Question

您好我正试图在swift中播放SKVideoNode上的视频这是我的代码可以工作，但它只播放一次，如果我点击VideoSprite它没有播放但是打印＃34;我们点击了视频＆＃34;我已经搜索过了，但感谢你找不到答案

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，我想我已经破解了它我在顶部添加另一个videoSKnode并重命名，以便用户无法点击原始视频然后在延迟后我将其删除这种延迟需要是视频运行的时间我使用一个很酷的功能延迟我在互联网上找不到记得从哪里，所以感谢谁写过它我希望这可能会帮助别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
                     }

            }
        }
    }



}

Swift SpriteKit SKVideoNode只播放一次
