LDtkLoader is a loader for LDtk tile maps.
You can use it to load LDtk levels in your game and access any data you need via the API.
A taste of simplicity :
// load the file
ldtk::World world;
world.loadFromFile("my_levels.ldtk");
// get a level
const auto& level1 = world.getLevel("Level1");
// get a layer
const auto& bg_layer = level1.getLayer("BgLayer");
// iterate on the tiles of the layer
for (const auto& tile : bg_layer.allTiles()) {
// do something with the tile (storing, rendering ...)
}
// iterate on Enemy entities
for (const auto& enemy : level1.getLayer("Entities").getEntities("Enemy")) {
// iterate over an array field of Enum values
for (const auto& item : enemy.getArrayField<ldtk::EnumValue>("items")) {
// test if field is null
if (!item.is_null()) {
// do something with item
if (item == world.getEnum("Items")["Sword"]) {
// the enemy has a Sword !
}
}
}
// get an Entity field
int enemy_hp = enemy.getField<int>("HP").value();
}
Should work with any C++11 compiler. (MSVC uses --config
to specify build type,
other compilers use the CMAKE_BUILD_TYPE
variable)
mkdir build && cd build
cmake [-DCMAKE_BUILD_TYPE={Debug|Release}] ..
cmake --build . [--config {Debug|Release}]
Additional CMake options you can pass :
-
-DLDTK_NO_THROW
: to print message and exit when there is an error instead of throwing exceptions -
-DBUILD_API_TEST
: to build the API test example, to make sure the library works as expected -
-DBUILD_SFML_EXAMPLE=ON
: to build the SFML example (requires SFML installed)- set
-DSFML_ROOT=/path/to/SFML/
if CMake is unable to find it - set
-DSFML_STATIC_LIBRARIES=TRUE
if you want to link the static libraries
- set
-
-DBUILD_SDL_EXAMPLE=ON
: to build the SDL example (requires SDL2 and SDL2_image installed)
In the build directory, run :
cmake [-DCMAKE_INSTALL_PREFIX=/install/path/LDtkLoader] ..
cmake --install . [--config {Debug|Release}]
This will copy the libraries, the headers and the cmake config files to the install path.
After installation, to use the LDtkLoader library in your CMake project, you can just call :
find_package(LDtkLoader)
The find_package
command will automatically get the correct library (release or debug) depending on your current CMake configuration.
Then you only have to link the library to your target :
target_link_libraries(YourTarget PRIVATE LDtkLoader)
Note : if you installed LDtkLoader at a custom path, you might need
to pass a -DLDtkLoader_ROOT=/install/path/LDtkLoader
option to cmake so it can find the package.
Documentation is under construction and can be found on the wiki.
Alternatively, you can build the API documentation with doxygen using the provided Doxyfile.
