Trying to get a bunch of images to show in succession when touching screen on Swift

Question

I put the different images to show in succession in the assets.xcassets folder as shooter, shooter1, shooter2 and so on but whenever i touch the screen the animation/image shown in the view doesn't change?

Here is my code:

 import UIKit
 import SpriteKit

 class ShooterScene: SKScene
 {

     var score = 0
     var enemyCount = 10
     var shooterAnimation = [SKTexture]()

     override func didMove(to view: SKView)
     {
         self.initShooterScene()
     }

     func initShooterScene()
     {
         let shooterAtlas = SKTextureAtlas(named: "shooter") // referencing shooter.atlas
         for index in 1...shooterAtlas.textureNames.count
         {
             let imgName = "shooter\(index)"
             shooterAnimation += [shooterAtlas.textureNamed(imgName)]
         }
     }

     //Animate the shooter

     override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
         if let shooterNode  = self.childNode(withName: "shooterNode") as? SKSpriteNode
         {
             let animation = SKAction.animate(with: shooterAnimation, timePerFrame: 0.1)
             shooterNode.run(animation)
         }
      }



  }

The sprite node that I use in the view has the name shooterNode but the image doesn't seem to change at all. Any help would be great

Did you set your shooter node's name property to "shooterNode"? After setting that. Your code worked for me. — KissTheCoder, Jan 23 '20 at 01:24
If you mean the sprite property yes I've done that. It still doesn't work. I'm wondering if it's the way I first put the sprite into the view? I dragged the image directly from the shooter.atlas folder because I don't see any other option of putting the sprite into the view? — Richard Desouza, Jan 23 '20 at 21:40
I also get this output from the console. Please see the above edit — Richard Desouza, Jan 23 '20 at 22:49

Here's your code modified. It works for me. Without more code, I don't know how you are setting up your shooter node so I can't replicate your issue.

class ShooterScene: SKScene {

    var textures = [SKTexture]()

    //Also serves as the name of the texture the node uses.
    let NODE_NAME:String = "shooter"

    override init(size: CGSize) {
        super.init(size: size)
        //Better the setup scene in intializer, because didMove(to view) is called multiple times.
        //You only want to call the setup method once.
        self.setup()
    }

    required init?(coder aDecoder: NSCoder) {
        fatalError("init(coder:) has not been implemented")
    }


    func setup() {

       //Node setup
       let shooterNode = SKSpriteNode(imageNamed: NODE_NAME)
       shooterNode.position = CGPoint(x: self.frame.midX, y: self.frame.midY)
       shooterNode.name = NODE_NAME
       addChild(shooterNode)

       //Create animation collection
       let atlas = SKTextureAtlas(named: NODE_NAME)
        //Arrays start at index zero so we need to subtract 1 from the total textures count
        let upperBound = atlas.textureNames.count - 1
        for index in 1...upperBound {
            let textureName = "\(NODE_NAME)\(index)"
            textures += [atlas.textureNamed(textureName)]
        }
    }

    //Animate the shooter when screen pressed.
    override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {

        guard let shooterNode = self.childNode(withName: NODE_NAME) as? SKSpriteNode else { return }
        //For animations that are around 60 Frames per second
        let FPS:Double = 1/60
        let animation = SKAction.animate(with: self.textures, timePerFrame: FPS)
        shooterNode.run(animation)
    }



 }

I've posted an edit of what my xcode looks like on the shooterscene.sks. Is there anything I'm doing wrong from what you can see? — Richard Desouza, Jan 26 '20 at 15:16
