如何在 LibGdx 中缩放标签

2022-01-12 00:00:00 android java libgdx

我正在尝试为我的游戏编写 HUD，但我不知道如何正确缩放标签我正在使用此代码:

i am trying to code a HUD for my game but i cannot figure out how to scale a Label properly I am using this code:

Label hpLabel = new Label("HP: ",new Label.LabelStyle(new BitmapFont(),Color.BROWN));
    table.add(hpLabel);
    viewport = new FitViewport(Gdx.graphics.getWidth()/ FacultyWars.PPM, Gdx.graphics.getHeight()/ FacultyWars.PPM, cam);
    stage = new Stage(viewport, batch);
    stage.addActor(table);
//other ellements added after this

HP 标签在屏幕上很大.我尝试在标签和桌子上使用 setScale 无济于事.任何帮助表示赞赏！谢谢

The HP tag is enormous on the screen. I tried using setScale on the label and on the table to no avail. Any help is appreciated! Thanks

推荐答案

只需将标签添加到组，然后将比例应用于组.

Simply add the Label to a Group then apply the scale to the group.

    Label label = new Label("hello", skin);
    Group group = new Group();
    group.addActor(label);
    group.setScale(2f, 2f);

我只在动画中缩放带有标签的组，在动画结束时缩放为 1.不应缩放字体，因为它看起来像素化.比如一个简单的放大缩小动画:

I only scale Groups with Labels in animations where at the end of the animation the scale is 1. One should not scale fonts, because it looks pixelated. For example, a simple scale up scale down animation:

group.addAction(Actions.sequence(Actions.scaleTo(2f, 2f, 1f), Actions.scaleTo(1f, 1f, 1f)));
