淡入淡出行动

Question

我有SplashScreen，我加载资源并显示图像

一切运作良好，但fadeIn Action虽然fadeOut有效但无法正常工作

这是我的代码：

public void show() {
    stage = new Stage();
    Texture splashTexture = new Texture(Gdx.files.internal("splash.png"));
    splash = new Image(splashTexture);
    splash.setPosition(Constants.WIDTH/2 - splash.getWidth()/2, Constants.HEIGHT/2 - splash.getHeight()/2);
    stage.addActor(splash);
    splash.getColor().a = 0;
    SequenceAction sequenceAction = new SequenceAction(Actions.fadeIn(2.0f), Actions.delay(2.0f), 

Actions.fadeOut(2.0f), Actions.run(new Runnable() { 
    @Override public void run() { gameMain.setScreen(new MenuScreen(gameMain, null, true)); } }));
    splash.addAction(Actions.parallel(Actions.run(new Runnable() { 
    @Override public void run() { Assets.load(); 
    } }), sequenceAction)); }

Answer 1

尝试在fadeIn操作之前使用Actions.fadeOut(0f)

SequenceAction sequenceAction = new SequenceAction(Actions.fadeOut(0f),Actions.fadeIn(2.0f), ...);

或

而splash.getColor().a = 0;使用splash.setColor(1,1,1,0);
