tmxlite

Description

A lightweight C++14 parsing library for tmx map files created with the Tiled map editor. Requires no external linking, all dependencies are included. Optionally Zstd support can be enabled by linking the required external library. Fully supports tmx maps up to 1.0 (see here) with CSV, zlib and base64 compression. Also supports some features of newer map versions (see below). The parser is renderer agnostic, and is cross platform on Windows, linux and macOS. It has also been successfully built for Android too.

As the library contains no specific rendering functions some example projects are included, along with the relevant CMake files. These are meant mostly for guidance and are not 100% optimised, but should get you off on the right foot when using libraries such as SFML, SDL2 or directly with OpenGL. Examples for any specific rendering library are welcome via a pull request.

Other Features

As well as full support for maps up to version 1.0, tmxlite also supports these features found in newer versions of the tmx specification:

• Object Templates - Templates (and any associated tile sets) are automatically loaded and parsed if found. Object properties are transparently handled so that objects can be read from an ObjectGroup as if they were unique instances. If an Object uses a templated tileset then Object::getTilsetName() will contain a non-empty string which can be used as a key with Map::getTemplateTilesets() to retrieve the associated tileset data.
• Infinite Maps - Maps with the 'infinite' flag set, and saved in either CSV or base64 (compressed and uncompressed) format are supported. A TileLayer will return an empty Tile vector in these cases, and tile ID data can be retrieved instead with TileLayer::getChunks() which returns a vector of chunk data that makes up the tile layer.
• Parallax layers - the parallax offset property of layers is parsed, as well as each map's parallax origin, if they exist
• Layer tint colours
• Extended tag support such as class

By default tmxlite supports zlib compressed maps, however gzip and zstd compression can be enabled at compile time, by linking the relevant external libraries:

Zstd compression

Tmxlite supports maps using Zstd compressed tile layers, however Zstd needs to be linked externally. To configure CMake or meson to use Zstd add the definition USE_ZSTD and set it to true. You may also configure your project manually, and add -DUSE_ZSTD to the compiler options. If you are using the USE_EXTLIBS option (see below) this is automatically configured for you.

Building

Either use the included Visual Studio project file if you are on Windows or the CMake file to generate project files for your compiler of choice. tmxlite can be built as both static or shared libraries, or simply include the source files in your own project. The following options are available for CMake configuration:

• TMXLITE_STATIC_LIB - Set this to true to build a static library, default false
• PROJECT_STATIC_RUNTIME - Statically link the cstd libraries, default false
• USE_RTTI - Enable runtime type information, default true
• USE_EXTLIBS - Use externally linked pugixml, zlib and Zstd libraries, default false
• USE_ZSTD - Use externally linked Zstd library, required for Zstd compressed maps. Default is false, but is overridden if USE_EXTLIBS is true

Configuring with meson is also possible, see meson_options.txt for details.

Quick Start

There is a getting started page on the Github wiki here.

Examples

The repository contains the following rendering examples:

• OpenGL Example
• SFML Example
• SDL2 Example

Examples are generally maintained by the community and offer varying amounts of functionality. All of them will render the included example tile maps at the very least, and some include more complex features such as animated tiles or individual tile flipping.

API Documentation

Doxygen generated API documentation can be found online here or generated with doxygen using the doxy file in the tmxlite/documentation/ directory.

Important information

tmxlite uses pugixml and miniz which are included in the repository, although external zlib and pugixml libraries can be used. Add -DUSE_EXTLIBS to your compiler's definitions or when configuring CMake set USE_EXTLIBS to TRUE. This will also automatically include Zstd.
