I can't get SKCropNode to cooperate. I've played with this for HOURS I've copied verbatim hackingwithswifts guide and the only difference being my image and it will not work. So then I dumbed it down for myself with the code below and it still doesn't work.

I've tried the guide directly from hacking with swift and it didn't work. I copied code directly from apple documentation that also didn't work. I've wasted wayyyy too much time on the simple task of cropping an image.

import SpriteKit
import GameplayKit
import UIKit
class ProcGenPlanet: SKScene{
//Background
//let background = SKSpriteNode()
var square = SKSpriteNode()
override func didMove(to view: SKView) {
square = SKSpriteNode(imageNamed: "redSquare")
square.size = CGSize(width: 1000, height: 1000)
square.position = CGPoint(x: self.frame.size.width/2, y: self.frame.size.height/2)
let mask = SKSpriteNode(color: SKColor.black, size: CGSize(width: 100, height: 100))
let cropNode = SKCropNode()
cropNode.maskNode = mask
cropNode.position = CGPoint(x: self.frame.size.width/2, y: self.frame.size.height/2)
cropNode.addChild(square)
}
}

I am creating 1000x1000 red square. The whole image is red. Then I am trying to crop it to 100x100 with the following code but instead NOTHING shows up.

    1) delete all lines where you are setting `position`, 2) your mask should contain transparent (allows through) and non-transparent (filters) pixels, and 3) you need to add cropNode to the scene. – 0x141E Aug 03 '19 at 09:17
  • I ended up scratching all this code and copy and pasting the hacking with swift example and it worked. But I'm sure it wasn't working because I somehow didnt add cropNode to scene so I'd mark this as the right answer if it weren't a comment. – ItsSgtMarv Aug 07 '19 at 02:39
