创建重复的动作序列

有时需要重复或按顺序执行操作。此示例将使节点淡入和淡出总共 3 次。

在 Swift 中：

let node = SKSpriteNode(imageNamed: "image")
let actionFadeOut = SKAction.fadeOutWithDuration(1.0)
let actionFadeIn = SKAction.fadeInWithDuration(1.0)
let actionSequence = SKAction.sequence([actionFadeOut, actionFadeIn])
let actionRepeat = SKAction.repeatAction(actionSequence, count: 3)
node.runAction(actionRepeat)
