Hello!
I have no idea if this fits in here, but I’m posting it anyways.
I’ve created a Tiled json parser for Modern C++, and want to share it here in case it would be useful for someone. Any feedback is welcome! Also: If you find a bug, you are very welcome to report it.
If you have any suggestions on how to improve the library, I encourage you to share them 
You can find the parser here:
If this is inappropriate for this forum: Feel free to remove the post.
Sincerelly, Robin.
That is great that you provide another option for C++ developers! I’ve added your library here:
https://doc.mapeditor.org/en/latest/reference/support-for-tmx-maps/#id1
And to this new page, which is still a WIP and not linked from anywhere:
With the above page, I tried to make it easier to maintain and make the information a bit more structured. But I really don’t like working on websites…
Thank you very much for adding my library to the list!
Hope people find it useful!
As it is created to not only be a parser, but to have functionality to make it easier to use the data parsed in a project, I am very open for suggestions to improve the library, as well as keeping it updated with Tiled itself
Hello SSBM,
Thanks for sharing your work.
Sorry to pollute your topic but I got a trivial question.
Is there any way I can get a drawable object?
Could you eventually explain how?
(I’m a total newbie in Tiled and parsing (by the way the translation of “parser” in french is so foggy I’m not even sure I can use a parser in my project).
(If you have any tutorial in mind I can read or watch, it can be great too)
@RacheProu:
This is absolutely on topic, so no pollution at all. I do in fact encourage anyone to ask questions in cases where things are a little unclear
In short words, “parser” means “reader”. In other words, Tileson reads the data from Tiled maps in json format. You can get a tiled map in .json format by simply exporting it to json, and you will be able to parse/read the data from the map without any problem using C++ with ha modern compiler.
I just created another example in an attempt to help you using data to create drawable objects. Please go ahead and ask me further if you got more questions
This is a quickly written example just to showcase how you can use some of the data:
tson::Tileson t;
tson::Map map = t.parse("../../content/test-maps/ultimate_test.json");
if(map.getStatus() == tson::Map::ParseStatus::OK)
{
//Gets the layer called "Object Layer" from the "ultimate_demo.json map
tson::Layer *objectLayer = map.getLayer("Object Layer"); //This is an Object Layer
//Example from an Object Layer.
if(objectLayer->getType() == tson::Layer::Type::ObjectGroup)
{
tson::Object *goomba = objectLayer->firstObj("goomba"); //Gets the first object with this name. This can be any object.
//If you want to just go through every existing object in the layer:
for(auto &obj : objectLayer->getObjects())
{
tson::Vector2i position = obj.getPosition();
tson::Vector2i size = obj.getSize();
tson::Object::Type objType = obj.getObjectType();
//You may want to check the object type to make sure you use the data right.
}
tson::Object::Type objType = goomba->getObjectType();
/*!
* tson::Object::Type is defined like this.
* They are automatically detected based on what kind of object you have created
* enum class Type : uint8_t
{
Undefined = 0,
Object = 1,
Ellipse = 2, //<-- Circle
Rectangle = 3,
Point = 4,
Polygon = 5,
Polyline = 6,
Text = 7,
Template = 8
};
*/
if (objType == tson::Object::Type::Rectangle)
{
tson::Vector2i size = goomba->getSize();
tson::Vector2i position = goomba->getPosition();
//If you have set a custom property, you can also get this
int hp = goomba->get<int>("hp");
//Using size and position you can can create a Rectangle object by your library of choice.
//An example if you were about to use SFML for drawing:
//sf::RectangleShape rect;
//rect.setSize(sf::Vector2f(size.x, size.y));
//rect.setPosition(sf::Vector2f(position.x, position.y));
}
else if (objType == tson::Object::Type::Polygon)
{
for(auto const &poly : goomba->getPolygons())
{
//Set a point on a shape taking polygons
}
tson::Vector2i position = goomba->getPosition();
}
else if (objType == tson::Object::Type::Polyline)
{
std::vector<tson::Vector2i> polys = goomba->getPolylines();
for(auto const &poly : goomba->getPolylines())
{
}
tson::Vector2i position = goomba->getPosition();
}
}
tson::Layer *tileLayer = map.getLayer("Main Layer"); //This is a Tile Layer.
tson::Tileset *tileset = map.getTileset("demo-tileset"); //You will also need the tileset used
//by the tile map to make sense of everything
int firstId = tileset->getFirstgid(); //First tile id of the tileset
int columns = tileset->getColumns(); //For the demo map it is 8.
int lastId = (tileset->getFirstgid() + tileset->getTileCount()) - 1;
//Example from a Tile Layer
//I know for a fact that this is a Tile Layer, but you can check it this way to be sure.
if(tileLayer->getType() == tson::Layer::Type::TileLayer)
{
//pos = position in tile units
for(auto &[pos, tile] : tileLayer->getTileData()) //Loops through absolutely all existing tiles
{
fs::path imagePath;
std::string pathStr;
//With this, I know that it's related to the tileset above (though I only have one tileset)
if(tile->getId() >= firstId && tile->getId() <= lastId)
{
imagePath = tileset->getImagePath();
pathStr = imagePath.u8string();
}
//Get position in pixel units
tson::Vector2i position = {std::get<0>(pos) * map.getTileSize().x,std::get<1>(pos) * map.getTileSize().y};
int tileId = tile->getId();
//The ID can be used to calculate offset on its related tileset image.
int offsetX = (tileId % columns) * map.getTileSize().x;
int offsetY = (tileId / 8) * map.getTileSize().y;
//Now you can use your library of choice to load the image (like SFML), then set the offset
//to get the right image representation of the tile.
}
}
}
Edit:
To actually be able to draw any object you will need a library that is able to draw them. Tileson just gives you the data from Tiled to be able to know how to create them.
@SSBMTonberry
Thanks for this more precise than I could imagine.
It’s reassuring to see (at least I understood the base concept 
)
I’m very grateful for this!
I understand all the parts
I promise I will. 
Thanks!
