SKWarpGeometryGrid is a grid based deformation what can be applied to nodes conforming to SKWarpable protocol. It defines normalised vertex positions for source and destination where source positions are un-warped geometry and destination warped geometry. Therefore, if destination vertex positions are not equal to source, the node will look deformed. Vertex positions Here is a …

Having a glow behind a sprite can give game a move lively environment. In this blog post I am going to present a way of adding a glow to SKSpriteNode using an instance of SKEffectNode. Node Tree First of all let's take a look on the node tree needed for achieving the end result. SKSpriteNode …
I was working on an upcoming game in SpriteKit only to discover that adding a simple gradient is not so straight-forward as one would expect. Therefore I created an extension to SKTexture. https://gist.github.com/laevandus/c38a8b9e958ef68c6730025f6b4cc7f4 This extension adds support for creating linear and radial gradients. Linear gradient can be drawn with an angle (in radians) although in …
