I'm not a c++ wizard, but I'm pretty sure this is an issue with SFML itself. I kept it really basic, but I'm having trouble with vector<Sprite>. Do I really have to list them all explicitly? A loop seems easiest, so that's how I tried, but I don't think push_back is working, according to my gdb debugger. As the subject says, I get a segmentation fault upon compilation of the following code:
#ifndef events_H
#define events_H
#include <SFML/Graphics.hpp>
#include <string>
class LiveEvents
{
public:
void Switchboard();
private:
union switches;
};
#endif
#include <events.hpp>
void LiveEvents::Switchboard()
{
sf::Event event;
switch (event.type)
{
case sf::Event::KeyPressed:
if(sf::Keyboard::isKeyPressed(sf::Keyboard::W))
// do stuff
break;
}
switch (event.type)
{
case sf::Event::KeyPressed:
if(event.key.code == sf::Keyboard::C)
//do stuff
break;
}
}
And the main loop:
#include <events.hpp>
#include <vector>
int main()
{
sf::RenderWindow screen(sf::VideoMode(800,600), "Window");
screen.setVerticalSyncEnabled(true);
screen.setFramerateLimit(60);
while (screen.isOpen())
{
sf::Event screen_event;
while(screen.pollEvent(screen_event))
{
switch(screen_event.type)
{
case sf::Event::Closed:
screen.close();
default:
break;
}
LiveEvents switches;
switches.Switchboard();
}
screen.clear(sf::Color::Black);
sf::Texture background;
if(!background.loadFromFile("../textures/background_rect.png"))
{
return -1;
}
sf::Sprite sprite;
sprite.setTexture(background);
int width = sprite.getGlobalBounds().width;
int height = sprite.getGlobalBounds().height;
std::vector<sf::Sprite> sprite_vector;
for(int i=0; i<3; i++)
{
sprite_vector[i].push_back(sprite);
}
for(int i=0; i<3; i++)
{
for(int j=0; j<3; j++)
{
sprite_vector[i].setPosition(sf::Vector2f(i*width,j*height));
}
}
for(int i=0; i<3; i++)
{
screen.draw(sprite_vector[i]);
}
screen.display();
}
}
Is there a better way to handle containers than vector<Sprite>? As it looks right now, I'll have to list all of them explicitly, and no way am I doing that. I've seen a few forum posts that say do this or that, but no one shows a simple example of how to display multiple sprites. Can someone please show me and/or point out what's wrong with my code?
edit: left out the push_back loop on accident. I must have changed something, but now I get
error: ‘__gnu_cxx::__alloc_traits<std::allocator<sf::Sprite> >::value_type’ has no member named ‘push_back’
sprite_vector[i].push_back(sprite);
