I'm trying to remove sprites from a vector, but to no avail and I don't know what's wrong(VS 2010 with SFML 2.1). It simply doesn't compile. Any tips appreciated.
Its this line, that seems problematic:
SpriteVector.erase(std::remove(SpriteVector.begin(), SpriteVector.end(), SpriteIt), SpriteVector.end());
Full code:
#include <SFML/Graphics.hpp>
#include <iostream>
#include <vector>
#include <algorithm>
int main()
{
sf::RenderWindow mMainWindow(sf::VideoMode(1200, 900), "Map");
mMainWindow.setFramerateLimit(60);
sf::RectangleShape rect;
rect.setSize(sf::Vector2f(1500, 500));
sf::Texture unittexture;
unittexture.loadFromFile("sprite.png");
std::vector<sf::Sprite> SpriteVector;
std::vector<sf::Sprite>::iterator SpriteIt;
while (mMainWindow.isOpen())
{
sf::Event event;
while (mMainWindow.pollEvent(event))
{
if (event.type == sf::Event::Closed)
{
mMainWindow.close();
}
else if (event.type == sf::Event::KeyPressed && event.key.code == sf::Keyboard::A)
{
sf::Sprite newSprite;
newSprite.setTexture(unittexture);
newSprite.setPosition(mMainWindow.mapPixelToCoords(sf::Vector2i(sf::Mouse::getPosition(mMainWindow).x-50,sf::Mouse::getPosition(mMainWindow).y-50)));
SpriteVector.push_back(newSprite);
}
else if (event.type == sf::Event::MouseButtonPressed && event.mouseButton.button == sf::Mouse::Right)
{
// sf::Vector2f mousecoords(mMainWindow.mapPixelToCoords(sf::Vector2i(event.mouseButton.x, event.mouseButton.y)));
// SpriteVector.remove_if([=](sf::Sprite newSprite){return newSprite.getGlobalBounds().contains(mousecoords); }); //example code that would work with a list
SpriteVector.erase(std::remove(SpriteVector.begin(), SpriteVector.end(), SpriteIt), SpriteVector.end()); // This doesn't work and I don't know why.
}
}
mMainWindow.clear();
mMainWindow.draw(rect);
for(auto &SpriteIt = SpriteVector.begin();SpriteIt != SpriteVector.end();++SpriteIt)
{
mMainWindow.draw(*SpriteIt);
}
mMainWindow.display();
}
return 0;
}
