SKTransition问题和场景加载

所以我现在正在制作游戏。我有很多场景:菜单,设置,gameScene和GameOverScene。

ALMOST ALL场景之间的转换没有问题,我用来转换的代码是: (例如菜单到GameScene)

let secondScene = GameScene(size: self.size)
let transition = SKTransition.pushWithDirection(.Up, duration: 0.7)
secondScene.scaleMode = SKSceneScaleMode.AspectFill
self.scene!.view?.presentScene(secondScene, transition: transition)

然而,我的GameScene到GameOverScene是非常小故障。通常会有一段很长的停顿。

GameOverScene的全部内容是:

import Foundation
import SpriteKit

class GameOverScene: SKScene {


    override func didMoveToView(view: SKView) {
        let myLabel = SKLabelNode(fontNamed:"American Typrewriter")
        myLabel.text = "Game Over!";
        myLabel.fontSize = 45;
        myLabel.position = CGPoint(x:CGRectGetMidX(self.frame), y:CGRectGetMidY(self.frame));

        self.addChild(myLabel)
   }
}

因此,我认为这不太可能是推迟转型的原因。

我用来调用'游戏结束'的代码是:

override func update(currentTime: CFTimeInterval) {

if sprite.position.y < 100 {gameOver()}
}

func gameOver() {

    // Loads GameOver Scene //
    let secondScene = GameOverScene(size: self.size)


    // Creates vibration //
    AudioServicesPlayAlertSound(SystemSoundID(kSystemSoundID_Vibrate))


        func boatSink() {
        sprite.physicsBody = nil
        sprite.physicsBody?.affectedByGravity = false
        sprite.physicsBody?.dynamic = false

        let spritefly = SKAction.moveTo(CGPointMake(400,20), duration:2.0)
        car.runAction(spritefly) }



    let transition = SKTransition.pushWithDirection(.Up, duration: 3.0) 
    let nextScene = GameOverScene(size: scene!.size)
    nextScene.scaleMode = .AspectFill

    scene?.view?.presentScene(nextScene, transition: transition)        
}

我已尝试使用延迟,例如使用:

let skView = self.view! as SKView
            let scene = GameOverScene(size: self.scene!.size)
            scene.size = skView.bounds.size
            scene.scaleMode = .AspectFill

  let time = dispatch_time(dispatch_time_t(DISPATCH_TIME_NOW), 1 * Int64(NSEC_PER_SEC))
        dispatch_after(time, dispatch_get_main_queue()) {



            let sceneTransition = SKTransition.doorsCloseHorizontalWithDuration(2.0)
            sceneTransition.pausesOutgoingScene = true;
            skView.presentScene(scene, transition: sceneTransition)}

要加载时间,但这不起作用。

我也试过使用'pausesOutgoingScene'和暂停IncomingScene'无济于事。

我终于尝试使用以下方法将当前场景减速到0.0

func pauseGameScene() {
        self.physicsWorld.speed = 0.0
        self.speed = 0.0
    }

虽然这只会阻止代码继续前进。

我的问题是: 有没有什么东西真的很明显,我没有考虑过我的过渡? 2.有没有办法提前加载所有场景,我相信这可能只会提供微小的改进,但它绝对是一个我还没有看过的领域。
