Question

我想要做的是为我的世界设置一个虚拟大小，并在不改变纵横比的情况下尽可能地在屏幕上缩放该世界，FitViewport 似乎是最佳选择。这就是我在舞台上初始化视口的方式。

public class PlayStage extends Stage{

public static final int       WIDTH = 480;
public static final int       HEIGHT = 800;

private final Vector2   gravity = new Vector2(0.f, -9.8f);
private World           physWorld;

public PlayStage(){
    super();
    OrthographicCamera camera = new OrthographicCamera();
    camera.setToOrtho(false, WIDTH, HEIGHT);
    setViewport(new FitViewport(WIDTH, HEIGHT, camera));

    physWorld = new World(gravity, false);
    Gdx.input.setInputProcessor(this);

    Ball ball = new Ball(physWorld);
    setKeyboardFocus(ball);
    addActor(ball);
}

@Override
public void draw() {
    super.draw();
}

@Override
public void act(float delta) {
    super.act(delta);
    physWorld.step(delta, 10, 5);
}

@Override
public void dispose() {
    super.dispose();
    physWorld.dispose();
}}

这是精灵在渲染时的样子（在 x 坐标上缩放太多）。我的演员也没有着陆事件。

Answer 1

我自己解决了，我所要做的就是像这样在创建后更新视口getViewport().update(Gdx.graphics.getWidth(), Gdx.graphics.getHeight());

Answer 2

您需要更新舞台视口。最好通过调整大小方法调整视口的大小。

@Override
public void resize(int width, int height) {
    stage.getViewport().update(width,height);
    //stage.getViewport().update(width,height,true); // -> If you want camera to be at centre.
}

libGDX - 适合视口不能很好地缩放舞台

libGDX - FitViewport doesnt scale well the stage

java
