I added some tiles to some object layers in my tiled map and now I want to draw them in game. I tried to render everything with
mapRender.render();
but the tiles doesn't show up. Then I tried to render just one object layer and all of its objects with
mapRenderer.renderObjects(tiledMap.getLayers().get(0));
but it wasn't working.
Ingame:
Tiled:
Could someone please tell me how to make the tiles show up? Thank you very much!
All current implementations of TiledMapRenderer, such as BatchTiledMapRenderer, do not have the functionality to render any MapObject. You'll have to create your own implementation of TiledMapRenderer. This should get you started:
public class TextureMapObjectRenderer extends OrthogonalTiledMapRenderer {
public TextureMapObjectRenderer(TiledMap map) {
super(map);
}
public TextureMapObjectRenderer(TiledMap map, Batch batch) {
super(map, batch);
}
public TextureMapObjectRenderer(TiledMap map, float unitScale) {
super(map, unitScale);
}
public TextureMapObjectRenderer(TiledMap map, float unitScale, Batch batch) {
super(map, unitScale, batch);
}
@Override
public void renderObject(MapObject object) {
if (object instanceof TextureMapObject) {
TextureMapObject textureObject = (TextureMapObject) object;
batch.draw(
textureObject.getTextureRegion(),
textureObject.getX(),
textureObject.getY()
);
}
}
}
I would also recommend against using Tile Objects to render sprites in-game, as they're more commonly used for Tiled purposes and identifying entities that you want to spawn in-game. This video explains what I mean here.
This depends on the type of game, however. This is an example of using an Object Layer with Tile Objects for creating levels in a Breakout game; it makes it very easy for Box2D bodies to be created and the bricks to be drawn:
getScaleX() and getScaleY() which may be of use to you, but I am not entirely sure of their reliability.

textureObject.getProperties() for width and height properties? As far as I am aware, libGDX does deserialize this data.

Please consider that the previous answer is not complete.
If you render object with the 3 param batch.draw(...), the TextureMapObject would be rendered without the provided in the TileMap scale and rotation. I suggest using a more accurate
batch.draw (TextureRegion region, float x, float y, float originX, float originY, float width, float height,
float scaleX, float scaleY, float rotation);
in my kotlin implementation it looks like this
override fun renderObject(obj: MapObject) {
if (obj is TextureMapObject) {
batch.draw(
obj.textureRegion,
obj.x,
obj.y,
obj.originX,
obj.originY,
obj.textureRegion.regionWidth.toFloat(),
obj.textureRegion.regionHeight.toFloat(),
obj.scaleX,
obj.scaleY,
obj.rotation)
}
}
I made this code and it works for me:
import com.badlogic.gdx.Gdx;
import com.badlogic.gdx.graphics.g2d.Batch;
import com.badlogic.gdx.maps.MapObject;
import com.badlogic.gdx.maps.objects.TextureMapObject;
import com.badlogic.gdx.maps.tiled.TiledMap;
import com.badlogic.gdx.maps.tiled.renderers.OrthogonalTiledMapRenderer;
public class TextureMapObjectRenderer extends OrthogonalTiledMapRenderer {
public TextureMapObjectRenderer(TiledMap map) {
super(map);
}
public TextureMapObjectRenderer(TiledMap map, Batch batch) {
super(map, batch);
}
public TextureMapObjectRenderer(TiledMap map, float unitScale) {
super(map, unitScale);
}
public TextureMapObjectRenderer(TiledMap map, float unitScale, Batch batch) {
super(map, unitScale, batch);
}
@Override
public void renderObject(MapObject object) {
if (object instanceof TextureMapObject) {
Gdx.app.debug("TextureMapObjectRenderer", "renderObject");
TextureMapObject textureObject = (TextureMapObject) object;
batch.draw(
textureObject.getTextureRegion(),
textureObject.getX()* unitScale,
textureObject.getY()* unitScale,
textureObject.getOriginX()* unitScale,
textureObject.getOriginY()* unitScale,
textureObject.getTextureRegion().getRegionWidth()* unitScale,
textureObject.getTextureRegion().getRegionHeight()* unitScale,
textureObject.getScaleX(),
textureObject.getScaleY(),
textureObject.getRotation()
);
}
}
}
You must use the unitScale to consider your map
