How Do I Blur a Scene in SpriteKit?

Question

How would I add a gaussian blur to all nodes (there\'s no fixed number of nodes) in an SKScene in SpriteKit? A label will be added on top of the scene later, this will be m

Answer 1

Swift 4:

add this to your gameScene if you want to blur everything in the scene:

let  blur = CIFilter(name:"CIGaussianBlur",withInputParameters: ["inputRadius": 10.0])
        self.filter = blur
        self.shouldRasterize = true
        self.shouldEnableEffects = false

change self.shouldEnableEffects = true when you want to use it.
