Install TiledCS

The easiest method is to create your MonoGame project then:

  1. Click on project & select Nuget Package Manager
  2. Search online for TiledCS & Install
  3. In the Game1.cs of your project add:
    using TiledCS;
    

You can also get the source code from the link below, and copy the `.cs` files into the same folder as your `Game1.cs` or in a new folder within this.

Drawing a Map

You will need to create the following variables within `Game1.cs`:

        TiledMap map;
        Texture2D ts;

In the `LoadContent` method of `Game1.cs` you need to add the following to load in the map:

            map = new TiledMap("Content/real.tmx");
            var tilesets = map.GetTiledTilesets("Content/"); // DO NOT forget the / at the end
            ts = Content.Load<Texture2D>(tilesets[1].Image.source.Split(".")[0]);

Finally in the `Draw` method of `Game1.cs` you need the following code to draw the map itself:

            var tilesets = map.GetTiledTilesets("Content/"); // DO NOT forget the / at the end
            var tileLayers = map.Layers.Where(x => x.type == TiledLayerType.TileLayer);

            _spriteBatch.Begin();
            foreach (var layer in tileLayers)
            {
                for (var y = 0; y < layer.height; y++)
                {
                    for (var x = 0; x < layer.width; x++)
                    {
                        var index = (y * layer.width) + x; // Assuming the default render order is used which is from right to bottom
                        var gid = layer.data[index]; // The tileset tile index
                        var tileX = (x * map.TileWidth);
                        var tileY = (y * map.TileHeight);

                        // Gid 0 is used to tell there is no tile set
                        if (gid == 0)
                        {
                            continue;
                        }

                        // Helper method to fetch the right TieldMapTileset instance. 
                        // This is a connection object Tiled uses for linking the correct tileset to the gid value using the firstgid property.
                        var mapTileset = map.GetTiledMapTileset(gid);

                        // Retrieve the actual tileset based on the firstgid property of the connection object we retrieved just now
                        var tileset = tilesets[mapTileset.firstgid];

                        // Use the connection object as well as the tileset to figure out the source rectangle.
                        var rect = map.GetSourceRect(mapTileset, tileset, gid);

                        // rect is not an actual rectangle, so create one for _spriteBatch to use.
                        Rectangle tilerec= new Rectangle(rect.x, rect.y, rect.width, rect.height);

                        // Render sprite at position tileX, tileY using the rect
                        _spriteBatch.Draw(ts, new Rectangle((int)tileX, (int)tileY, 32, 32), tilerec, Color.White);
                    }
                }
            }
            _spriteBatch.End();
