Question

我的简单游戏出了问题。作为播放器，背景，地板，硬币，乐谱文本等的每张图片都设置为“添加孩子”＃34;在函数didMoveToView中。它看起来像这样：

override func didMoveToView(view: SKView) {



    balon.physicsBody = SKPhysicsBody(circleOfRadius: balon.size.width/2)
    balon.physicsBody?.dynamic = true
    balon.physicsBody?.categoryBitMask = physics.Balon
    balon.physicsBody?.contactTestBitMask = physics.Moneta
    balon.physicsBody?.collisionBitMask = physics.None
    balon.physicsBody?.usesPreciseCollisionDetection = true





    physicsWorld.gravity = CGVector(dx: 0,dy: 0)
    physicsWorld.contactDelegate = self





     /////////////////// MOVE COINS ///////////////////////////////////////


    runAction(SKAction.repeatActionForever(
        SKAction.sequence([
            SKAction.runBlock(addCoin),
            SKAction.waitForDuration(1.0)
            ])
        ))


    /////////////////// MOVE BOMB ///////////////////////////////////////



    runAction(SKAction.repeatActionForever(
        SKAction.sequence([
            SKAction.runBlock(addBomb),
            SKAction.waitForDuration(1.0)
            ])
        ))








    self.backround.position = CGPointMake(CGRectGetMidX(self.frame), CGRectGetMidY(self.frame))

    self.runningBar.anchorPoint = CGPointMake(0, 0.5)

    self.runningBar.position = CGPointMake(CGRectGetMinX(self.frame), CGRectGetMinY(self.frame))


    self.orginalBarPosition = self.runningBar.position.x

    self.MaxBarPos = self.runningBar.size.width - self.frame.size.width

    self.MaxBarPos *= -1


    self.balonBaseLine = self.runningBar.position.y + (self.runningBar.size.height/2) + (self.balon.size.height/2)
    self.balon.position = CGPointMake(CGRectGetMidX(self.frame) - self.balon.size.width * 2, CGRectGetMidY(self.frame))



    self.backround.anchorPoint = CGPointMake(0.5, 0.5)

    self.originalBackgroundPosition = self.backround.position.x

    self.maxBackgroundPosition = self.backround.size.width - self.frame.size.width * 1.11

    self.maxBackgroundPosition *= -1


    scoreLabel.text = "Score: 0"
    scoreLabel.fontSize = 16
    scoreLabel.fontColor = SKColor.blackColor();
    scoreLabel.position = CGPoint(x: self.frame.width/2, y: self.frame.height/2)


    addChild(scoreLabel)

    addChild(backround)

    addChild(runningBar)

    addChild(balon) }

有一个问题..有时候一切正常但通常在我运行我的程序时会出现一些问题。例如背景和硬币出现但玩家（Balon）没有，或者有时硬币和炸弹出现但地板（movingBar）没有。 RunningBar正在移动，它在覆盖功能更新（currentTime：NSTimeInterval）中声明，就像移动背景（它是天空）一样。我不明白为什么有时候一切都好，大多数都不行...... 编译项目时我没有错误。我真的很想了解这有什么不对。

感谢您的帮助！
