Xcode Swift 3 Sprite Kit动画化上下图像

Question

hello I'm coding a app on xcode and i really like to know how to move a SKSpriteNode up and down smooth kind of animated (just like the in Pop The Lock when you complete the level)

SKSpriteNode code

    Lock = SKSpriteNode(imageNamed: "Lock")
    Lock.size = CGSize(width: 182, height: 170)
    Lock.position = CGPoint(x: CGRectGetMidX(self.frame), y: (self.frame.height / 2 + 180))
    Lock.zPosition = -1
    self.addChild(Lock)

Answer 1

You can use SKAction for example.

//Move Up
let MoveUp = SKAction.MoveToY(self.frame.height / 2 + 280) // +100 up
Lock.runAction(MoveUp)

//Move Down
let MoveDown = SKAction.MoveToY(self.frame.height / 2 + 80) // -100 down
Lock.runAction(MoveDown)
