Swift SpriteKit SKVideoNode仅播放一次

Question

嗨，我正在尝试在SKVideoNode上播放视频swift这是我的代码，但它只播放一次，如果我点击VideoSprite它不播放，但打印“我们点击了视频”我已经搜索过，但似乎找不到答案谢谢查看

import SpriteKit
import AVFoundation

class GameScene: SKScene
{
    var VideoSprite = SKVideoNode()

    override func didMoveToView(view: SKView)
    {
        LoadVideo("9.mp4")
    }

    func LoadVideo(FileToPlay:String)
    {
        VideoSprite =  SKVideoNode (videoFileNamed:FileToPlay)
        VideoSprite.position = CGPointMake(size.width/2, size.height/2);
        VideoSprite.name = "VideoSprite"
        VideoSprite.zPosition = 2
        addChild(VideoSprite)
    }


    override func touchesBegan(touches: Set<NSObject>, withEvent event: UIEvent)
    {
        for touch in (touches as! Set<UITouch>)
        {
            var touch: UITouch = touches.first as! UITouch
            var location = touch.locationInNode(self)
            var node = self.nodeAtPoint(location)
            if (node.name == "VideoSprite")
            {
                println("we Clicked the video")
                VideoSprite.play()
            }

        }
    }

}

嗨，我想我已经破解了，我在上面添加了另一个videoSKnode并重命名它，这样用户就不能点击原始视频，然后在延迟后我删除它，延迟需要是视频运行的时间我使用了一个很酷的延迟功能，我在互联网上发现不记得是从哪里来的，所以感谢曾经写过它的人，我希望这可以帮助其他人我在更新功能中尝试了暂停的bool，但没有运气？

import SpriteKit
import AVFoundation
import AVKit
class GameScene: SKScene
{

 var VideoSprite = SKVideoNode()// emptey Videonode

    func delay(delay:Double, closure:()->())// function for delay
    {
        dispatch_after(
            dispatch_time(
                DISPATCH_TIME_NOW,
                Int64(delay * Double(NSEC_PER_SEC))
            ),
            dispatch_get_main_queue(), closure)
    }


    override func didMoveToView(view: SKView)
    {

    LoadVideo("9.mp4") // run function to load video
    VideoSprite.pause()// pauses video ready to play
    }

    func LoadVideo(FileToPlay:String)
    {

        VideoSprite =  SKVideoNode (videoFileNamed:FileToPlay)// fill spritenode with video file
        VideoSprite.position = CGPointMake(size.width/2, size.height/2);  // set size
        VideoSprite.name = "VideoSprite" // give it a name
        VideoSprite.zPosition = 1 // set its z position
        VideoSprite.play()// play video
        addChild(VideoSprite)// add video node to the sceene
    }


    override func touchesBegan(touches: Set<NSObject>, withEvent event: UIEvent)
    {
        for touch in (touches as! Set<UITouch>)
        {
            var touch: UITouch = touches.first as! UITouch
            var location = touch.locationInNode(self)
            var node = self.nodeAtPoint(location)
    println(node.name)

            if (node.name == "VideoSprite")// we click on video
            {

                LoadVideo("9.mp4") /// load another video ontop
                VideoSprite.name = "temp" //name it temp so user cant click to add more videonodes
                delay(1.8 )// wait for time
                    {
                     self.VideoSprite.removeFromParent()// then remove
                     }

            }
        }
    }
