LibGDX removing tiles

What is the easiest way to stop an OrthogonalTiledMapRenderer from rendering specific tiles in real time? And is there a way to add tiles to the TiledMap on the fly as well? Thanks in advance.

You can use the Cell and Layer to manipulate this.

final Cell cell = new Cell();
final TiledMapTileSet tileSet = map.getTileSets().getTileSet("your tileset name");
// Set the cell to a tile, if tile is null, cell is clear
cb.setTile(tileSet.getTile(42));
layer.setCell(x, y, cell);

Hope this helps,
Fredrik
