runAction SKAction.sequence无效

Question

我无法让runAction方法适用于此代码块。我不确定我做错了什么或者块外有什么问题，但是如果有人看到任何内部错误，让我们从那里开始（*编辑包括整个功能）。所有变量都有效，我得到零编译错误，程序似乎跳过了行currentTestIndicator.runAction(SKAction.sequence(runCheck))。除recurse内的所有打印语句外，所有打印语句都有效，同时current++也未被调用。我尝试在没有recurse的情况下运行代码，但仍然无效。想法？

func runLevelCheck(node: SKSpriteNode, _ state: SKSpriteNode, _ bluePatterns:Array<Array<String>>, _ blueSize: CGFloat, _ blueLocations: Array<CGPoint>, _ greenPatterns:Array<Array<String>>, _ greenSize: CGFloat, _ greenLocations:Array<CGPoint>, _ redPatterns:Array<Array<String>>, _ redSize: CGFloat, _ redLocations:Array<CGPoint>, _ orangePatterns:Array<Array<String>>, _ orangeSize: CGFloat, _ orangeLocations:Array<CGPoint>)->Bool {

    var passLevel = true
    var current = 0
    let currentTestIndicator = SKSpriteNode()
    currentTestIndicator.name = "indicator"
    currentTestIndicator.size = CGSizeMake(0, 128)
    blueLocations[current].y)
    currentTestIndicator.anchorPoint = CGPoint(x: 0.0, y: 0.5)
    currentTestIndicator.zPosition = 0
    node.addChild(currentTestIndicator)

    let patterns = [bluePatterns, greenPatterns, redPatterns, orangePatterns]
    let sizes = [blueSize, greenSize, redSize, orangeSize]
    let locations = [blueLocations, greenLocations, redLocations, orangeLocations]
    let colors = [color("Light Blue 01"), color("Light Green 01"), color("Light Red 01"), color("Light Orange 01")]

    for sets in patterns {
      for rows in sets {
        if rows != [] {
          print("Current set: \(current)")
          print(rows)
          currentTestIndicator.color = colors[current]
          currentTestIndicator.position = CGPoint(x: 0.0, y: locations[current][0].y)
          print(currentTestIndicator.position)
          print("Sizes current = \(sizes[current])")

          let growRight = SKAction.resizeToWidth(sizes[current], duration: 0.2)
          let recurse = SKAction.runBlock() {
            recursion(state, rows, 0, 0, &passLevel)
            current++
            print("Changed current value to \(current)")
          }
          let pause = SKAction.waitForDuration(5.0)
          let shrinkLeft = SKAction.resizeToWidth(0, duration: 0.2)
          let runCheck = [growRight, recurse, pause, shrinkLeft]
          currentTestIndicator.runAction(SKAction.sequence(runCheck))
        }
      }
      current = 0
    }

    currentTestIndicator.removeFromParent()

    print("Ran level check")

    switch passLevel {
    case true:
      print("Level passed")
    case false:
      print("Lavel failed")
    }
    return passLevel
}
