问题描述
在 LibGDX 中,我想为我的游戏制作文本动画.因此,我希望我的标签随着时间的推移而变大.但是如果我使用 scaleTo()
方法,什么都不会发生,而像 moveTo()
这样的其他动作可以正常工作.
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);
如何让我的标签按比例缩放?提前谢谢!
How can I make my labels scale? Thank you in advance!
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.

如果你想缩放,你可以使用 Container 来设置单个小部件的大小和对齐方式.
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();
}
在容器而不是标签上添加您的操作.
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)));
