LibGDX缩放滑块，如何? [英] LibGDX scale a slider, HOW?

问题描述

如何缩放LibGDX中的滑块?

How can I scale a slider in LibGDX?

我正在尝试通过以下方式缩放滑块:

Im trying to scale a slider with:

slider.scale(10); (例如)

slider.scale(10); (for example)

但是当我尝试无法与滑块互动时，导致我认为滑块IST已缩放但呈现正常.我用slider.draw(batch，1);

but when I try that i cant interact with the slider that leads to me thinking that the slider ist scaled but rendered normally. I render it with slider.draw(batch, 1);

有人知道吗?

推荐答案

出于性能原因，大多数scene2d.ui组默认将transform设置为false.

For performance reason most scene2d.ui groups have transform set to false by default.

如果要缩放，可以使用Container(容器)，它对于设置单个小部件的大小和对齐方式很有用.

If you want to scale you can use Container which is useful for setting the size and alignment of a single widget.

@Override
public void create() {
    stage=new Stage();
    Skin skin=new Skin(Gdx.files.internal("skin/uiskin.json"));

    Slider slider=new Slider(0,100,1,false,skin);

    Container<Slider> container=new Container<Slider>(slider);
    container.setTransform(true);   // for enabling scaling and rotation
    container.size(100, 60);
    container.setOrigin(container.getWidth() / 2, container.getHeight() / 2);
    container.setPosition(100,200);
    container.setScale(3);  //scale according to your requirement

    stage.addActor(container);
}

@Override
public void render() {
    super.render();

    Gdx.gl.glClearColor(1,1,1,1);
    gl.glClear(GL20.GL_COLOR_BUFFER_BIT);

    stage.draw();
    stage.act();
}
