如何在ios场景工具包swift中添加自定义动画(How to add custom animations in ios scene kit swift)

我正在制作一个带有场景套件的游戏，其中一部分掷骰子生成一个数字，我已经在3DS max 2016中制作了骰子。我可以在3DS max上轻松制作动画，但我如何将它加载到我的场景中？ 我已经加载了没有动画的骰子，但我不确定如何加载骰子动画以使其滚动。

我打算做的是让xcode生成一个数字，并使用该数字从不同的文件中选择一个文件，例如animation1，animation2。 假设生成的数字是2它将运行animation2。

谢谢

I am making a game with scene kit and part of it rolls some dice to generate a number, i have made the dice in 3DS max 2016. I can make the animations easily on 3DS max, but how would i load it into my scene? I have loaded in a dice with no animations, but I am not sure how I can load the dice animations so that it rolls.

What I intend to do is make xcode generate a number, and with that number is chooses a file out of different files, e.g. animation1, animation2. Say the number generated was 2 it would run animation2.

Thanks

您可以使用OpenCOLLADA插件从3DS Max导出动画。 然后你可以使用SCNSceneSource获取动画，例如：

let src = SCNSceneSource(URL: yourSceneURL, options: nil)
let node = src.entryWithIdentifier("yourNodeID", withClass: SCNNode.self) as SCNNode
let animation = node.entryWithIdentifier("yourAnimationID", withClass: CAAnimation.self) as CAAnimation
 
 将动画提取到数组，并使用SCNNode的addAnimation（forKey :)将随机附加到您的节点

Extract animations to array, and attach random one to your node with SCNNode's addAnimation(forKey:)
