Swift / SpriteKit：如何创建水滴效果？

Question

i wonder how the following effect could be made in Swift (SpriteKit).

I think about adding some ShapeNodes and fill them with the background image with -yscale 1.

But i think this effect was made somehow different, because the background image isn't just mirrored horizontally - it also has some graphics effects on it (it is mirrored in the shape the water pearl has and so on).

Was it done with a ShaderNode?

Does someone has an idea how i could create a same effect in SpriteKit - like water pearls which looks like they are on the "camera" and they mirror the background "waterpearl like"?

Thank you.

嗯，您可以创建一堆水图像，并将它们随机显示在屏幕上某个z位置处，但是我认为这种效果是在另一个程序（如unity或类似的程序）中实现的，最好的选择是创建透明的水滴作为图像并将它们随机显示在屏幕上。
