java libGDX：更改滚动窗格的滚动位置

Question

In我的代码y滚动位置（以像素为单位）位于滚动窗格的顶部：

    stage = new Stage(new StretchViewport(480, 800));
    Image map = new Image(new Texture(Gdx.files.internal("assets-levels/map.png")));
    scrollpane = new ScrollPane(map, new ScrollPaneStyle());
    scrollpane.setFillParent(true);
    stage.addActor(scrollpane);

    Gdx.input.setInputProcessor(stage);

如何更改滚动窗格底部的y滚动位置

Answer 1

1. 创建一个名为MyScrollPane的类，该类将从ScrollPane复制
2. 添加这一行myScrollpane.amountY = map.getHeight();
