Fill SKScene background with tiled image

I found the method to fill background with pattern image

class SceneTitle : SKScene {
     override func didMoveToView(view: SKView) {
          let Img: UIImage = UIImage(named: "brick.png")!
          self.backgroundColor = UIColor(patternImage: Img)
     }
}

It seems Loading UIImage works fine , but background color was not changed.

Hi polig,

Pattern images are not supported via UIColor in SpriteKit. You can achieve pattern color effects by using an SKShader on a sprite node. By scaling and offsetting the passed in texture coordinates you can get repeating patterns. The editor supports live editing of a shader in a .fsh file, so you can experiment right in Xcode.

Have a look at https://developer.apple.com/library/ios/documentation/SpriteKit/Reference/SKShader_Ref/index.html

Hi greven

it seems omnipotent but difficult.

I will look SKShader up.

Thks!

Hi Polig,

Shaders are initially a bit daunting but once you get used to them you'll love them. Have a look at https://www.shadertoy.com if you want to see what can be done using just a fragment shader.

Please do file an enhancement request radar if using pattern UIColors is important to you. It is a way for you to 'vote' for features you'd like to see.

Cheers
