Need to make parallax effect in the game with LibGDX and tiled map. Background should move with different speed then foreground. In the docs https://github.com/libgdx/libgdx/wiki/Tile-maps said:
By rendering each layer separately and modifying the view for every layer, you can also achieve a parallax effect.
Current implementation: with PlayScreenVariantOne all works but background moving with same speed like foreground
public class PlayScreenVariantOne implements Screen {
private TextureAtlas atlas;
private OrthographicCamera gameCam;
private Viewport viewport;
private TmxMapLoader mapLoader;
private TiledMap map;
private OrthogonalTiledMapRenderer renderer;
...
// ...
// ... bla-bla-bla...
// ...
@Override
public void render(float delta) {
update(delta);
Gdx.gl.glClearColor(0, 0, 0, 1);
Gdx.gl.glClear(GL20.GL_COLOR_BUFFER_BIT);
renderer.setView(gameCam);
renderer.render();
game.batch.setProjectionMatrix(gameCam.combined);
game.batch.begin();
player.draw(game.batch);
game.batch.end();
hud.stage.draw();
}
}
Parallax implementation: with PlayScreenVariantTwo foreground and background rendered with same speed. Parallax effect does not work! :*(
public class PlayScreenVariantTwo implements Screen {
private TextureAtlas atlas;
private OrthographicCamera gameCam;
private Viewport viewport;
private TmxMapLoader mapLoader;
private TiledMap map;
private OrthogonalTiledMapRenderer renderer;
...
// ...
// ... bla-bla-bla...
// ...
@Override
public void render(float delta) {
update(delta);
Gdx.gl.glClearColor(0, 0, 0, 1);
Gdx.gl.glClear(GL20.GL_COLOR_BUFFER_BIT);
int[] backgroundLayers = { 7 };
int[] ground = { 9 };
renderer.setView(gameCam.combined, (gameCam.position.x - gameCam.viewportWidth / 2 - 2), gameCam.position.y - gameCam.viewportHeight / 2, gameCam.viewportWidth, gameCam.viewportHeight);
renderer.render(backgroundLayers);
renderer.setView(gameCam.combined, (gameCam.position.x - gameCam.viewportWidth / 2) / 10, gameCam.position.y - gameCam.viewportHeight / 2, gameCam.viewportWidth * 10, gameCam.viewportHeight);
renderer.render(ground);
game.batch.setProjectionMatrix(gameCam.combined);
game.batch.begin();
player.draw(game.batch);
game.batch.end();
hud.stage.draw();
}
}
