TileMaps are maps made up of tiles. Each tile can have independent behavior.
TileMaps are stored in an XML-based map format called
TMX was originally
designed for tile-based maps but is also suitable for more generic game levels
due to its support for various object types.
TMX objects are easy to create:
// reading in a tiled map. auto map = TMXTiledMap::create("TileMap.tmx"); addChild(map, 0, 99); // with a tag of '99'
Tile-based maps can have many layers, determined by a z-order. You can access a specific layer by it's name:
// how to get a specific layer auto map = TMXTiledMap::create("TileMap.tmx"); auto layer = map->getLayer("Layer0"); auto tile = layer->getTileAt(Vec2(1, 63));
Each tile has a unique position and id. This makes it very easy to cherry pick specific tiles. You can access any tile by its id:
// to obtain a specific tiles id unsigned int gid = layer->getTileGIDAt(Vec2(0, 63));

How do you make a tiled-map? There are many tools that do this. Tiled is a popular tool. It is actively developed and has a great user community. The screen-shots above are actual Tiled projects.
