Question

当我在桌面上运行游戏时工作正常，但是当我在我的Android设备中运行它时，图像看起来有一半，当我使用PLAY按钮游戏关闭时，任何人都可以帮助我吗？谢谢。

public class GameScreen extends AbstractScreen {

    private Viewport viewport;
    private Camera camera;

            puntuacionMaxima = preferencias.getInteger("puntuacionMaxima");
            music =Gdx.audio.newMusic(Gdx.files.internal("bgmusic.mp3"));
            music.play();
            music.setVolume((float) 0.3);

        texture.dispose();

    }

    @Override
    public void dispose(){

    }

    public void resize(int width, int height){      
        float widthImage = texture.getWidth();
        float heightImage = texture.getHeight();
        float r = heightImage / widthImage;
        if(heightImage > height) { 
            heightImage = height;

            heightImage = widthImage * r;
        }
        escala = width / widthImage; 

        if(Gdx.app.getType()== ApplicationType.Android)
        viewport.update(width, height);

    }

}

首先，使用正交相机。

camera=new OrthographicCamera(800,480);
camera.position.set(800/2f,480/2f,0);
viewport=new FitViewport(800,480,camera);

现在0,0位于屏幕的左下角。

在批处理之前。不要忘记设置投影矩阵

batch.setProjectionMatrix(camera.combined);
batch.begin();

batch.end();

Viewport的Android问题
