Libgdx Choosing correct textures based on DPI?

How to implement a system which takes the best texture based on dpi from a set like in android SDK, because LibGDX is platform independent, and can't use the already existent one?

Solution

  • May be my solution is not the best but I used it in real project and it worked.

    In your Game class use Gdx.graphics.getDensity() method to choose appropriate folder, store its name in public field and load your assets:

    public class MyGame extends Game {

public static String folder;
private AssetManager assets;

@Override
public void create() {
   if (Gdx.graphics.getDensity < 1) {
      folder = "lowDpiImages/";
   } else {
      folder = "highDpiImages/";
   }
   ...
   assets = new AssetManager();
   assets.load(folder + "image.png", Texture.class, paramsNearest);
   ...
}

    Then in you other classes use folder name to get assets from AssetManager:

    assets.get(MyGame.folder + "image.png", Texture.class);

    You can write more sophisticated folder choosing algorithm of cause ;-)
