5秒后开始转换

Question

你好，如何进行过渡

let transitionType = SKTransition.crossFadeWithDuration (2.0)

5秒后开始？

我的代码：

let nextLevel = level2(size: size)
nextLevel.scaleMode = scaleMode
let transitionType = SKTransition.crossFadeWithDuration(2.0)       
view?.presentScene(nextLevel,transition: transitionType)

Answer 1

您可以将SKAction.waitForDuration与SKAction.runBlock结合使用在 sequence中。

let wait = SKAction.waitForDuration(5)
let action = SKAction.runBlock {
    view?.presentScene(nextLevel, transition: transitionType)
}

self.runAction(SKAction.sequence([wait, action]))
