Scope

[elysha]

Hi, I'm doing a lesson in the utub, there's a way to move to another level, but when I'm on it, all the images are missing, I think it's a size thing, how can we fix that?

This is GameScene.swift:

struct PhysicsCategory {
static let En: UInt32 = 1
static let Bullet: UInt32 = 2
static let Player: UInt32 = 3
}
class GameScene: SKScene, SKPhysicsContactDelegate {

var Player = SKSpriteNode(imageNamed: "Image")

var score = Int()

var Scorelbl = UILabel()

override func didMoveToView(view: SKView) {

physicsWorld.contactDelegate = self
self.scene?.size = CGSize(width: self.frame.size.width, height: self.frame.size.height)

Player.position = CGPointMake(self.size.width / 2, self.size.height / 5)

Player.physicsBody = SKPhysicsBody(rectangleOfSize: Player.size)

Player.physicsBody?.affectedByGravity = false

Player.physicsBody?.categoryBitMask = PhysicsCategory.Player

Player.physicsBody?.contactTestBitMask = PhysicsCategory.En

Player.physicsBody?.dynamic = false
var Timer = NSTimer.scheduledTimerWithTimeInterval(0.2, target: self, selector: Selector("Spaw"), userInfo: nil, repeats: true)

var EnTimer = NSTimer.scheduledTimerWithTimeInterval(1.0, target: self, selector: Selector("SpawEn"), userInfo: nil, repeats: true)

self.addChild(Player)

Scorelbl.text = "(score)"

Scorelbl = UILabel(frame: CGRect(x: 0, y: 0, width: 100, height: 20))

Scorelbl.backgroundColor = UIColor.whiteColor()

Scorelbl.textColor = UIColor.blackColor()

self.view?.addSubview(Scorelbl)

}

func didBeginContact(contact: SKPhysicsContact) {

var firstBody : SKPhysicsBody = contact.bodyA

var secondBody: SKPhysicsBody = contact.bodyB

if ((firstBody.categoryBitMask == PhysicsCategory.En) && (secondBody.categoryBitMask == PhysicsCategory.Bullet) || (firstBody.categoryBitMask == PhysicsCategory.Bullet) && (secondBody.categoryBitMask == PhysicsCategory.En)){

collisionBullet(firstBody.node as! SKSpriteNode, Bullet: secondBody.node as! SKSpriteNode)

}

else if ((firstBody.categoryBitMask == PhysicsCategory.En) && (secondBody.categoryBitMask == PhysicsCategory.Player) || (firstBody.categoryBitMask == PhysicsCategory.Player) && (secondBody.categoryBitMask == PhysicsCategory.En)){

collisionWithPerson(firstBody.node as! SKSpriteNode, Person: secondBody.node as! SKSpriteNode)

}

}

func collisionBullet(En: SKSpriteNode, Bullet: SKSpriteNode){

En.removeFromParent()

Bullet.removeFromParent()

score++

Scorelbl.text = "(score)"
}
func collisionWithPerson(En: SKSpriteNode, Person: SKSpriteNode){

En.removeFromParent()

Person.removeFromParent()

view?.presentScene(Next())

Scorelbl.removeFromSuperview()

}
func Spaw(){

var Bullet = SKSpriteNode(imageNamed: "Image-1")

Bullet.zPosition = -5

Bullet.position = CGPointMake(Player.position.x, Player.position.y)

let action = SKAction.moveToY(self.size.height + 30, duration: 1.0)

let actionDone = SKAction.removeFromParent()

Bullet.runAction(SKAction.sequence([action, actionDone]))

Bullet.runAction(SKAction.repeatActionForever(action))

Bullet.physicsBody = SKPhysicsBody(rectangleOfSize: Bullet.size)

Bullet.physicsBody?.categoryBitMask = PhysicsCategory.Bullet

Bullet.physicsBody?.contactTestBitMask = PhysicsCategory.En

Bullet.physicsBody?.affectedByGravity = false

Bullet.physicsBody?.dynamic = false
self.addChild(Bullet)

}
func SpawEn(){

var En = SKSpriteNode(imageNamed: "Image-2")

var minVal = self.size.width / 8

var maxVal = self.size.width - 20

var Point = UInt32(maxVal - minVal)

En.position = CGPoint(x: CGFloat(arc4random_uniform(Point)), y: self.size.height)

En.physicsBody = SKPhysicsBody(rectangleOfSize: En.size)

En.physicsBody?.categoryBitMask = PhysicsCategory.En

En.physicsBody?.contactTestBitMask = PhysicsCategory.Bullet

En.physicsBody?.affectedByGravity = false

En.physicsBody?.dynamic = true
let action = SKAction.moveToY(-60, duration: 3.0)

En.runAction(SKAction.repeatActionForever(action))

let actionDone = SKAction.removeFromParent()
En.runAction(SKAction.sequence([action, actionDone]))

self.addChild(En)

}

override func touchesBegan(touches: Set<UITouch>, withEvent event: UIEvent?) {

/* Called when a touch begins /

for touch in touches {

let location = touch.locationInNode(self)

Player.position.x = location.x

}

}

override func touchesMoved(touches: Set<UITouch>, withEvent event: UIEvent?) {

for touch in touches {

let location = touch.locationInNode(self)

Player.position.x = location.x

}

}

override func update(currentTime: CFTimeInterval) {

/ Called before each frame is rendered /

}

}

Next GameSceneController.swift:

class GameViewController: UIViewController {

override func viewDidLoad() {

super.viewDidLoad()

if let scene = GameScene(fileNamed:"GameScene") {

// Configure the view.

let skView = self.view as! SKView

skView.showsFPS = true

skView.showsNodeCount = true

/ Sprite Kit applies additional optimizations to improve rendering performance /

skView.ignoresSiblingOrder = true

/ Set the scale mode to scale to fit the window */

scene.scaleMode = .AspectFill

skView.presentScene(scene)

}

}

override func shouldAutorotate() -> Bool {

return true

}

override func supportedInterfaceOrientations() -> UIInterfaceOrientationMask {

if UIDevice.currentDevice().userInterfaceIdiom == .Phone {

return .AllButUpsideDown

} else {

return .All

}

}

override func didReceiveMemoryWarning() {

super.didReceiveMemoryWarning()

// Release any cached data, images, etc that aren't in use.

}

override func prefersStatusBarHidden() -> Bool {

return true

}

}

When the enemy enters the plane, we go to the next stage where the switch to the next level is next.swift:

class Next: SKScene{

var RestartB : UIButton!

override func didMoveToView(view: SKView) {

scene?.backgroundColor = UIColor.redColor()
RestartB = UIButton(frame: CGRect(x: 0, y: 0, width: view.frame.size.width / 3, height: 30))

RestartB.center = CGPointMake(view.frame.size.width / 2, view.frame.size.width / 7)

RestartB.setTitle("Restart", forState: UIControlState.Normal)

RestartB.setTitleColor(UIColor.darkGrayColor(), forState: UIControlState.Normal)

RestartB.addTarget(self, action: Selector("Restart"), forControlEvents: UIControlEvents.TouchUpInside)

self.view?.addSubview(RestartB)
}
func Restart(){

self.view?.presentScene(Start(), transition: SKTransition.flipHorizontalWithDuration(0.3))
RestartB.removeFromSuperview()

}

}

struct PhysicssCategory {

static let En: UInt32 = 1

static let Bullet: UInt32 = 2

static let Player: UInt32 = 3
}

And the final document, Start.swift, is basically the next level, as long as it contains everything the same as the first.

The stage is being created, but you don't transfer the file on the basis of which it should be created. That's what you need in the arts:

func Restart(){
let scene = Start(fileNamed: "GameScene")!
scene.scaleMode = .AspectFill
self.view?.presentScene(scene, transition: SKTransition.flipHorizontalWithDuration(0.3))

RestartB.removeFromSuperview()

}
