Type 'UIImage' has no member 'radialGradientImage'

I'm trying to use a color gradient for the background of a scene in my sprite kit game. So it looks similar to this:



enter image description here



I need help solving the following error:




Type 'UIImage' has no member 'radialGradientImage'




The code:



import UIKit

import SpriteKit

import StoreKit

import GameKit

import AVFoundation

import SpriteKit.SKTexture



class Start: SKScene {

    let color1 = UIColor(red: 255/255, green: 153/255, blue: 102/255, alpha: 1)

    let color2 = UIColor(red: 255/255, green: 204/255, blue: 153/255, alpha: 1)



    //Error ->

    let backgroundImg = UIImage.radialGradientImage(size: frame.size, outerColor: color1, innerColor: color2)



    //



    let backgroundTexture = SKTexture(image: backgroundImg)

    let background = SKSpriteNode(texture: backgroundTexture)



    override func didMove(to view: SKView) {

        //Background

        background.position = CGPoint(x: self.size.width/2, y: self.size.height/2)

        addChild(background)

    }



    static func radialGradientImage(size: CGSize, outerColor: UIColor, innerColor: UIColor) -> UIImage

    {

        let colorSpace = CGColorSpaceCreateDeviceRGB()

        let gradient = CGGradient(colorsSpace: colorSpace, colors: [outerColor.cgColor, innerColor.cgColor] as CFArray, locations: [1.0, 0.0])

        let center = CGPoint(x: size.width / 2.0, y: size.height / 2.0)



        UIGraphicsBeginImageContextWithOptions(size, false, UIScreen.main.scale)

        let imageContext = UIGraphicsGetCurrentContext()



        imageContext!.drawRadialGradient(gradient!, startCenter: center, startRadius: 0.0, endCenter: center, endRadius: size.width / 2.0, options: CGGradientDrawingOptions.drawsAfterEndLocation)



        let image = UIGraphicsGetImageFromCurrentImageContext()

        UIGraphicsEndImageContext()

radialGradientImage is a static method of your Start class, not the UIImage class.



You want:



let backgroundImg = Start.radialGradientImage(size: frame.size, outerColor: color1, innerColor: color2)


But that is going to fail with more errors because you can't access frame, color1, or color2 there.



You need to change let to lazy var:



lazy var backgroundImg = Start.radialGradientImage(size: frame.size, outerColor: color1, innerColor: color2)

  • Thanks that worked well. Is there also a possibility to use a vertical gradient instead of a radial gradient (like the gradient from the screenshot in my question)?
