swift – 完成块从未在组的SKAction序列结束时调用

我非常抱歉这是一个代码转储…因为我不知道为什么每个部分都有效,除了调用完成.

除了完成之外,没有调用完成的SKAction运行.就是这个：

curtain.run(fadeMoveWipeAndReveal,completion: {onDone(),print("I'm done!!!!")})

在以下课程中：

import SpriteKit

class WipeCurtain: SKSpriteNode {

    var wipeCurtainBase: SKSpriteNode?
    var returnable = SKNode()
    var moveRight = SKAction()
    var node = SKNode()

    init(     color: SKColor,size: CGSize,time: TimeInterval,reveal: @escaping () -> (),onDone: @escaping () -> ())
    {
        super.init(texture: nil,color: color,size: size)
        wipeCurtainBase = SKSpriteNode(color: color,size: size)

        let show = SKAction.run(reveal)

        let fadeIn = createFadeIn(duration: time)
        let moveRight = createMoveRight(duration: time)
        let wipeRight = createWipeRight(duration: time)

        let fadeAndMove = SKAction.group( [ fadeIn,moveRight ] )
        let wipeAndReveal = SKAction.group( [ show,wipeRight ] )
        let fadeMoveWipeAndReveal = SKAction.sequence( [ fadeAndMove,wipeAndReveal ] )

        if let  curtain = self.wipeCurtainBase {
            curtain.anchorPoint = CGPoint(x: 1,y: 0)
            curtain.position = CGPoint(x: frame.size.width,y: 0)
            curtain.zPosition = -1
            curtain.name = "wipe"
            curtain.run(fadeMoveWipeAndReveal,completion: {
                onDone()
                print("I'm done!!!!")
            })
        }
    }

    func createFadeIn(duration: TimeInterval) -> SKAction {
        let fadeIn = SKEase
            .fade(
                easeFunction: .curveTypeLinear,easeType: .easeTypeIn,time: duration,fromValue: 0,toValue: 1
            )
        return fadeIn
        }

    func createMoveRight(duration: TimeInterval) -> SKAction {
        let moveRight = SKEase
            .move(
                easeFunction: .curveTypeExpo,easeType: .easeTypeOut,duration: duration,origin: CGPoint(
                    x: 0,y: 0),destin: CGPoint(
                    x: frame.size.width,y: 0)
            )
        return moveRight
        }

    func createWipeRight(duration: TimeInterval) -> SKAction {
        let wipeRight = SKEase
            .createFloatTween(
                start: 1,ender: 0,timer: duration,easer: SKEase
                    .getEaseFunction(
                        .curveTypeExpo,easeType: .easeTypeOut
                    ),setterBlock: {(node,i) in
                node.xScale = i}
            )
        return wipeRight
        }

    func wipeWith() -> SKNode {
        if let curtain = wipeCurtainBase?.copy() as! SKSpriteNode? {
            returnable = curtain
            }
        return returnable
        }

    required init?(coder aDecoder: NSCoder) {
        fatalError("init(coder:) has not been implemented")
    }
}

更新：

这是使这项工作的gameScene,Xcode SpriteKit模板的一个非常轻微的修改版本：

import SpriteKit
import GameplayKit

class GameScene: SKScene {

    private var swipe: WipeCurtain?

    override func didMove(to view: SKView) {
        swipe = WipeCurtain(color: .brown,size: frame.size,time: 1,reveal: self.showOrNot,onDone: self.previewer
            )
        }

    func showOrNot(){
        print(" Deciding to show or not.......")
        }

    func previewer(){
        print("now running the previewer")
        }

    func touchDown(atPoint pos : CGPoint) {
        addChild(swipe!.wipeWith())
        }

    override func touchesBegan(_ touches: Set<UITouch>,with event: UIEvent?) {
        for t in touches { self.touchDown(atPoint: t.location(in: self)) }
        }
}
