Tiled Map Editor loader for SFML

This repository contains:

• src/TmxLevel.h and src/TmxLevel.cpp — *.tmx file parser
• lib/tinyxml2/tinyxml2.h and lib/tinyxml2/tinyxml2.cpp — external library Tinyxml2 used to parse TMX format
• src/GameScene.h, src/GameScene.cpp, src/GameView.h, src/GameView.cpp, src/main.cpp — small demo application

My apprecations to:

• TMX loader class based on this article: habrahabr.ru/post/199064
• Original author http://en.sfml-dev.org/forums/index.php?topic=3023.0

Improvements comparing to original article:

• Optimized drawing: used faster object visiting in Debug builds and view rectangle clipping before draw:

void TmxLevel::Draw(sf::RenderTarget &target)const
{
    const sf::FloatRect viewportRect = target.getView().getViewport();

    // Draw all tiles (and don't draw objects)
    for (const auto &layer : m_layers)
    {
        for (const auto &tile : layer.tiles)
        {
            if (viewportRect.intersects(tile.getLocalBounds()))
            {
                target.draw(tile);
            }
        }
    }
}

• Tileset image described in <image> element now can handle "trans" attribute which defines backround color for transparent image.

• Load failure now causes exception, which can be catched in the following maner (in main() function):

try
{
    TmxLevel level;
    level.LoadFromFile("res/platformer.tmx");
}
catch (const std::exception &ex)
{
    std::cerr << ex.what() << std::endl;
    return 1;
}

• Classes renamed to have Tmx prefix

• Fixed a lot of warnings and important issues in coding style

Loader limitations

• It doesn't support compressed TMX files. You have to change your Tiled preferences to save as plain XML.
• It currently only handles one tilesheet. This shouldn't really be a problem.
• It currently has no support for isometric maps
