我的LibGDX游戏有一个带有徽标和一些按钮的开始屏幕。我无法弄清楚如何以固定的比例缩放徽标,以免扭曲它。

这就是代码:

public StartScreen(int lastScore, InputListener inputListener) {
    super();
    this.listener = inputListener;
    stage = new Stage();
    Gdx.input.setInputProcessor(stage);

    Table table = new Table();
    table.setFillParent(true);
    table.setBackground(new TextureRegionDrawable(new TextureRegion(new Texture(Gdx.files.internal("background.png")))));

    Image imageLogo = new Image();
    imageLogo.setDrawable(new TextureRegionDrawable(new TextureRegion(new Texture(Gdx.files.internal("title.png")))));

    // Here's the problem, the image is not scaled correctly...
    table.add(imageLogo).center().colspan(2);
    table.row();

    // Some Buttons
    table.add(button1).colspan(2).padBottom(30);
    table.row();
    table.add(button2).padBottom(30);
    table.add(button3).padBottom(30);
    table.row();
    table.add(button4).colspan(2);

    stage.addActor(table);

    //table.debug();
}

我发现你可以将它用于图像 - 工作正常!

imageLogo.setScaling(Scaling.fit);

您可以按如下方式缩放图像:

Image imageLogo = new Image();
imageLogo.setDrawable(new TextureRegionDrawable(
        new TextureRegion(new Texture(Gdx.files.internal("title.png")))));

// 0.9f scales to 90% of the original height and width
final float heightScaleFactor = 0.9f;
final float widthScaleFactor = 0.9f;

imageLogo.setHeight(imageLogo.getHeight() * heightScaleFactor);
imageLogo.setWidth(imageLogo.getWidth() * widthScaleFactor);
