Question

我正在尝试完成图形处理教程并且卡在输入文件上。我的visual studio不接受.txt文件，尽管它在工作目录中并给它完整的路径名（C：/ - ＆gt;标识符是未定义的）不确定为什么第一行给出问题所以任何帮助理解这一点真的很感激。

std::ifstream openfile(C:/Users/RDT/Documents/Visual Studio 2017/Projects/TDS1/TDS1/Maps1.txt);
sf::Texture tileTexture;
sf::Sprite tiles;

sf::Vector2i map[100][100];
sf::Vector2i loadCounter = sf::Vector2i(0, 0);
    if (openfile.is_open())
    {
        std::string tileLocation;
        openfile >> tileLocation;
        tileTexture.loadFromFile(tileLocation);
        tiles.setTexture(tileTexture);
        while (!openfile.eof())
        {
            std::string str;
            openfile >> str;
            char x = str[0], y = str[2];
            if (!isdigit(x) || !isdigit(y))
                map[loadCounter.x][loadCounter.y] = sf::Vector2i(-1, -1);
            else
                map[loadCounter.x][loadCounter.y] = sf::Vector2i(x-'0', y-'0');
            if (openfile.peek() == '\n')
            {
                loadCounter.x = 0;
                loadCounter.y++;
            }
            else
                loadCounter.x++;
        }
        loadCounter.y++;
    }
    sf::RenderWindow Window(sf::VideoMode(640, 480, 32), "Loading Maps");
    while (Window.isOpen())
    {
        sf::Event Event;
        while (Window.pollEvent(Event))
        {
            switch (Event.type)
            {
            case sf::Event::Closed:
                    Window.close();
                    break;
            }
        }
        Window.clear();
        for (int i = 0; i < loadCounter.x; i++)
        {
            for (int j = 0; j < loadCounter.x; j++)
            {
                if (map[i][j].x != -1 && map[i][j].y != -1)
                {
                    tiles.setPosition(i * 32, j * 32);
                    tiles.setTextureRect(sf::IntRect(map[i][j].x = 32, map[i][j].y = 32, 32, 32));
                    Window.draw(tiles);
                }
            }
        }
        Window.display();

    }

}

除了提供给ng-file-select构造函数的路径之外，其他所有内容在您的代码中看起来都不错。我将建议一个简单的更改来解决这个问题。问题出在文件路径上。

openfile()

visual studio 2017上的openfile问题
