如何快速执行功能5秒钟

Question

我正在创建一个游戏，此功能用作将精灵缩小的功能。我希望此函数执行5秒钟，然后将此5秒计时器附加到标签上，以进行倒计时。函数结束后，将精灵返回其原始大小。

该函数只是通过设置比例来缩小节点。

func shrinkShip() { spaceShip.scale(to: CGSize(width: 60, height: 40)) }

Answer 1

UIView.animate(withDuration: 5, animations: {
        self.spaceShip.transform = CGAffineTransform(scaleX: 60, y: 40)
},
completion: { _ in
    UIView.animate(withDuration: 2) {
        self.spaceShip.transform = .identity // Reset your view
    }
})

Answer 2

let node =  SKSpriteNode()
let scale = SKAction.scale(by: 0.1, duration: 5.0)
let sequence = SKAction.sequence([
    scale,
    SKAction.customAction(withDuration: 0, actionBlock: { (_, _) in
        // Change label?
    }),
    scale.reversed()
])
node.run(sequence)
