c++ - Cocos2d-x 4.0 Lens3D和Waves3D动画

Question

我用下面的代码制作了像动画一样的水作为背景图像

    auto background = Sprite::create(TEX_MM_BG);
    background->setPosition(Vec2(SW*0.5f, SH*0.5f));

    auto nodeGrid = NodeGrid::create();
    nodeGrid->addChild(background);
    this->addChild(nodeGrid, 0);


    ActionInterval* lens = Lens3D::create(10, Size(32, 24), Vec2(100, 180), 150);
    ActionInterval* waves = Waves3D::create(10, Size(15, 10), 18, 15);

    nodeGrid->runAction(RepeatForever::create(Sequence::create(waves,lens, NULL)));

动画外观不错。但是它停止10秒，然后播放10秒，然后再次停止10秒...重复。如何避免在中间停下来？

Answer 1

它不会停止，而是先应用波浪效果，再应用透镜效果。在应用镜头效果时，波的动画停止。

正确的编码方式是使用Spawn:

 ActionInterval* lens = Lens3D::create(10, Size(32, 24), Vec2(100, 180), 150);
 ActionInterval* waves = Waves3D::create(10, Size(15, 10), 18, 15);
 // Spawn will run both effects at the same time.
 auto lensWaveSpawn = Spawn::createWithTwoActions(lens, waves);

 auto seq = Sequence::create(lensWaveSpawn, nullptr);
 nodeGrid->runAction(RepeatForever::create(seq));
