Libgdx - 如何让对话淡出而不是整个舞台？

When I show a Dialog with

当我显示一个Dialog时

someDialog.show(someStage);

The dialog show with default FadeIn action. And the stage fade in too. So it make my background fade along with the stage.

该对话框显示默认的FadeIn操作。舞台也渐渐淡出。因此它使我的背景随着舞台逐渐消失。

How can I prevent this to happen?

我怎样才能防止这种情况发生?

编辑:这里是我的示例代码:

In Screen show method:

在屏幕显示方法中:

Texture bg = new Texture(Gdx.files.internal(src));
stage = new Stage(game.getViewport(), batch);
stage.addActor(someDialog) //just normal dialog

render code:

@Override
    public void render(float delta) {
        super.render(delta);
        getBatch().begin();
        getBatch().draw(backgroundTexture, 0, 0, width, height);
        getBatch().end();
        getStage().act(delta);
        getStage().draw();
        time += delta;
    }

I show the dialog when some event trigger:

我在某个事件触发时显示对话框:

   dialog.show(getStage());

I have tried to put null as second parameter to the show method

我试图将null作为第二个参数放到show方法中

dialog.show(getStage(), null);

and make both stage and dialog not fade in but a want to keep the effect for only dialog or at least not the background.

并且使得舞台和对话框都不会淡入但是想要仅保留对话框的效果,或者至少不保留背景效果。

Stage doesn't clean up the SpriteBatch's color when it's done, so when the loop comes back around, the last-used color is still applied to the sprite batch. In your case, the last used color happens to be the dialog's color.

舞台不会在完成后清理SpriteBatch的颜色,因此当循环返回时,最后使用的颜色仍然应用于精灵批处理。在您的情况下,最后使用的颜色恰好是对话框的颜色。

To fix this, add getBatch().setColor(Color.WHITE); before your getBatch().draw(backgroundTexture, 0, 0, width, height); line.

要解决此问题,请添加getBatch()。setColor(Color.WHITE);在你的getBatch()。draw之前(backgroundTexture,0,0,width,height);线。

And I don't think your whole stage is fading. Right now, your background texture has nothing to do with the stage, except that they're both sharing use of the SpriteBatch.

我不认为你的整个舞台正在消退。现在,你的背景纹理与舞台无关,只是它们都共享使用SpriteBatch。
