无法创建SKActions数组

问题描述

我和斯威夫特SpriteKit试验，但不知何故似乎无法创建一个序列中使用动作的数组。我已经把它分解到尝试和针点的问题，但至今没有运气。

I'm experimenting with SpriteKit in Swift but somehow seem unable to create an array of actions to use in a sequence. I've split it up to try and pin-point the problem, but no luck so far.

func animateBackground(){
    let moveLeft = SKAction.moveByX(100, y: 0, duration: 3)
    moveLeft.timingMode = SKActionTimingMode.EaseInEaseOut
    let moveRight = SKAction.reversedAction(moveLeft)
    let actions = [moveLeft, moveRight] // <--- here there be dragons/trouble
    let sequence = SKAction.sequence(actions)
    let repeat = SKAction.repeatActionForever(sequence)
}

在试图创建行动阵列我得到错误的不能转换前pression的类型'阵'输入'ArrayLiteralConvertible'的所以，我想我可能需要更明确，并试图将其更改为

When trying to create the actions-array I get the error "Cannot convert the expression's type 'Array' to type 'ArrayLiteralConvertible' " So, I thought I might need to be more explicit and attempted to change it to

var actions: SKAction[] = [moveLeft, moveRight]

这似乎降低了房子，而不是一个好办法，导致<一个href=\"http://stackoverflow.com/questions/24063055/error-x$c$c-6-error-sourcekit-terminated-editor-functionality-temporaly-lim\">SourceKit终止错误...

This seemed to bring down the house, and not in a good way, resulting in the SourceKit terminated bug...

推荐答案

您要添加一个功能到数组用于MoveRight的，而不是SKAction本身。尝试使用这个代替：

You're adding a function to the array for moveRight, not the SKAction itself. Try using this instead:

let moveRight = SKAction.reversedAction(moveLeft)()
