如何在active scene2d上实现简单的moveTo呢？？libgdx

import com.badlogic.gdx.ApplicationAdapter;
import com.badlogic.gdx.Gdx;
import com.badlogic.gdx.graphics.GL20;
import com.badlogic.gdx.scenes.scene2d.Actor;
import com.badlogic.gdx.scenes.scene2d.Stage;
import com.badlogic.gdx.scenes.scene2d.actions.Actions;
import com.badlogic.gdx.utils.viewport.ScreenViewport;

public class MoveToExample extends ApplicationAdapter {
    private Stage stage;
    private Actor actor;

    @Override
    public void create() {
        stage = new Stage(new ScreenViewport());
        Gdx.input.setInputProcessor(stage);

        // 创建一个Actor
        actor = new Actor();
        actor.setBounds(100, 100, 50, 50);
        actor.setColor(1, 0, 0, 1); // 设置颜色为红色

        // 将Actor添加到Stage
        stage.addActor(actor);

        // 创建移动动作
        actor.addAction(Actions.moveTo(300, 300, 2f)); // 移动到(300, 300)，持续2秒
    }

    @Override
    public void render() {
        Gdx.gl.glClearColor(0, 0, 0, 1);
        Gdl.gl.glClear(GL20.GL_COLOR_BUFFER_BIT);

        stage.act(Gdx.graphics.getDeltaTime());
        stage.draw();
    }

    @Override
    public void dispose() {
        stage.dispose();
    }
}
