我正在尝试从我的EndScene重新加载GameScene。这个想法是玩家将击中＆＃34;重新启动＆＃34;按钮，重新加载GameScene，允许他们再试一次。这是我的两个场景的代码。有没有人有办法解决吗？请给我一些我需要的确切代码，这是我第一次使用Xcode，而且我是新手使用代码。这将有助于我更好地了解如何在将来处理这样的问题。
以下是GameScene的代码：
var Highscore = Int()
var Score = Int()
var Player = SKSpriteNode (imageNamed: "good.png")
var ScoreLbl = UILabel()
override func didMoveToView(view: SKView) {
var HighscoreDefault = NSUserDefaults.standardUserDefaults()
if (HighscoreDefault.valueForKey("Highscore") != nil){
Highscore = HighscoreDefault.valueForKey("Highscore") as! NSInteger
}
else {
Highscore = 0
}
physicsWorld.contactDelegate = self
self.scene?.backgroundColor = UIColor.blackColor()
self.addChild(SKEmitterNode(fileNamed: "Rain"))
Player.position = CGPointMake(self.size.width / 2, self.size.width / 6)
Player.physicsBody = SKPhysicsBody(rectangleOfSize: Player.size)
Player.physicsBody?.affectedByGravity = false
Player.physicsBody?.categoryBitMask = PhysicsCategory.Player
Player.physicsBody?.contactTestBitMask = PhysicsCategory.Enemy
Player.physicsBody?.dynamic = false
var Timer = NSTimer.scheduledTimerWithTimeInterval(0.4, target: self, selector: Selector("SpawnBullets"), userInfo: nil, repeats: true)
var EnemyTimer = NSTimer.scheduledTimerWithTimeInterval(0.8, target: self, selector: Selector("SpawnEnemies"), 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(red: 0.1, green: 0.1, blue: 1.0, alpha: 0.3)
ScoreLbl.textColor = UIColor.whiteColor()
self.view?.addSubview(ScoreLbl)
}
func didBeginContact(contact: SKPhysicsContact) {
var firstBody : SKPhysicsBody = contact.bodyA
var secondBody : SKPhysicsBody = contact.bodyB
if ((firstBody.categoryBitMask == PhysicsCategory.Enemy) && (secondBody.categoryBitMask == PhysicsCategory.Bullet) || (firstBody.categoryBitMask == PhysicsCategory.Bullet) && (secondBody.categoryBitMask == PhysicsCategory.Enemy)){
CollisionWithBullet(firstBody.node as! SKSpriteNode, Bullet: secondBody.node as! SKSpriteNode)
}
else if ((firstBody.categoryBitMask == PhysicsCategory.Enemy) && (secondBody.categoryBitMask == PhysicsCategory.Player) || (firstBody.categoryBitMask == PhysicsCategory.Player) && (secondBody.categoryBitMask == PhysicsCategory.Enemy)){
CollisionWithPerson(firstBody.node as! SKSpriteNode, Person: secondBody.node as! SKSpriteNode)
}
}
func CollisionWithBullet(Enemy: SKSpriteNode, Bullet: SKSpriteNode){
Enemy.removeFromParent()
Bullet.removeFromParent()
Score++
ScoreLbl.text = "\(Score)"
}
func CollisionWithPerson(Enemy: SKSpriteNode,Person: SKSpriteNode){
var ScoreDefault = NSUserDefaults.standardUserDefaults()
ScoreDefault.setValue(Score, forKey: "Score")
ScoreDefault.synchronize()
if (Score > Highscore){
var HighscoreDefault = NSUserDefaults.standardUserDefaults()
HighscoreDefault.setValue(Score, forKey: "Highscore")
}
Enemy.removeFromParent()
Person.removeFromParent()
self.view?.presentScene(EndScene())
ScoreLbl.removeFromSuperview()
self.removeAllActions()
}
func SpawnBullets() {
var Bullet = SKSpriteNode (imageNamed: "bullet.png")
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.physicsBody = SKPhysicsBody(rectangleOfSize: Bullet.size)
Bullet.physicsBody?.categoryBitMask = PhysicsCategory.Bullet
Bullet.physicsBody?.contactTestBitMask = PhysicsCategory.Enemy
Bullet.physicsBody?.affectedByGravity = false
Bullet.physicsBody?.dynamic = false
self.addChild(Bullet)
}
func SpawnEnemies () {
var Enemy = SKSpriteNode (imageNamed: "bad.png")
var MinValue = self.size.width / 8
var MaxValue = self.size.width - 15
var Spawnpoint = UInt32(MaxValue - MinValue)
Enemy.position = CGPointMake(CGFloat(arc4random_uniform(Spawnpoint)), self.size.height)
Enemy.physicsBody = SKPhysicsBody(rectangleOfSize:Enemy.size)
Enemy.physicsBody?.categoryBitMask = PhysicsCategory.Enemy
Enemy.physicsBody?.contactTestBitMask = PhysicsCategory.Bullet
Enemy.physicsBody?.affectedByGravity = false
Enemy.physicsBody?.dynamic = true
let action = SKAction.moveToY(-70, duration: 2.5)
let ActionDone = SKAction.removeFromParent()
Enemy.runAction(SKAction.sequence([action, ActionDone]))
Enemy.runAction(SKAction.repeatActionForever(action))
self.addChild(Enemy)
}
override func touchesBegan(touches: Set<NSObject>, withEvent event: UIEvent) {
for touch: AnyObject in touches {
let location = touch.locationInNode(self)
Player.position.x = location.x
}
}
override func touchesMoved(touches: Set<NSObject>, withEvent event: UIEvent) {
for touch: AnyObject in touches {
let location = touch.locationInNode(self)
Player.position.x = location.x
}
}
override func update(currentTime: CFTimeInterval) {
/* Called before each frame is rendered */
}
以下是EndScene的代码：
var RestartBtn : UIButton!
var Highscore : Int!
var ScoreLbl : UILabel!
var HighscoreLbl : UILabel!
override func didMoveToView(view: SKView) {
scene?.backgroundColor = UIColor.blackColor()
RestartBtn = UIButton(frame: CGRect(x: 0, y: 0, width: view.frame.size.width / 3, height: 30))
RestartBtn.center = CGPoint(x: view.frame.size.width / 2, y: view.frame.size.width / 7)
RestartBtn.setTitle("Restart", forState: UIControlState.Normal)
RestartBtn.setTitleColor(UIColor.whiteColor(), forState: UIControlState.Normal)
RestartBtn.addTarget(self, action: Selector("Restart"), forControlEvents: UIControlEvents.TouchUpInside)
self.view?.addSubview(RestartBtn)
var ScoreDefault = NSUserDefaults.standardUserDefaults()
var Score = ScoreDefault.valueForKey("Score") as! NSInteger
var HighscoreDefault = NSUserDefaults.standardUserDefaults()
Highscore = HighscoreDefault.valueForKey("Highscore") as! NSInteger
ScoreLbl = UILabel(frame: CGRect(x: 0, y: 0, width: view.frame.size.width / 3, height: 30))
ScoreLbl.center = CGPoint(x: view.frame.size.width / 2, y: view.frame.size.width / 4)
ScoreLbl.text = "\(Score)"
self.view?.addSubview(ScoreLbl)
ScoreLbl.textColor = UIColor.whiteColor()
HighscoreLbl = UILabel(frame: CGRect(x: 0, y: 0, width: view.frame.size.width / 3, height: 30))
HighscoreLbl.center = CGPoint(x: view.frame.size.width / 2, y: view.frame.size.width / 2)
HighscoreLbl.text = "\(Highscore)"
self.view?.addSubview(HighscoreLbl)
HighscoreLbl.textColor = UIColor.whiteColor()
}
func Restart(){
self.view?.presentScene(GameScene(), transition: SKTransition.crossFadeWithDuration(0.3))
RestartBtn.removeFromSuperview()
ScoreLbl.removeFromSuperview()
HighscoreLbl.removeFromSuperview()
}
}
非常感谢能够提供帮助的任何人！那意义重大！ ：）
