now).
The only thing which I can't figure out is how to actually create arrays for each component and then easily get it.
For example, suppose I want to be able to get some component this way:

auto mc = get<MovementComponent>(entityId);

So, I need some kind of type/component array mapping. And while the key can be a std::type_index, what will the value of the map be? I can't store arrays of different types in one std::map.

The way i implemented that is assigning unique ids(starting at 0) to each component at compile time.
Then you store these components in a vector.
Then you can retrieve each component by its id.
If an entity doesn't have that component, it can return nullptr.

template <class C>
C * get(int id)
{
     std::vector<Component*> & v = getComponentsofEntity(id);
     return static_cast<C*>(v[C::getUniqueID()]);
}

Graphics / What is wrong with my code?

« on: May 06, 2015, 05:13:59 am »

Hello, i'm building my own gui system.

i have a Container class that derives from sf::Transformable and stores children widgets. I also have a Panel class that derives from Container.
When I set a child widget's position, I want it to be relative to the parent's position.

auto panel = ui::Panel::create();
panel->setSize({ 100.f, 100.f });
panel->setPosition({ 50.f, 50.f });
panel->color = sf::Color::Blue;

auto panel2 = ui::Panel::create();
panel2->setSize({ 50.f, 50.f });
panel2->color = sf::Color::Green;

panel->add(panel2);

...
ui.add(panel);
window.draw(ui);
 

Since I never moved Green panel's position, I expect it to be at the same position as the Blue panel. However in my program it appears at 50, 50 relative to the blue panel.

What I get


What I expect

void Panel::draw(sf::RenderTarget & target, sf::RenderStates states) const
{
        states.transform *= getTransform();
        sf::RectangleShape r;
        r.setFillColor(color);
        r.setSize(getSize());
        target.draw(r, states);
        Container::draw(target, states);
}

void Container::draw(sf::RenderTarget & target, sf::RenderStates states) const
{
        states.transform *= getTransform();
        for (auto w : m_widgets)
                target.draw(*w, states);
}

What's wrong?

Audio / crash with sf::Music

« on: May 03, 2015, 06:54:36 pm »

I'm using phsfsstream class from here: https://github.com/SFML/SFML/wiki/Source%3A-PhysicsFS-Input-Stream

#include "PhysfsStream.h"
#include <SFML/Audio.hpp>
#include <iostream>

int main(int argc, char* argv[])
{      
        PHYSFS_init(argv[0]);
        PHYSFS_addToSearchPath("musics", 1);

        sf::Music music;
        PhysfsStream stream;
        stream.open("sample.ogg");
        music.openFromStream(stream);
        music.play();
       

        //music.stop(); //adding this line will prevent the program from crashing

        PHYSFS_deinit();
}

this program crashes saying "pure virtual function call", but if I stop the music before it goes out of scope, it won't crash. Is this a bug in SFML?

using visual studio 2013 and sfml 2.2

Network / Re: accepting a socket that has already been accepted

« on: April 15, 2015, 08:38:44 pm »

If a socket has been accepted, any request to be re-accepted will be ignored until the original connection is terminated.

As soon as another connection request arrives, the previous one will be disconnected.

I think these are 2 conflicting responses. So does the previous connection get disconnected or not?
