LDtkLoader is a loader for LDtk levels and tile maps.
Use it to load and get data from LDtk projects in your game.
Supports the entire .ldtk format (including external levels).
For loading older versions, see the Releases page.
A taste of simplicity :
// load the file
ldtk::Project ldtk_project;
ldtk_project.loadFromFile("my_project.ldtk");
// get a world
const auto& world = ldtk_project.getWorld("MyWorld");
// 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 ldtk::Entity& enemy : level1.getLayer("Entities").getEntitiesByName("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. You can select Debug or Release mode when building.
mkdir build && cd build
cmake -DCMAKE_BUILD_TYPE={Debug|Release} ..
cmake --build . --config {Debug|Release}This will generate the static library. Debug library has the suffix '-d'.
Additional CMake options :
-DLDTK_NO_THROW: to print message and exit when there is an error instead of throwing exceptions-DLDTK_BUILD_API_TEST: to build the API test example, to make sure the library works as expected-DLDTK_BUILD_SFML_EXAMPLE=ON: to build the SFML example (requires SFML installed)-DLDTK_BUILD_SDL_EXAMPLE=ON: to build the SDL example (requires SDL2 and SDL2_image installed)-DLDTK_BUILD_RAYLIB_EXAMPLE=ON: to build the raylib example (requires raylib 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 add LDtkLoader to a CMake project, use the find_package command:
find_package(LDtkLoader 1.5)The find_package command will automatically get the correct library (Release or Debug)
depending on your current CMake configuration.
Then, the library should be linked to the target:
target_link_libraries(YourTarget PRIVATE LDtkLoader)Note : if LDtkLoader is installed at a custom path, you might need
to pass a -DLDtkLoader_ROOT=/install/path/LDtkLoader option to cmake.
Documentation is under construction and can be found on the wiki.
