openfl4-tilemap-sample.hx

var tilesheet = Assets.getBitmapData("img/tilesheet.png");
var tileset = new Tileset(tilesheet);
var PATH = tileset.addRect(new Rectangle(0, 0, 32, 32));
var WALL = tileset.addRect(new Rectangle(0, 32, 32, 32));
var HERO = tileset.addRect(new Rectangle(0, 64, 32, 32));

//	TileMap is a DisplayObject so it can be added to the display list
//	we give it the same size as the stage so that we can use it as a layer
var tilemap = new Tilemap(Lib.current.stage.stageWidth, Lib.current.stage.stageHeight, tileset);
addChild(tilemap);
			
//	then we draw tile instances on it
tilemap.addTile(new Tile(PATH, 50, 100));
tilemap.addTile(new Tile(WALL, 150, 200));
tilemap.addTile(new Tile(HERO, 250, 300));
