Question

var actionArray:NSMutableArray = NSMutableArray()
    actionArray.addObject(SKAction.moveTo(finalDestination, duration: NSTimeInterval(moveDuration)))
    actionArray.addObject(SKAction.removeFromParent())

    torpedo.runAction(SKAction.sequence(actionArray as [AnyObject]))

错误：'NSMutableArray'不能隐式转换为'[AnyObject]';你的意思是使用'as'来明确转换吗？

第二个问题，因为我不能经常发布与早期问题非常相似的内容：

var actionArray:NSMutableArray = NSMutableArray()

    actionArray.addObject(SKAction.moveTo(CGPointMake(position, -alien.size.height), duration: NSTimeInterval(duration)))
    actionArray.addObject(SKAction.runBlock({
        var transition:SKTransition = SKTransition.flipHorizontalWithDuration(0.5)
        var gameOverScene:SKScene = GameOverScene(size: self.size, won:false)
        self.view?.presentScene(gameOverScene, transition: transition)
    }))


    actionArray.addObject(SKAction.removeFromParent())

    alien.runAction(SKAction.sequence(actionArray as [SKAction]))

错误：'NSMutableArray'在强制中键入'[SKAction]'

我不知道为什么我会收到此信息，但自从我切换到Xcode 7后，所有这些错误都会弹出。任何帮助都表示赞赏！谢谢！

Answer 1

抱歉应该是...... 1.

var actionArray:[SKAction] = [SKAction]()
actionArray.append(SKAction.moveTo(....
actionArray.append(SKAction.removeFromParent())
torpedo.runAction(SKAction.sequence(actionArray))

var actionArray:[SKAction] = [SKAction]() ditto the rest

NSMutable Array不能与[AnyObject] / NSMutableArray一起在强制中键入SKAction

错误：'NSMutableArray'在强制中键入'[SKAction]'
