Libgdx window add alpha action change the background actor alpha

现象:

      Stage中包括一个Window,一个Actor,Window中加入alpha action后,Actor也随之消失;Actor加入alpha action后,不起作用。

解决:

      重写draw方法,加入batch.setColor(getColor().r, getColor().g, getColor().b, getColor().a);

import com.badlogic.gdx.graphics.g2d.Batch;import com.badlogic.gdx.scenes.scene2d.Actor;import com.secondegg.reversi.util.Assets;/** * * @author cuizhf */public class Table extends Actor {        public Table() {    }        @Override    public void act (float delta) {        super.act(delta);    }        @Override    public void draw (Batch batch, float parentAlpha) {        batch.setColor(getColor().r, getColor().g, getColor().b, getColor().a);            batch.draw(Assets.instance.table.tableh, 0, 0);        batch.draw(Assets.instance.table.tablen, 100, 0);    }}
