問題描述

在 LibGDX 中，我想為我的游戲制作文本動畫.因此，我希望我的標(biāo)簽隨著時間的推移而變大.但是如果我使用 scaleTo() 方法，什么都不會發(fā)生，而像 moveTo() 這樣的其他動作可以正常工作.

In LibGDX, I want to make a text animation for my game. Therefore, I want that my labels gets larger with time. But if I use the scaleTo() method, nothing happens whereas other Actions like moveTo() work fine.

label1 = new Label("Test text", new Label.LabelStyle(font, Color.BLACK));
label2.addAction(Actions.parallel(Actions.moveTo(500, 300, 2.0f),Actions.scaleTo(0.1f, 0.1f,2.0f)));

label2 = new Label("Test text 2", new Label.LabelStyle(font, Color.BLACK));
label2.addAction(Actions.parallel(Actions.moveTo(500, 300, 2.0f),Actions.scaleTo(0.1f, 0.1f,2.0f)));

stage.addActor(label1);
stage.addActor(label2);

如何讓我的標(biāo)簽按比例縮放?提前謝謝！

How can I make my labels scale? Thank you in advance!

推薦答案

出于性能原因，大多數(shù)scene2d.ui組默認(rèn)將transform設(shè)置為false.

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

如果你想縮放，你可以使用 Container 來設(shè)置單個小部件的大小和對齊方式.

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

private Container<Label> container;

@Override
public void create() {
    stage=new Stage();

    Label label1 = new Label("Test text", new Label.LabelStyle(font, Color.BLACK));

    container=new Container<Label>(label1);
    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();
}

在容器而不是標(biāo)簽上添加您的操作.

Add your Action on container instead of Label.

container.addAction(Actions.parallel(Actions.moveTo(500, 300, 2.0f),Actions.scaleTo(0.1f, 0.1f,2.0f)));
