I’ve put together a physical water simulation for SpriteKit for a game that I’m working on, which I’ve made open source.
I know there’s quite a few SpriteKit users on the forums, so thought it might be useful.
There’s a gif on the github repo so you can check it out without having to go to the bother of downloading and building the code. I’ve also included a little settings pane on the demo project so that you can tweak different properties of the simulation to see how the water reacts.
Enjoy!
