How can I get a small amount of liquid in my spriteKit application?
I want that liquid in a container, it will be sealed inside but I want it to be able to move around.<
I can suggest you "LiquidFun". Its very easy to Install and it is fun to play around with it. You can build Games like "Where's my Water?"... and others!
Here is a link to a tutorial from RayWenderlich: Click Me
I hope that this was helpful!
// But Note that this Version of LiquidFun is only for XCode 6.3
