LibGDX: How to do animations on an isometric tiled map?
I've some problem with LibGDX and tiled maps. I come from Corona SDK (Lua) and I've used Lime (third party lib to handle tmx maps), now I switched to LibGDX and followed this really recent feature: GraphicsTileMaps
I was able to load an isometric map from assets using IsometricTiledMapRenderer as renderer and an OrthographicCamera to display the map (all works as described in the wiki page). I was also able to fill programmatically some tile on the map layer, but my problem starts, when I try to use AnimatedTiledMapTile :
map = new TmxMapLoader().load(...);
TiledMapTileLayer layer = (TiledMapTileLayer) map.getLayers().getLayer("layer1");
TiledMapTileSet tileset = map.getTileSets().getTileSet("tileset1");
TiledMapTile grassTile = tileset.getTile(4);
TiledMapTile rockTile = tileset.getTile(6);
Array<StaticTiledMapTile> playerTileArr = new Array<StaticTiledMapTile>();
playerTileArr.add((StaticTiledMapTile)tileset.getTile(7));
playerTileArr.add((StaticTiledMapTile)tileset.getTile(8));
Cell grass = new Cell();
grass.setTile(grassTile);
Cell player = new Cell();
player.setTile(new AnimatedTiledMapTile(0.1f, playerTileArr));
layer.setCell(0,0, grass); // <--- This works.
layer.setCell(0,1, player); // <--- When I try this, it causes
// a NullPointerException.
renderer = IsometricTiledMapRenderer(map, 1 / 30f);
...
Can someone help? I found an AnimatedTiledMapTile usage example for TideMapLoader but I know I'm using a " tiled map" (not a " tide map"). However.. someone can explain how I can make an animation on a specific tile?
Been by this a few time searching my self. But got it to work now.
Best guess is that your tileset don't have 7 or 8 tiles.
I got the following code to work:
TiledMapTileLayer layer = (TiledMapTileLayer) map.getLayers().get(0);
TiledMapTileSet tileset = map.getTileSets().getTileSet(0);
Array<StaticTiledMapTile> at = new Array<StaticTiledMapTile>();
if (tileset.getTile(0) != null) at.add((StaticTiledMapTile) tileset.getTile(0));
if (tileset.getTile(1) != null) at.add((StaticTiledMapTile) tileset.getTile(1));
if (tileset.getTile(2) != null) at.add((StaticTiledMapTile) tileset.getTile(2));
if (tileset.getTile(3) != null) at.add((StaticTiledMapTile) tileset.getTile(3));
layer.getCell(2, 2).setTile(new AnimatedTiledMapTile(0.3f, at));
Only getTile(1) and getTile(2) was != null - I only had 2 tiles. (my trouble was that getTile(0) wasnt the first tile.. getTile(1) was!)
