我該如何做一個運行塊動作Swift SpriteKit

Question

嗨我一直在試圖做很長一段時間，我使用Swift SpriteKit，我的問題是我需要爲一個節點做一個runBlock動作我該如何做運行功能的動作我試過這個：

 var a = SKAction.runBlock({() in self.spawn1()}) 

對你的信息spawn1是函數。
在此先感謝！

繼承人我的第一個答案的評論幫助代碼：

你把所有的功能

Answer 1

var a = SKAction.runBlock({ self.spawn1() }) 
yournode.runAction(a)
