c++ - 从SFML 2.1中的 vector 中删除Sprites

我正在尝试从 vector 中删除精灵，但无济于事，我也不知道出了什么问题(VS 2010，SFML 2.1)。它根本无法编译。任何提示表示赞赏。

这行，似乎有问题:
SpriteVector.erase(std::remove(SpriteVector.begin(), SpriteVector.end(), SpriteIt), SpriteVector.end());
完整代码:

#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;
}

最佳答案

您将传递类型SpriteIt作为remove的最后一个参数，而不是要从容器中删除的值。
