将 TiledMap 加载到阶段 class ,libgdx

Question

我正在尝试将 tmx 地图加载到舞台 class 但是当我运行我的游戏屏幕不显示任何关于地图的信息，只显示角色，我认为问题是相机但不知道如何解决：

摘要屏幕：

public abstract class AbstractScreen extends Stage implements Screen{



protected AbstractScreen(){
    //Crea un punto de vista por defecto
    super(new StretchViewport(1024, 720));
}

/**
 * que deberá ser implementado por cada pantalla de nuestro juego. 
 * Este método se utiliza para añadir los actores a cada escena 
 * (LibGDX Scene2d).
 */
public abstract void buildStage();
public abstract void dispose();

public void render(float arg0) {
    /*
     * Limpiamos la Screen
     */
    //Con esto se define el color con el que se borrara el buffer al hacer un glClear()
    //Rgb y alpha(transparecia)
    Gdx.gl20.glClearColor(0, 0, 0, 1);
    // limpiar el buffer depth, el buffer secundario, 
    //para que no tenga cosas previamente dibujadas
    Gdx.gl.glClear(GL11.GL_COLOR_BUFFER_BIT);
    //buildStage();
    //llamada metodos stage
    super.act(Gdx.graphics.getDeltaTime());
    super.draw();
}

public void show() {
    // TODO Auto-generated method stub
    Gdx.input.setInputProcessor(this);
}


public void resize(int width, int height) {
    getViewport().update(width, height, true);

}


public void hide() {}

public void pause() {}

public void resume() {}

}

屏幕：

public class SpriteScreen extends AbstractScreen implements InputProcessor {

//private SpriteActor mActor;
private Player jugador;
private TouchPadPlayer touchpad;

private TiledMap map;
private static OrthogonalTiledMapRenderer renderer; 
private TiledMapTileLayer collision;

public SpriteScreen() {
    this.jugador = new Player(getWidth() / 2, getHeight() / 2);
    this.touchpad = new TouchPadPlayer();
    this.touchpad.setPosition(100, 100);

    this.map=new TmxMapLoader().load("assests/maps/example.tmx");
    collision = (TiledMapTileLayer)map.getLayers().get("Colisiones");
    renderer = new OrthogonalTiledMapRenderer(map, 1 / 16f);
}

@Override
public void buildStage() {
    // TODO Auto-generated method stub
    renderer.render();      
    Gdx.input.setInputProcessor(this);
    addActor(this.jugador);
    addActor(this.touchpad);

    this.getCamera().update();
    renderer.setView((OrthographicCamera) this.getCamera());
    renderer.render();


}

@Override
public void dispose() {
    // TODO Auto-generated method stub
    map.dispose();
    renderer.dispose();
}

首先，您的瓷砖尺寸是多少？你确定它是 16 x 16 像素吗？如果是这种情况，那么在 AbstractScreen 的调整大小方法中，您需要将相机调整为：

 public void resize(int width, int height) {
    getViewport().update(width, height, true);
    getViewport().getcamera().viewportWidth = YourScreenWidth / 16f;
    getViewport().getcamera().viewportHeight = YourScreenHeight / 16f;
    //set the camera to start from 0,0 and not from the center of the screen
    getViewport().getcamera().setToOrtho(false,                                            
                                        getViewport().getcamera().viewportWidth / 2f,
                                        getViewport().getcamera().viewportHeight/ 2f);

   getViewport().getcamera().update();
 }

这应该会在整个屏幕上显示您的地图。基本上，对于平铺地图，您无法以编程方式调整它们的大小，因为没有 setSize、setWidth 等方法，所以诀窍是使用相机和平铺大小来正确显示它们。

您必须在 'Screen' 的 render() 方法而不是 buildStage() 方法中调用 renderer.render();。
